  • 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.

    Key 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)
