Diodes Incorporated PI4IOE5V6534Q 34-bit I/O Expander

Diodes Incorporated PI4IOE5V6534Q 34-bit I/O Expander provides remote I/O expansion for most microcontroller families via the FC-bus interface. The PI4IOE5V6534Q is a simple solution when additional I/Os are needed while keeping interconnections to a minimum. The expander IC operates from 1.65V to 5.5V on the GPIO-port side and 0.8V to 3.6V on the SDA/SCL side. This allows the PI4IOE5V6534Q to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power.

Features

  • Operating power supply voltage range of 8V to 3.6V on the I2C-bus side
  • Allows bidirectional voltage-level translation and GPIO expansion between:
  • 8V to 3.6V SCL/SDA and 1.8/2.5/3.3/5.5V Port
  • Compliant with the I2C-bus Fast-mode plus, Fast-mode, and Standard mode
  • I/O Features
  • Output port configurations: bank selectable or pin selectable push-pull or open-drain output stages
  • Interrupt status: read-only register identifies the source of an interrupt
  • Low standby current consumption
  • 2μA typical at 3.3V VDD(P)
  • 5V tolerant I/O ports and 3.6V tolerant I2C-bus pins
  • 1MHz Fast-mode Plus I2C-bus interface
  • Power-on reset
  • Active LOW open-drain interrupt output (INT)
  • Active LOW reset input (RESET)
  • Latch-up tested (exceeds 100mA)
  • Latched Outputs for Directly Driving LEDs
  • AEC-Q100 (Grade 2)
  • Totally Lead-Free & Fully RoHS Compliant 
  • Halogen and Antimony Free "Green" Device 
  • The PI4IOE5V6534Q is suitable for automotive applications requiring specific change control; this part is AEC-Q100 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities
  • Packaging (Pb-free & Green)
  • 46-Pin, Wettable TQFN 4.5x6.5mm (ZLW)
  • I/O programming features
    • Output drive strength
      • Four programmable drive strengths to reduce rise and fall times in low-capacitance applications
    • Input latch
      • Input Port register values changes are kept until the Input Port register is read
    • Pull-up/pull-down enable
      • Floating input or pull-up/pull-down resistor enable
    • Pull-up/pull-down selection
      • 100k-ohm pull-up/pull-down resistor selection
    • Interrupt mask
      • Mask prevents the generation of the interrupt when input changes state to prevent spurious interrupts
    • Interrupt edge specification on a bit-by-bit basis
    • Interrupt individual clear without disturbing other events
    • Read all interrupt events without clear
    • Switch debounce hardware
    • General call software reset
    • I2C software Device ID function
