RX-2B

Silan Semiconductors TX-2B/RX-2B REMOTE CONTROLLER WITH FIVE FUNCTIONS DESCRIPTION The TX-2B/RX-2B is a pair of CMOS LSIs designed for remote controlled car applications. The TX-2B/RX-2B has five control keys for controlling the motions (i.e. forward, backward, rightward, leftward and the turbo function ) of the remote controlled car. FEATURES * Wide operating voltage range (VCC=1.5~5.0V) * Low stand-by current * Auto-power-off function for TX-2B * Few external components are needed TX-2B DIP-14 RX-2B DIP-16 ORDERING INFORMATION Part No. Package TX-2B DIP-14-300-2.54 RX-2B DIP-16-300-2.54 BLOCK DIAGRAM OSCI 12 OSCO 11 FOSC 13 Oscillator TEST B 2 Timing Generator RIGHT 1 9 VDD LEFT 14 TURBO 6 FORWARD 5 Latch Circuit Encoding Circuit Logic 10 PC 8 SO 7 SC BACKWARD 4 3 GND TRANSMITTER TX-2B Block Diagram HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 1.0 2002.03.29 1 Silan Semiconductors TX-2B/RX-2B BLOCK DIAGRAM OSCI 4 OSCO 5 SI 3 VO1 15 VI1 14 LDB 9 RDB 8 VI2 16 VO2 1 Oscillator AMP Timing Generator Decoding Circuit Control Logic Computer PLA Latch Circuit 2 GND RECEIVER RX-2B Block Diagram 13 VDD 6 RIGHT 7 LEFT 12 TURBO 10 BACKWARD 11 FORWARD PIN CONFIGURATION RIGHT 1 TEST 2 GND 3 ACKWARD 4 FORWARD 5 TURBO 6 SC 7 14 LEFT 13 FOSC 12 OSCI 11 OSCO 10 PC 9 VDD 8 SO TX-2B RX-2B VO2 1 GND 2 SI 3 OSCI 4 OSCO 5 RIGHT 6 LEFT 7 ROB 8 16 VI2 15 VO1 14 VI1 13 VDD 12 TURBO 11 FORWARD 10 BACKWARD 9 LDB HANGZHOU SILAN MICROELECTRONICS JOIN...
