HD404618 Series 4-Bit Single-Chip Microcomputer Rev. 6.0 Sept. 1998 Description The HD404618 Series is designed with the powerful and efficient architecture of the HMCS400 family. The MCU incorporates a high-precision dual-tone multifrequency (DTMF) circuit, LCD driver/controller, voltage comparator, and 32-kHz watch oscillator circuit. The HD404618 Series includes five chips: the HD404612 with 2-kword ROM; the HD404614 with 4kword ROM; the HD404616 with 6-kword ROM; the HD404618 with 8-kword ROM; the HD4074618 with 8-kword PROM. The HD4074618, incorporating PROM, is a ZTAT™ microcomputer that can dramatically shorten system development periods and smooth the process from debugging to mass production.
