三合微科股份有限公司 SM5032C/D SAMHOP Microelectronics Corp. DECODER GENERAL DESCRIPTION FEATURES SM5032C/D is an infrared remote control decoder utilizing COMOS technology, paired with SM5021 for transmitter. The remote control system is capable of controlling eight functions and CP1 to CP6 can multi-decode. There is an option for two toggle signal outputs in these data control functions. * Wide operation voltage range, 2.4V to 6V Also there are two custom codes for user to separate different products. * A single terminal type oscillator by means of RC is provided * Infrared remote control receiver * Two custom code to separate products * Eight control functions for continuous signal * Mulit-key control outputs * Two toggle signal can be optioned in outputs * Low power consumption * High noise immunity APPLICATIONS * 14 pin DIP or SO package * Consumer Products Remote Control * Toy Remote Control * Audio Remote Control PIN ASSIGNMENTS Vss DI CP1 CP2 CP3 CP4 CP5 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VDD OSC C1 C2 TP1 TP2 CP6 Vss DI CP1 CP2 CP3 CP4 CP5 SM5032C 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VDD OSC C1 C2 CP8 CP7 CP6 SM5032D Page 1 V.1.0 May 28,2002 三合微科股份有限公司 SM5032C/D SAMHOP Microelectronics Corp.
