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.

Note: An Auto Shut-Off mechanism is built-in according to Toy Safety Requirement and effective during over-current
situation in motor driver. The active high input applying to this Auto Shut-Off pin will turn off the motor. (VT pin,
when unused, has to be connected to ground. The transfer point =1.4V)

N = No used code
F、B、T、R、L、F1、N、N、F2 all can have two date format, ”F1” or ”F0”,
“F1” means the function is in effect, and “F0” means not.
- parity code = for parity check

(2) The UTC RCR6C have built in a zener diode, so you must add a resistance between POWER and IC’s VDD pin,
like the R6 of UTC RCR6C application circuit.

UTC RCT6 output pin (SO) has an inverted phase with UTC RCR6C input (SI). If UTC RCT6 is connected without
using a RF module, an inverter has to be inserted between this 2 pins.
UTC assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or
other parameters) listed in products specifications of any and all UTC products described or contained
herein. UTC products are not designed for use in life support appliances, devices or systems where
malfunction of these products can be reasonably expected to result in personal injury. Reproduction in
