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
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
L = Left
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.
