+# Component Selection
+
+Component choices for the re-BBA-RB replacement PCB, with rationale.
+
+---
+
+## Power Architecture
+
+The SP1 connector supplies **12 V on pin 5**. The design needs two rails:
+
+| Rail | Consumers | Current budget |
+|------|-----------|----------------|
+| 3.3 V | FPGA I/O (VCCIO all banks), W5100S VCC/AVCC, config flash | ~300 mA |
+| 1.2 V | FPGA core (VCC), FPGA PLL (VCCPLL) | ~80 mA |
+
+A linear regulator dropping 12 V → 3.3 V at 300 mA would dissipate ~2.6 W — unacceptable in the enclosed GameCube bay. The chosen topology uses a **switching buck** for the large drop and a **low-dropout linear** for the small 3.3 V → 1.2 V step:
+
+```
+12 V ──► TPS562201DDCR (buck) ──► 3.3 V ──► AP2112K-1.2 (LDO) ──► 1.2 V
+         ~90 % efficient                      105 mW dissipated
+         ~0.3 W heat                          (2.1 V × 50 mA)
+```
+
+Power-on sequencing is naturally correct: the LDO input is the buck output, so 1.2 V cannot rise before 3.3 V is established. The iCE40 requires core (1.2 V) ≤ I/O (3.3 V) during power-up — this topology satisfies that without any additional sequencing logic.
+
+---
+
+## Power Components
+
+### TPS562201DDCR — 12 V → 3.3 V Buck Converter
+
+| Property | Value |
+|----------|-------|
+| Manufacturer | Texas Instruments |
+| Package | SOT-23-5 (DDCR suffix) |
+| Input voltage | 4.5 – 17 V |
+| Output current | 2 A |
+| Efficiency | ~90 % at this operating point |
+| External components | Inductor + 3 capacitors |
+
+**Why this part:**
+The DDCR (SOT-23-5) variant was chosen over the DRLR (SOT-23-6) because the extra pin on the -6 package is only an EN (enable) control. This supply is always-on — it powers up with the GameCube and powers down with it — so EN tied to VIN internally (as the -5 package does) is the correct behaviour and removes one pin and one footprint variant to manage.
+
+The SOT-23-5 footprint is in KiCad's official library (`Package_TO_SOT_SMD:SOT-23-5`). The symbol is available from SnapEDA.
+
+**Why not a linear regulator:** dropping 8.7 V at 300 mA in a TO-252 or SOT-223 LDO dissipates ~2.6 W. A heatsink would be required and the GameCube bay has no airflow.
+
+---
+
+### AP2112K-1.2TRG1 — 3.3 V → 1.2 V LDO
+
+| Property | Value |
+|----------|-------|
+| Manufacturer | Diodes Inc. |
+| Package | SOT-23-5 |
+| Input voltage | 1.5 – 6 V |
+| Output voltage | 1.2 V fixed |
+| Output current | 600 mA |
+| Dropout voltage | 250 mV @ 600 mA |
+| Noise | 50 µV rms |
+
+**Why this part:**
+The FPGA core supply needs a fixed 1.2 V with low noise (PLL and core logic are sensitive to supply ripple). The AP2112K is widely used for exactly this purpose in iCE40 and other FPGA designs.
+
+Previously considered alternatives were rejected:
+- **LP2985**: no 1.2 V fixed variant in the standard product family (lowest is 2.5 V).
+- **TLV1117 fixed**: minimum fixed output is 1.25 V, not 1.2 V; the adjustable version needs two resistors and has worse accuracy.
+- **LM1117-1.2**: valid fallback, available in KiCad, but larger SOT-223 package with higher dropout.
+
+The AP2112K is available in the Digikey KiCad library. Heat dissipation: (3.3 − 1.2) V × 80 mA = 168 mW — well within SOT-23-5 ratings.
+
+---
+
+## Core Silicon
+
+### iCE40UP5K-SG48ITR — FPGA
+
+| Property | Value |
+|----------|-------|
+| Manufacturer | Lattice Semiconductor |
+| Package | QFN-48 (SG48), 7 × 7 mm |
+| Logic cells | 5280 LUT4 |
+| SPRAM | 128 kB (4 × SB_SPRAM256KA) |
+| I/O banks | 3 (VCCIO per bank, up to 3.3 V) |
+
+Unchanged from the iCEbreaker development platform. The design was written and validated for this device. The SG48 QFN package has ~34 usable I/O; the design uses 21 (5 EXI + 15 W5100 + 1 clock), leaving ~13 free for expansion or debug headers.
