... 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 ...

... General call – Start/Restart/Stop – Address STMPE1600 devices via I Start condition A Start condition is identified by a falling edge of SDA while SCL is stable at high state. A Start condition must precede any data/command transfer. The device continuously monitors for a Start condition and will not respond to any transaction unless one is encountered. ...

... A general call address is a transaction with the slave address of 0x00 and R When a general call address is made, the device responds to this transaction with an acknowledgement and behaves as a slave-receiver mode. The meaning of a general call address is defined in the second byte sent by the master-transmitter. 10/26 Doc ID 16938 Rev 1 STMPE1600 ...

... GPIO controller 8 GPIO controller A total of 16 GPIOs are available in the STMPE1600 port expander IC. The GPIO controller contains the registers that allow the host system to configure each of the pins into either a GPIO (input or output), or into one of the alternate functions. Unused GPIOs should be configured as outputs to minimize the power consumption ...

... The STMPE1600 operates with a single power supply VCC that ranges from 1.65V to 3.6V. The GPIO remains valid until the V reset. 9.2 Reset The STMPE1600 is equipped with an internal POR circuit that holds the device in reset state, until the the duration when reset pin is asserted, all GPIO are reset and default to input states. 10 ...
