SM5021 SAMHOP Microelectronics Corp. ENCODER GENERAL DESCRIPTION The SM5021A/B is a h i g h p e r f o r m a n c e infrared remote control encoder utilizing CMOS technology. Mode A is a signal-key control and mode B is a multi-key control during data transmission, supports eight data key inputs and a LED output to indicate the status during transmission. Auto power off function when key is not pressed to save power, custom codes to distinguish different products. SM5021 encoder is paired with SM5032 decoder for more data control applications. FEATURES * Wide operation voltage range, 2.4V to 6V * Eight data key control * Option of signal-key or multi-key control * Two custom codes to separate products * Auto power off for saving power * LED output to indicate transmission status * Direct infrared LED 38KHz modulation output * Low power consumption * Paired with SM5032 decoder * 16 pin DIP or SO package APPLICATIONS * SM3015 Fan Remote Control * Audio Remote Control * Toy Remote Control * Consumer Products Remote Control PIN ASSIGNMENT (TOP VIEW) C1 C2 K1 K2 K3 K4 K5 Vss 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VDD DOUT LEDO OSC2 OSC1 K8 K7 K6 SM5021A/B Page 1 V.2.0 Mar 8,2002 SM5021 SAMHOP Microelectronics Corp.
