概述
The TPT29555A is a 16-bit GPIO expander with interruption and weak pull-up resistors for I2C-bus applications. The power supplier voltage range is from 1.65 V to 5.5 V, allowing the TPT29555A to interconnect with 1.8-V microcontrollers.
The TPT29555A contains the register set of two pairs of 8-bit Configuration, Input, Output, and Polarity Inversion registers. The open-drain interrupt (INT) output is changeable when any input state changes from its related register state and is used to indicate the system master that an input state has changed. INT can be connected to the interrupt input of a microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I2C-bus. Thus, the TPT29555A can remain a simple slave device. The poweron reset sets the registers to their default values and initializes the device state machine.
All input/output pins have internal weak pull-up resistors to remove external components. Three hardware pins (A0, A1, A2) select the fixed I2C-bus address and allow up to eight devices to share the same I2C-bus.
TPT29555A is available in TSSOP24 and QFN24 packages and is characterized from −40°C to +125°C.
