General Description

The HT9480 is a high performance pager controller. The built-in single cycle instructions (16-bit wide) and two-stage pipeline architecture of the HT9480 account for its high performance. The controller contains a full function pager decoder (POCSAG code) at 512, 1200, or 2400 bits per second data rate and an LCD display driver with a 35x4 dot output.
