2-FUNCTION, 4-DIGIT

LCD AUTOMOTIVE CLOCK—PROGRAMMABLE

The SCL5616HW is a 2-function digital automotive clock circuit.

Fabricated on a single monolithic chip using silicon-gate CMOS PROM

technology, it offers low cost, low power, and high reliability. It also

includes digital frequency correction, stored in the internal nonvolatile

memory, for easy adjustment of the oscillator nominal frequency.

The SCL5616HW is supplied in wafer form and is rated for

continuous operation over the automotive temperature range of

-40

°C to +85°C.

FEATURES

s Digital Tuning of Crystal Frequency

s PROM for Storing Frequency Correction Information

s 12 or 24 Hour Timekeeping Option

s Flashing Colon

s Two Switches Control All Setting Functions

s High Noise Immunity

s Internal Power-Up Reset Circuitry

s Internal Voltage Regulation

Dwg. No. PC-001
