HD404358 Series
Rev. 6.0
Sept. 1998
Description
The HD404358 Series is a 4-bit HMCS400-Series microcomputer designed to increase program
productivity and also incorporate large-capacity memory. Each microcomputer has an A/D converter, input
capture timer, and two low-power dissipation modes.
The HD404358 Series includes seven chips: the HD404354, HD40A4354 with 4-kword ROM; the
HD404356, HD40A4356 with 6-kword ROM; the HD404358, HD40A4358 with 8-kword ROM; the
HD407A4359 with 16-kword PROM.
The HD40A4354, HD40A4356, HA40A4358, and HD407A4359 are high speed versions (minimum
instruction cycle time: 0.47
s)
The HD407A4359 is a PROM version (ZTAT
TM
microcomputer). 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. (The ZTAT
TM
version is 27256-compatible.)
