STMPE801 Datasheet | STMicroelectronics

Features - 8 GPIO - Operating voltage 1.65V - 3.6V - I/O voltage 1.65V-3.6V - 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 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. Table 1.
