STM708TM6F from STMicroelectronics, in a SO-8. 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 | MR | input | Active-low push-button reset input with internal 40 kΩ pull-up; logic low asserts reset output and remains asserted for trec after MR returns high; TTL/CMOS compatible. |
| 2 | VCC | power_in | Positive supply voltage; operating range 1.0 V to 5.5 V with typical supply current 40 µA at VCC < 5.5 V. |
| 3 | VSS | power_in | Ground return potential. |
| 4 | PFI | input | Power-fail input for threshold comparison at VPFI (1.20 V to 1.30 V typical 1.25 V); when PFI falls below VPFI, power-fail output PFO goes low; connect to ground if unused. |
| 5 | PFO | output | Push-pull power-fail output; goes low when PFI < VPFI threshold; provides early warning of impending power supply failure; leave open if unused. |
| 6 | NC | unconnected | No connect; leave unconnected. |
| 7 | RST | output | Active-low reset output (push-pull); pulses low for trec (140-280 ms) when triggered by VCC falling below VRST (3.00-3.15 V) or MR assertion; guaranteed valid down to VCC = 1.0 V. |
| 8 | RST | output | Active-high reset output (push-pull); complementary to RST pin 7 with opposite polarity; pulses high for trec when triggered by power-fail or MR release. |
