HD404639R General Description
The HD404639R Series is a member of the HMCS400-series microcomputers designed to increase program productivity with large-capacity memory. The HD404639R Series, completely compatible with the HD404639 Series, reduces current dissipation in half and includes a high-speed version. Each microcomputer has a high-precision dual-tone multi frequency (DTMF) generator, four timers, two serial interfaces, voltage comparator, input capture circuit, 32-kHz oscillator for clock, and four low-power dissipation modes.
The HD404639R Series includes 5 chips: the HD404638R and HD40A4638R with 8-kword ROM; the HD404639R and HD40A4639R with 16-kword ROM; the HD407A4639R with 16-kword PROM. HD40A4638R, HD40A4639R, HD407A4639R are high-speed versions (minimum instruction cycle time: 0.5 ms).
The HD407A4639R is a PROM version ZTATä 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 ZTATä version is 27256-compatible.)
