SAA3010T
12.5.1. Description
The SAA3010 is intended as a general purpose (RC-5) infrared remote control system for use where a low
voltage supply and a large debounce time are expected. The device can generate 2048 different commands
and utilizes a keyboard with a single pole switch for each key. The commands are arranged so that 32
systems can be addressed, each system containing 64 different commands. The circuit response to legal
(one key pressed at a time) and illegal (more than one key pressed at a time) keyboard operation is specified
in the section
Keyboard operation
