SD6830
4BIT MICROCONTROLLER
1. Description
SD6830 is a remote control transmitter, consists of the optimized 4-bit CPU with ROM and
RAM. It contains power-on reset, watchdog timer and carrier frequency generator. The
SD6830 provide a various carrier frequency for encoding output of key matrix and has
built-in transistor to drive infrared LED. The SD6830 is supported with a software
development tool, which allows code development in a PC environment. It allows the user
to simulate the SD6830 on an instruction level.
