Product details

Device identity and threshold selection

The STM6321LWY6F: This threshold is suitable for 5V supply rails — the part asserts reset when VCC drops below 4.63V, holding the system in reset until the supply recovers and the 140ms minimum timeout elapses. The reset output is configurable as active high or active low, and the driver can be open drain or push-pull, giving flexibility to interface with different logic families or shared reset buses.

Package and temperature grade

Housed in a SOT-23-5 package (SC-74A, SOT-753), the device is surface-mount and occupies minimal board area — suitable for space-constrained designs.
