Pager Controller

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

ONE CHIP CAR ALTERNATOR REGULATOR

DESCRIPTION The devices are a ”single function” self-oscillating voltage regulator for car alternators. Integrating both the control section and the output power stage on a single chip, the devices require no external components, reducing significantly the cost of the system and increasing reli
