HD4074654S 技术参数

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 (ZTAT version).

The HD4074654 is a PROM version (ZTAT 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 version is 27256-compatible.)
