HD404818 Series

4-Bit Single-Chip Microcomputer

Preliminary

Rev. 2.0

Sept. 1998

Description

The H D404818 Series of 4-bit single-chip HMCS400 series microcomputers provide high program

productivity. It incorporates a large size memory, LCD controller/driver, voltage comparator, and 32-kHz

watch oscillator circuit.

The HD404818 Series has both standard voltage versions and low voltage versions available. The standard

voltage versions operate at 4.0 V to 6.0 V (mask ROM version) and 4.0 V to 5.5 V (PROM version), while

the low voltage versions operate at 2.7 V to 6.0 V (mask ROM) and 3.0 V to 5.5 V (PROM). Low voltage

versions include an L in their product name.

Standard voltage versions: HD404812, HD404814, HD404816, HD404818, HD4074818

Low voltage versions: HD40L4812, HD40L4814, HD40L4816, HD40L4818, HD407L4818

The HD4074818 and HD407L4818, containing PROMs, are ZTAT microcomputers which can

dramatically shorten system development time and smoothly proceed from debugging to mass production.
