RCT6
CMOS IC
REMOTE CONTROLLER WITH
SEVEN FUNCTIONS
DESCRIPTION
The UTC RCT6 is a pair of CMOS LSIs designed for remote
controlled car applications. The UTC RCT6 have seven control keys
controlling the motions (i.e. forward, backward, rightward, leftward,
two function keys, and the turbo function) of the remote controlled
car. UTC RCT6 have Forward (Backward) combined with the turbo
application. The UTC RCT6 is the sending electric circuit.
DIP-16

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)

CODING METHOD
The data string that UTC RCT6 receives is below:
Data string: start code + data code + parity code + end code
- start code = F1 F1 F1 F1 F0
- data code =

F = Forward
R = Right
B = Backward
L = Left
T = Turbo
F1 = Function 1
F2 = Function 2
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
- end code = for (latch data)
* Data code can be any combination of F, B, T, R, L, F1, F2, except for F & B, and R & L.

TEST CIRCUIT
Fosc for UTC RCT6 ≌ 128KHz
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
whole or in part is prohibited without the prior written consent of the copyright owner. The information
presented in this document does not form part of any quotation or contract, is believed to be accurate
