HD404612 Datasheet | Hitachi Semiconductor

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 parator, and 32-k Hz 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™ microputer that can dramatically shorten system development periods and smooth the process from debugging to mass production.
