TX-5B/RX-5B
FUNCTION DESCRIPTION
The TX-5B/RX-5B are a pair of CMOS LSIs designed for remote controlled car applications. The TX-5B/RX-5B
have nine control keys controlling the motions (i.e. forward, backward, rightward, leftward, and trigger1--trigger4
functions and the turbo function) of the remote controlled car.
1. OVER-CURRENT PROTECTION
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)
2. DATA FORMAT
F1="1"
500Hz, 3/4 duty
F0="0"
500Hz, 1/4 duty
3. CODING METHOD
3.1 when a trigger pin is triggered, its data code will correspond to the data format of "F1", while the remaining pins
will have the data format of "F0".
3.2. Data string: start code + data code +parity code + end code
start code = F1 F1 F1 F1 F0
data code =
F

F = Forward
B = Backward
T = Turbo
R = Right
L = Left
F1 = Function1
F2 = Function2
F3 = Function3
F4 = Function4
parity code = for parity check
end code = for (latch data)
* Data code can be any combination of F,B,T,R,L,F1,F2,F3,F4 except for F&B, R&L, F3&F4.
