1 / 27 page  This is information on a product in full production. February 2013 Doc ID 16938 Rev 3 1/27 27 STMPE1600 16-bit port expander with ultra-low power consumption Xpander Logic™ Datasheet −production data Features ■ 16 GPIOs which default to 16 inputs on power- up ■ Serial I2C interface (0 to 400 kHz) to the host with noise filter ■ Operating voltage 1.65 V - 3.6 V ■ I/O voltage 1.65 V - 3.6 V ■ Interrupt output pin ■ Internal power-on-reset ■ Wakeup feature on each I/O ■ Up to 8 devices sharing the same bus ■ (3 address pins) ■ 8 mA current drive/sink on each GPIO at 3.3 V ■ < 1µA suspend current ■ ESD protection exceeds 2 KV HBM per JESD22-A114 ■ Latch-up testing exceeding 100 mA ■ Package: QFN24 (4 x 4 mm with 0.5 mm pitch) Applications ■ Portable media players ■ Game consoles ■ Mobile phones ■ Smart phones Description The STMPE1600 is a GPIO (general purpose input/output) port expander able to interface a main digital ASIC via the two-line bidirectional bus (I2C). A separate GPIO expander IC is often used in mobile multimedia platforms to solve the problems of the limited amount of GPIOs typically available on the digital engine. I/O expanders provide a simple solution when additional I/O are needed for several interface functions such as sensors, pushbuttons, LEDs, fans, etc. The STMPE1600 offers great flexibility as each I/O can be configured as input or output. The device has been designed with very low quiescent current and includes a wakeup feature for each I/O, to optimize the power consumption of the device. QFN24 (4 x 4 mm) Table 1.
