STMPE801 Datasheet (ST Microelectronics) - 8-bit port expander Xpander logic

STMPE801, 8-bit port expander Xpander logic

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
