STMPE1600QTR STMicroelectronics

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 2 Serial I C 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 QFN24 Internal power-on-reset (4 x 4 mm) Wakeup feature on each I/O Up to 8 devices sharing the same bus (3 address pins) Description 8 mA current drive/sink on each GPIO at 3.3 V The STMPE1600 is a GPIO (general purpose < 1A suspend current input/output) port expander able to interface a ESD protection exceeds 2 KV HBM per main digital ASIC via the two-line bidirectional bus JESD22-A114 (I2C). A separate GPIO expander IC is often used Latch-up testing exceeding 100 mA in mobile multimedia platforms to solve the problems of the limited amount of GPIOs typically Package: QFN24 (4 x 4 mm with 0.5 mm pitch) available on the digital engine. I/O expanders provide a simple solution when Applications additional I/O are needed for several interface Portable media players functions such as sensors, pushbuttons, LEDs, fans, etc. Game consoles The STMPE1600 offers great flexibility as each Mobile phones I/O can be configured as input or output. The Smart phones 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. Table 1.
