HD404849 Series

4-Bit Single-Chip Microcomputer

Rev. 6.0

Sept. 1998

Description

The HD404849 series of HMCS400-series microcomputers is designed to increase program productivity

and also incorporate large-capacity memory. Each microcomputer has an LCD controller/driver, A/D

converter, input capture circuit, 32-kHz oscillator for clock use, and four low-power dissipation modes.

The HD404849 series includes the HD404848 with an 8-kword on-chip ROM, the HD4048412 with a 12-

kword on-chip ROM, the HD404849 with a 16-kword on-chip ROM, and the HD4074849 with a 16-kword

on-chip PROM.

On-chip ROM is available in a PROM (ZTAT™ microcomputer) version and a mask ROM version. A

program can be written to the PROM by a PROM writer, which can dramatically shorten system

development periods and smooth the process from debugging to mass production. PROM programming

specifications are the same as for the 27256.

ZTAT™: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.
