Présentation
Description
- 16 programmable I/O pins (configurable as inputs or outputs).
- Interrupt output for monitoring input changes.
- Low standby current (suitable for power-sensitive applications).
- Wide voltage range (1.65V to 5.5V), supporting mixed-voltage systems.
- 400 kHz I²C compatibility for fast communication.
Commonly used in consumer electronics, industrial controls, and IoT devices, it reduces MCU pin usage while adding flexibility. The T2 suffix indicates tape-and-reel packaging.
For detailed specs, refer to the datasheet.
