Fonctionnalités et applications

The PCA9539; PCA9539R is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.

The PCA9539; PCA9539R consists of two 8-bit configuration (input or output selection), input, output and polarity inversion (active HIGH or active LOW operation) registers. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the read register can be inverted with the Polarity inversion register. All registers can be read by the system master.

Features:

  • 16-bit I2C-bus GPIO with interrupt and reset
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5 V tolerant I/Os
  • Polarity inversion register
  • Active LOW interrupt output
  • Active LOW reset input
  • Low standby current
  • Noise filter on SCL/SDA inputs
  • No glitch on power-up
  • Internal power-on reset
  • 16 I/O pins which default to 16 inputs
  • 0 Hz to 400 kHz clock frequency