+
+Symbols and footprints: available from SnapEDA and the iCEbreaker community KiCad libraries.
+
+---
+
+### W5100S-L — Ethernet MAC/PHY
+
+| Property | Value |
+|----------|-------|
+| Manufacturer | WIZnet |
+| Package | QFN-48 |
+| Interface | Indirect parallel bus (IDM), A[1:0] + D[7:0] |
+| Power supply | 3.3 V single supply (internal LDO for core) |
+| Max throughput | ~27 Mbit/s (matches EXI ceiling) |
+
+**Why W5100S over original W5100:**
+The W5100S is a register-compatible drop-in upgrade. The firmware targets the W5100 register map, which is identical on the W5100S. Benefits of the S variant:
+- Available in QFN-48 (smaller and easier to hand-solder than LQFP)
+- Lower power consumption
+- Single 3.3 V supply — the W5100S has an internal core LDO, so no separate 1.2 V rail is needed for the ethernet chip (unlike some original W5100 versions)
+
+**Why parallel bus over SPI (W5500):** The parallel IDM bus runs at 24 MHz synchronous clock and achieves ~27 Mbit/s — matching the EXI ceiling. The W5500 SPI path is limited to ~12 Mbit/s by the operating logic speed on the iCE40UP5K (~40 MHz ceiling for the W5500 transaction FSM, not just the bit-bang). W5100 is the throughput path for bulk ROM streaming. See CLAUDE.md "W5100 vs W5500" for the full analysis.
+
+**Only 2 address pins wired (A[1:0]):** The W5100S in Indirect Data Mode (IDM) exposes only 4 registers on the bus — MR, IDM_AR0 (address high), IDM_AR1 (address low), IDM_DR (data). A[1:0] selects between them; all access to the full 16-bit register/buffer space is handled by writing the target address into IDM_AR first. The board ties A[14:2] to GND.
+
+WIZnet provides official KiCad symbols and footprints on their GitHub.
+
+---
+
+### W25Q32JVSSIQ — SPI Configuration Flash
+
+| Property | Value |
+|----------|-------|
+| Manufacturer | Winbond |
+| Package | SOIC-8 |
+| Capacity | 32 Mbit (4 MB) |
+
+The iCE40UP5K loads its bitstream from an external SPI flash at power-on. 32 Mbit is ample — the compressed bitstream is well under 1 MB. SOIC-8 footprint is in KiCad's official library (`Package_SO:SOIC-8`).
+
+---
+
+## Clocks
+
+### 12 MHz Crystal — FPGA PLL Reference
+
+The iCE40's internal PLL requires an external reference. The design uses 12 MHz (DIVR=0, DIVF=71, DIVQ=4) to generate 54 MHz for the EXI capture domain. The internal HFOSC (48 MHz ÷ 2 = 24 MHz) is used for the EXI and sync domains.
+
+Suggested footprint: 3.2 × 2.5 mm SMD crystal (e.g. ABM8G series).
+
+### 25 MHz Crystal — W5100S PHY Reference
+
+The W5100S integrated Ethernet PHY requires a 25 MHz reference crystal. Same 3.2 × 2.5 mm SMD package recommended for consistency.
+
+---
+
+## Ethernet Interface
+
+### Integrated MagJack (e.g. HR911105A)
+
+An integrated RJ45 connector with built-in magnetics and link/activity LEDs. Choosing an integrated MagJack over discrete transformer + RJ45 reduces component count, eliminates transformer placement constraints, and ensures the common-mode choke is matched to the connector.
+
+---
+
+## Ground and Power Planes
+
+- **Single solid GND plane** — do not split signal and power ground. At 24–27 MHz digital switching, return currents flow under their signal traces; splitting the plane forces longer return paths and increases EMI.
+- **SP1 pin 2 (shield ground)** — connect to GND plane near the connector via a 0 Ω resistor or 100 nF capacitor to allow a break point if the GameCube chassis ground introduces a ground loop during bring-up.
