PI4IOE5V6416 16-Bit General Purpose I²C-Bus I

Diodes’ PI4IOE5V6416 16-bit general purpose I/O expander provides remote I/O expansion for most microcontroller families via the I2C-bus interface. It provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. In battery-powered mobile applications for interfacing to sensors, pushbuttons, and keypads, it operates from 1.65 V to 5.5 V on the GPIO-port side and 1.65 V to 5.5 V on the SDA/SCL side (I2C-bus interface). This allows the PI4IOE5V6416 to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side where supply levels are reducing to conserve power. The PI4IOE5V6416 is available in the industry standard TSSOP-24 and TQFN-24 packages.

  • Low operation power supply voltage from 1.65 V to 5.5 V supports a new generation of low power supply microprocessors and microcontrollers
  • Bidirectional voltage level translation and GPIO expansion
    • Simplified interconnection between processor running at one voltage level to I/O devices operating at a different (usually higher) voltage level
  • Fully compatible with I2C standard mode and I2C fast mode (up to 400 KBit/s operation)
  • Wise I/O programming features:
    • Programmable output drive strength
    • Latchable inputs
      • Programmable pull-up/pull-down resistors
    • Maskable interrupt
      • Programmable open-drain or push-pull outputs
  • Servers
  • Networking
  • Telecom
  • Mobile applications
