Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VOUT | output | Regulated supply output that switches between VCC and VBAT based on VSO threshold, sourcing up to 75 mA with VCC - 0.15 V typical drop. |+| 2 | VCC | power_in | Main supply voltage input operating from 1.0 to 5.5 V; device asserts RST when VCC falls below VRST threshold (2.925 V typical for STM704S). |+| 3 | VSS | power_in | Ground reference and common return path for all device currents. |+| 4 | PFI | input | Power-fail input compared to VPFI threshold (1.237 V typical) and VSW (2.4 V), causing PFO to go low when below either voltage. |+| 5 | PFO | output | Push-pull power-fail output that goes low within 2 µs when PFI < 1.237 V typical or VCC < 2.4 V, providing early power-failure warning. |+| 6 | MR | input | Active-low manual reset input with 40 kΩ internal pull-up that asserts RST for minimum 20 ns pulse width and holds reset for trec (200 ms typical) after release. |+| 7 | RST | output | Push-pull active-low reset output that pulses low for trec (200 ms typical) when VCC falls below VRST, and is guaranteed valid down to VCC = 1.0 V with backup battery. |+| 8 | VBAT | power_in | Backup battery supply input supporting automatic switchover at VSO (2.4 V); may exceed VCC; supplies external LPSRAM with 0.4 µA quiescent current during battery backup mode. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SO-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `STM704SM6F`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)+- 3D model files: `stm704sm6f-etched.step` / `stm704sm6f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stm704sm6f.step` / `stm704sm6f.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588952128400871424) (42 pp, sha256 `7b0e1b14da4b9b31`, retrieved 2026-09-23, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5` (agreed), guards: pin_guards 0.1: passed.
