General Description

The TPT29555 is a 16-bit GPIO expander with interrupt and weak pull-up resistors for I2C-bus applications.

The power supplier voltage range is from 1.65 V to 5.5 V that allows the TPT29555 to interconnect with 1.8-V microcontrollers.

The TPT29555 contains the register set of two pairs of 8-bit Configuration, Input, Output, and Polarity Inversion registers.

Key Features

  • I2C-bus to 16-bit GPIO expander.
  • Operating power supply voltage from 1.65 V to 5.5 V.
  • Low standby current consumption:.
  • 3.0 μA (typical at 5 V VCC).
  • 1.5 μA (typical at 3.3 V VCC).
  • 400 kHz Fast-mode I2C-bus.
  • 5 V tolerant I/Os.
  • Open-drain active LOW interrupt output (INT).
  • Configurable Slave Address with 3 Address Pins.
  • Internal power-on reset.
  • Power-up with all channels configured as inputs with weak pull-up resistors.
  • Latch-Up.
