Silan Semiconductors TX-5B/RX-5B REMOTE CONTROLLER WITH SEVEN FUNCTIONS DESCRIPTION The TX-5B/RX-5B are a pair of CMOS LSIs designed for remote DIP-16 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. DIP-22 FEATURES * Wide operating voltage range TX-5B: (VDD=2.2~12.0V) RX-5B: (VDD=3.0~12.0V) ORDERING INFORMATION * Very Low stand-by current for TX-5B Part No. * Auto-power-off function for TX-5B * Few external components are needed Package DIP-16-300-2.54 TX-5B/RX-5B DIP-22-400-2.54 * Built-in 3.6V zener for RX-5B * 9 functions remote controller controlling: forward,backward, right, left, turbo, trigger 1-- trigger 4 functions PIN CONFIGURATION RIGHT 1 16 LEFT TEST 2 15 F1 GND 3 14 OSCI BACKWARD 4 13 OSCO FORWARD 5 TX-5B 12 TURBO 6 11 VDD SC 7 10 SO F34 8 9 F2 VO2 1 22 VI2 GND 2 21 VO1 SI 3 20 VI1 OSCI 4 19 VDD OSCO 5 18 TURBO 17 F3 RX-5B F1 6 RIGHT 7 16 FORWAR F2 8 15 F4 LEFT 9 14 BACKWAR VT 10 13 LRTD RDB 11 12 LDB PC HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 1 2002.03.26 Silan Semiconductors TX-5B/RX-5B BLOCK DIAGRAM TEST 2 OSCI 14 OSCO 13 Timing Generator Oscillator RIGHT 1 LEFT 16 TURBO 6 FORWARD 5 BACKWARD 4 11 VDD 12 PC Latch Circuit Encoding Circuit Logic 10 SO 7 SC 15 9 8 3 F1 F2 F34 GND TX-5B Block Diagram OSCI 4 Oscillator OSCO Timing Generator Counter Decoding Circuit PLA 19 VDD 5 SI 3 VO1 21 VI1 20 AMP 7 RIGHT 9 LEFT LDB 12 LRTD 13 RDB 11 VT 18 TURBO 14 BACKWARD Control Logic 16 FORWARD Latch Circuit 10 6 F1 8 F2 VI2 22 17 F3 VO2 1 15 F4 2 GND RX-5B Block Diagram HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2 2002.03.26 Silan Semiconductors TX-5B/RX-5B ABSOLUTE MAXIMUM RATINGS Characteristic Symbol Value Unit VDD 0.3 ~ 5.0 V VIN,VOUT GND-0.2V ~ VDD+0.2V V Operating Temperature Topr -10 ~ +60 °C Storage Temperature Tstg -25~+125 °C DC Supply Voltage Input/Output Voltage 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 500Hz, 1/4 duty 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 F3 F4 F2 F = Forward B = Backward T = Turbo R = Right F1 = Function1 F2 = Function2 F3 = Function3 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.
