Description

The PCA9671 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus (Fm+) family.

Key Features

  • 1 MHz I2C-bus interface
  • pliant with the I2C-bus Fast-mode and Standard-mode
  • SDA with 30 mA sink capability for 4000 pF buses
  • 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os
  • 16-bit remote I/O pins that default to inputs at power-up
  • Latched outputs with 25 mA sink capability for directly driving LEDs
  • Total package sink capability of 400 mA
  • Active LOW reset input
  • 64 programmable slave addresses using 3 address pins
  • Readable device ID (manufacturer, device type, and revision)

Applications

  • LED signs and displays
