UNISONIC TECHNOLOGIES CO., LTD RCR5 Preliminary REMOTE CONTROLLER WITH NINE FUNCTIONS CMOS IC  DESCRIPTION The UTC RCR5 is a CMOS LSI and designed as receiver that complement to UTC RCT5 for remote controlled car applications. It provide nine control keys controlling the motions, which are forward, backward, rightward, leftward, four function keys, and the turbo function, of the remote controlled car. UTC RCR5 have Forward (Backward) combined with the turbo application. During normal operation without Turbo, Forward (Backward) output from UTC RCR5 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~4.0V * Built-in 4.2V zener * Few external components needed * 9-function remote controller controlling Forward/ Backward/ Turbo/ Right-turn/ Left turn/ four function keys * Complement to UTC RCT5.  ORDERING INFORMATION Ordering Number Lead Free Halogen Free RCR5L-D22-T RCR5G-D22-T Package DIP-22 DIP-22 Packing Tube  MARKING www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd 1 of 8 QW-R112-003.a RCR5  PIN CONFIGURATIONS Preliminary CMOS IC  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 PIN NAME VO2 GND SI OSCI OSCO F1 RIGHT F2 LEFT DESCRIPTION Inverter 2 output pin for signal amplify Ground Input pin of the encoding signal Oscillator input pin Oscillator output pin F1 function output pin Rightward output pin F2 function output pin Leftward output pin VT Auto Shut-OFF input pin.