+- **SP1 pin 5 (12 V)** — power input to buck converter. Do not connect to any FPGA I/O.
+- **Buck converter layout** — keep the switching loop (input cap → switch node → inductor → output cap) compact and away from EXI and Ethernet signal traces.
+- **Decoupling** — 100 nF ceramic (0402) at every power pin; 100 µF bulk cap near the SP1 connector on the 3.3 V rail.

+# RGB LED Status Panel
+
+## Background
+
+The `StatusPanel` module (`exi_bba/status_panel.py`) exposes 5 logical LED outputs:
+
+| Index | Signal | Meaning |
+|-------|--------|---------|
+| `led[0]` | heartbeat | ~1.4 Hz blink — clock alive, bitstream loaded |
+| `led[1]` | exi_active | EXI transaction in progress (GC is talking) |
+| `led[2]` | rx_act | Ethernet frame received |
+| `led[3]` | tx_act | Ethernet frame transmitted |
+| `led[4]` | ready | Ethernet initialisation complete |
+
+The iCEbreaker board has **two discrete LEDs** (LEDR pin 11, LEDG pin 37) and **one RGB LED** (pins 39/40/41). Together they cover all 5 signals with no overlap.
+
+---
+
+## Pin Mapping
+
+| Physical LED | iCE40 pin | Signal | Colour |
+|-------------|-----------|--------|--------|
+| LEDG (discrete green) | 37 | `led[0]` heartbeat | green |
+| LEDR (discrete red) | 11 | `led[1]` EXI activity | red |
+| RGB element 0 | 41 | `led[2]` rx activity | red |
+| RGB element 1 | 40 | `led[3]` tx activity | green |
+| RGB element 2 | 39 | `led[4]` ready | blue |
+
+The RGB colour-to-element mapping (RGB0/RGB1/RGB2 → R/G/B) should be verified against the iCEbreaker schematic at hardware bring-up. It is a one-line change in `synth.py` if elements are swapped.
+
+---
+
+## Implementation
+
+The iCEbreaker RGB LED has **no series current-limiting resistors** on the board. It relies on the iCE40UP5K's on-chip `SB_RGBA_DRV` primitive, which is a dedicated open-drain current-source driver with built-in PWM support. The RGB pins (39/40/41) cannot be driven safely as regular LVCMOS outputs for this reason.
+
+`SB_RGBA_DRV` outputs connect directly to the physical RGB pad locations — nextpnr places the primitive automatically without requiring PCF pin constraints. The platform resource system (`platform.request()`) is therefore **not used** for the RGB pins; only the two discrete LEDs are declared as platform resources.
+
+The instance is added in `exi_bba/synth.py` inside the `self._status_panel` block of `BBATopSynth.elaborate()`:
+
+```python
+m.submodules.rgb_drv = Instance("SB_RGBA_DRV",
+    p_CURRENT_MODE="0b1",       # half-current mode
+    p_RGB0_CURRENT="0b000001",  # ~4 mA red
+    p_RGB1_CURRENT="0b000001",  # ~4 mA green
+    p_RGB2_CURRENT="0b000001",  # ~4 mA blue
+    i_CURREN=Const(1, 1),
+    i_RGBLEDEN=Const(1, 1),
+    i_RGB0PWM=led[2],           # rx activity
+    i_RGB1PWM=led[3],           # tx activity
+    i_RGB2PWM=led[4],           # ready
+    o_RGB0=Signal(name="rgb_r"),
+    o_RGB1=Signal(name="rgb_g"),
+    o_RGB2=Signal(name="rgb_b"),
+)
+```
+
+The output signals (`rgb_r/g/b`) are unconnected in the Amaranth netlist. yosys preserves `SB_RGBA_DRV` as a known iCE40 hardware primitive regardless, and nextpnr routes its outputs to the physical RGB pads.
+
+Current is set to the lowest available setting (4 mA half-current) — visible as a status indicator without being distracting.
+
+---
+
+## No Changes Required in StatusPanel
+
+The `StatusPanel` module already outputs all 5 signals on `self.led[0:5]`. Only `synth.py` changed — adding the `SB_RGBA_DRV` instance and updating the comment block.
