ECE1117 - Multi-Function BC-Link/SMBus Companion Device

General Description

The ECE1117 is a 48-pin 3.3V multi-function companion device.

The ECE1117 communicates with an upstream host via BC-Link or SMBus.

The ECE1117 is typically mounted in the keyboard assembly.

Key Features

  • Microchip BC-Link™ Slave Interface to Host EC - 3-pin point-to-point communication link to Embedded Controller.
  • Optional SMBus Slave Interface to Host EC - BC-Link/SMBus protocol autodetect - Strap pin selects between two slave addresses at POR - Dynamically programmed slave address after POR.
  • Keyboard Scan Matrix - Up to 19x8 Keyboard Scan Matrix.
  • LED Output Pins - 7 LED Output Pins - 4 with 20mA current sink - 3 with 4mA current sink - Multiple Clock Rates.
