TX•6B/RX•6B
FUNCTION DESCRIPTION
The TX•6B/RX•6B are a pair of CMOS LSIs designed for remote controlled car applications. The TX•6B/RX•6B
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.
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
500Hz, 3/4 duty
500Hz, 1/4 duty
F1="1"
F0="0"
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
B
T
R
L
F1
N
N
F2
F = Forward
L = Left
B = Backward
F1 = Function1
T = Turbo
R = Right
F2 = Function2
N = No used code
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, R&L.
