STM6601CQ2BDM6F from STMicroelectronics, in a TDFN-12(2x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Power supply input that is monitored during startup and normal operation for sufficient voltage; decouple it to ground with a 0.1 µF capacitor placed as close to the device as possible. |
| 2 | SR | input | Smart Reset button input with a factory-trimmed voltage detector and ±8 kV HBM ESD protection; it is active low with an optional 100 kΩ pull-up and must not be permanently grounded. |
| 3 | VREF | power_out | Precise 1.5 V voltage reference output with 1% accuracy that is disabled in standby; a 1 µF capacitor is mandatory on this pin even when VREF is unused. |
| 4 | PSHOLD | input | Power-supply hold input with a factory-trimmed voltage detector that confirms proper power-up and, when driven low during normal operation, deasserts the enable output; an internal pull-down is active during startup. |
| 5 | CSRD | passive | Smart Reset delay input where a capacitor to ground sets the additional delay tSRD (charged with ISRD), a low-ESR ceramic is recommended, and the pin is left open if no capacitor is used. |
| 6 | PB | input | Power-on push-button input with a factory-trimmed voltage detector and ±8 kV HBM ESD protection that must be switched to GND and has an internal 100 kΩ pull-up. |
| 7 | VCCLO | output | Active-low open-drain high-threshold detection output that is low when VCC is below VTH+ at power-up or during undervoltage in normal operation, requires a pull-up (10 kΩ typical), and is floating in standby. |
| 8 | PBOUT | output | Active-low open-drain output that reflects the PB push-button state after tDEBOUNCE, ignores PB during undervoltage, and requires a pull-up (10 kΩ typical). |
| 9 | EN or EN | output | Push-pull enable output that asserts after a valid push-button turn-on with VCC above VTH+ and releases if the push-button is released before PSHOLD is high, PSHOLD is driven low, undervoltage persists too long, or a long push is detected; for this ordering code (option C) it is active high EN. |
| 10 | RST | output | Active-low open-drain reset output that is pulled low for tREC (240 ms min.) during startup and requires a pull-up (10 kΩ typical); on this variant a long push deasserts EN instead of asserting RST. |
| 11 | INT | output | Active-low open-drain interrupt output that is driven low for at least tINT_Min on a push-button press longer than tDEBOUNCE or on VCC undervoltage, held high during power-up, and requires a pull-up (10 kΩ typical). |
| 12 | GND | power_in | Ground reference for the device. |
| 13 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
