4-Bit Single-Chip Microcomputer

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. By Renesas Technology
