1 / 33 page SM8213AM NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. POCSAG Decoder For Multiframe Pagers OVERVIEW The SM8213AM is a POCSAG-standard (Post Office Code Standardization Advisory Group) signal processor LSI, which conforms to CCIR recommen- dation 584 concerning standard international wire- less calling codes. The SM8213AM supports call messages in either tone, numerical or character outputs at signal speeds of 512, 1200 or 2400 bps. The signal input stage fea- tures a built-in filter. Each of the addresses (max. 7 + 1 dummy = 8) can be assigned to any frame, which also makes the device configurable for many additional services. Each address can be independently set to ON/OFF. Furthermore, built-in buffer memory means decoded information can be fetched in sync with the micro- controller clock, thereby reducing the microcontrol- ler CPU time required. Intermittent-duty method (battery saving (BS) method) control signals, com- patible with PLL operation, and Molybdenum-gate CMOS structure makes possible the construction of low-voltage operation, low power dissipation sys- tems. The SM8213AM is available in 16-pin SSOPs.
