HT9480 -- 8-Bit Numerical Pager Controller MCU (限用产品)
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.
