IO Expander Breakout - 16 Output - I2C

Are you low on I/O? No problem! The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals, so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.

Quick Spec

  • Enable Direct Level Shifting Between I/O Banks and Host Controller
  • 5.5V Tolerant I/Os, Up to 15mA Output Sink on All I/Os
  • Integrated LED Driver with Intensity Control
  • On-Chip Keypad Scanning Engine Supports Up to 8x8 Matrix (64 Keys)
  • 16 Channels of True Bi-directional Style I/O
  • 400kHz I2C Compatible Slave Interface
