HD404449 Series

The HD404449 Series is a HMCS400-series microcomputer designed to increase program productivity with large-capacity memory. Each microcomputer has four Timers two serial Interfaces A/D converter input capture circuit, 32-kHz Oscillator for Clock and four low-power dissipation modes. The HD404449 Series includes three chips: the HD404448 with 8-kword ROM; the HD404449 with 16- kword ROM; and HD4074449 with 16-kword PROM (ZTAT, version). The HD4074449 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.) By Renesas Technology
