Description

The AW9523 is a twist on the common I2C expander:
  • It has 16 I/O pins, that'll double most boards' pin count
  • Four I2C address options, so you can connect 4 expanders to one bus
  • Each pin can be an input or an output
  • IRQ output can alert you when input pins change value
  • This chip does not support internal pull-ups or pull-downs, you will need to add an external resistor if you need one
  • However, it does have 8-bit linear constant-current LED dimming support so you can connect LEDs without resistors and have great looking dimming without PWM
  • The first 8 pins can be configured as open drain (as a group)

AW9523 Features:
  • 16 multi-function I/O, each for LED drive (current-source dimming) or GPIO mode
  • 256 steps linear dimming in LED drive mode
  • Any GPIO can be configured as an input or an output independently
  • Support interrupt, 8us deglitch, low-level active
  • Standard I2C interface, AD1/AD0 select I2C device address
  • SDA, SCL, SHDN, and all GPIO can accept in 1.8V logic input
  • ESD protection: ±4000V HBM (MIL-STD-883H Method 3015.8 standard)
  • Latch-up :±450mA( JEDEC STANDARD NO.78C SEPTEMBER 2010 standard)
  • Supply shutdown function, low-level active
  • 2.5V~5.5V power supply
  • I2C address default 0x58 (can be 0x59, 0x5A or 0x5B)
