UNISONIC TECHNOLOGIES CO., LTD RCR6C Preliminary CMOS IC REMOTE CONTROLLER WITH SEVEN FUNCTIONS DESCRIPTION The UTC RCR6C is a CMOS LSI and designed as receiver that complement to UTC RCT6 for remote controlled car applications. It provide seven control keys controlling the motions, which are forward, backward, rightward, leftward, two function keys, and the turbo function, of the remote controlled car. UTC RCR6C have Forward (Backward) combined with the turbo application. During normal operation without Turbo, Forward (Backward) output from UTC RCT6 sends a 60Hz signal. When Forward (Backward) and Turbo are both in effect, the output signal becomes completely high. FEATURES * Operating voltage range: 2.4V~4.5V * RCR6C-A built-in 3.6V ZENER RCR6C-B built-in 4.2V ZENER RCR6C-C built-in 5.0V ZENER * Few external components needed * 7-function remote controller controlling Forward/ Backward/ Turbo/ Right-turn/ Left turn/ two function keys * Complement to UTC RCT6.
