STM6315RDW13F

STMicroelectronics · Supervisor and Reset ICs · SOT-143

STM6315RDW13F from STMicroelectronics, in a SOT-143. 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 VSS power_in Ground reference for the device. Connect to the system ground plane; a 0.1 µF bypass capacitor on VCC referenced to VSS is recommended for transient immunity.
2 RST output Active-low, open-drain reset output. Requires an external pull-up (10 kΩ typical) to any supply up to 6 V, and may be pulled above VCC. Asserts low whenever VCC is below the reset threshold or MR is low, and remains low for the reset time-out period (trec) after the condition clears. Guaranteed valid down to VCC = 1.0 V.
3 MR input Active-low manual reset input. Asserts RST while held low and for trec after release. Has an internal ~63 kΩ pull-up so it may be left open if unused. Accepts TTL/CMOS logic or open-drain drive; a simple pushbutton to VSS provides a debounced manual reset without external components.
4 VCC power_in Positive supply input, monitored against the factory-trimmed reset threshold (2.63/2.93/3.08/4.38/4.63 V depending on ordering suffix). Typical ICC ≈ 1.5 µA. Decouple with a 0.1 µF capacitor as close to the pin as possible.
