STM6780TWB6F from STMicroelectronics, in a SOT-23-6. 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 | RST | output | Active-low push-pull reset output driven low when VCC1 falls below programmed threshold (1.58-4.63V selectable), RSTIN drops below 0.626V internal reference, or MR input goes low; remains low for minimum 140ms typical (8.8-280ms depending on code) after all monitored supplies recover above thresholds and MR returns high. |
| 2 | VSS | power_in | Ground connection; return path for all supply currents and voltage reference for on-chip monitoring comparators and timing circuits. |
| 3 | MR | input | Active-low push-button manual reset input with internal 50kΩ pull-up resistor to VCC1; minimum pulse width 1µs when MRC left open, or 6µs minimum when MRC connected to capacitor; MR-to-RST propagation delay 200ns typical. |
| 4 | MRC | input | Manual reset delay input; connect to VSS through external capacitor to program manual reset delay from 6µs (open) to several seconds (e.g., 4s with 3.3µF); capacitor value determines timing of reset response after MR button press. |
| 5 | RSTIN | input | High-impedance tertiary supply monitor input; RST driven low when voltage at this pin drops below 0.626V internal reference (set with external resistor divider); input current ±25nA; RSTIN-to-RST propagation delay 22µs typical; threshold hysteresis 3mV. |
| 6 | VCC1 | power_in | Primary supply voltage input (operating range 0.8-5.5V); monitored by on-chip comparator with factory-programmed reset threshold (selectable 1.58-4.63V for STM6780); supplies power to MR internal pull-up resistor and RST push-pull output driver. |
