The HT9580 is a high performance pager controller which can be used for Chinese Pager system applications. The HT9580 4-in-1 Character Pager Controller combines a POCSAG decoder with a M6502 microprocessor core, 2 Mbits Character ROM and 256 Kbits SRAM to provide both high decoder performance and excellent system flexibility. The decoder utilizes a 2-bit random error correction algorithm and therefore provides excellent decoder sensitivity. The controller contains a full function pager decoder at a 512, 1200, 2400 bps data rates. Using an M6502 core takes advantage of a flexible external control interface, LCD driver chips and abundant programming resources from worldwide providers. The internal SPI would communicate with SPI of FLEX^TM high speed pager decoder.
