TX-5B

Silan Semiconductors REMOTE CONTROLLER WITH SEVEN FUNCTIONS DESCRIPTION The TX-5B/RX-5B are a pair of CMOS LSIs designed for remote controlled car applications. They have nine control keys controlling the motions (i.e. forward, backward, rightward, leftward, trigger 1-trigger 4 functions and the turbo function) of the remote controlled car. The TX-5B is housed in DIP-16 package, and the RX-5B is housed in DIP-22 package. TX-5B/RX-5B DIP-16 DIP-22 FEATURES * Wide operating voltage range TX-5B: (VDD=2.2~12.0V) RX-5B: (VDD=3.0~12.0V) * Very Low stand-by current for TX-5B * Auto-power-off function for TX-5B * Few external components are needed * Built-in 3.6V zener for RX-5B * 9 functions remote controller controlling: forward,backward, right, left, turbo, trigger 1-- trigger 4 functions ORDERING INFORMATION Part No. TX-5B/RX-5B Package DIP-16-300-2.54 DIP-22-400-2.54 PIN CONFIGURATION VO2 GND RIGHT TEST GND BACKWARD FORWARD TURBO SC F34 1 2 3 4 5 6 7 8 9 10 11 22 21 20 19 18 VI2 VO1 VI1 VDD TURBO F3 FORWAR F4 BACKWAR LRTD LDB 1 2 3 4 5 6 7 8 16 15 14 13 LEFT SI F1 OSCI OSCI OSCO OSCO F1 PC RIGHT VDD F2 SO LEFT F2 VT RDB RX-5B 17 16 15 14 13 12 TX-5B 12 11 10 9 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2002.03.26 1 Silan Semiconductors BLOCK DIAGRAM TEST TX-5B/RX-5B 2 OSCI 14 Oscillator 13 Timing Generator OSCO RIGHT 1 16 6 5 4 Latch Circuit Encoding Circuit Logic 11 VDD LEFT 12 PC 10 SO 7 SC TURBO FORWARD BACKWARD 15 F1 9 F2 8 F34 3 GND TX-5B Block Diagram OSCI 4 Oscillator Timing Generator Counter 19 VDD OSCO 5 3 21 20 12 13 11 10 22 1 2 GND Control Logic Latch Circuit AMP Decoding Circuit SI VO1 VI1 PLA 7 RIGHT 9 LEFT LDB LRTD RDB VT 18 TURBO 14 BACKWARD 16 FORWARD 6 8 F1 F2 F3 F4 VI2 VO2 17 15 RX-5B Block Diagram HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2002.03.26 2 Silan Semiconductors ABSOLUTE MAXIMUM RATINGS Characteristic DC Supply Voltage Input/Output Voltage Operating Temperature Storage Temperature TX-5B/RX-5B Symbol VDD VIN,VOUT Topr Tstg Value 0.3 ~ 5.0 GND-0.2V ~ VDD+0.2V -10 ~ +60 -25~+125 Unit V V °C °C COMMENT Never allow a stress to exceed the values listed under "Absolute Maximum Ratings", otherwise the device would suffer from a permanent damage. Nor is a stress at the listed value be allowed to persist over a period, since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device, if not causing a damage thereof.

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 B T R L F1 F3 F4 F2 F = Forward F1 = Function1 B = Backward F2 = Function2 T = Turbo F3 = Function3 R = Right F4 = Function4 L = Left 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.
