HD404654 Series
4-Bit Single-Chip Microcomputer
Rev. 7.0
Sept. 1999
Description
The HD404654 Series is a member of the HMCS400-series of microcomputers designed to increase
program productivity with large-capacity memory. Each microcomputer has a high-precision dual-tone
multi-frequency (DTMF) generator, three timers, serial interface, voltage comparator, and input capture
circuit.
The HD404654 Series includes three chips: the HD404652 with 2 k-word ROM; the HD404654 with 4 k-
word ROM; and the HD4074654 with 4 k-word PROM (ZTATversion).
The HD4074654 is a PROM version (ZTATmicrocomputer). 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 ZTATversion is 27256-compatible.)
ZTAT: Zero Turn Around Time. ZTAT is a trademark of Hitachi Ltd.
