6V ■ Interrupt output pin ■ Reset input pin ■ Wake up feature on each I/O ■ Up to 2 devices sharing the same bus (1 address line) ■ <1µA suspend current Application ■ Portable media player, Game console ■ Mobile phone, Smart phone STMPE801 8-bit port expander Xpander logic QFN16L SO-16 Description The STMPE801 is a GPIO (General Purpose Input / Output) port expander able to interface a main digital ASIC via the two-line bidirectional bus (I2C); separate GPIO Expander IC is often used in Mobile-Multimedia platforms to solve the problems of the limited amounts of GPIOs usually available on the Digital Engine.
The STMPE801 offers great flexibility as each I/Os is configurable as input, output.
This device has been designed very low quiescent current, and includes wake up feature for each I/O, to optimize the power consumption of the IC.
