HD404849 Series 4-Bit Single-Chip Microcomputer Rev. 6.0 Sept. 1998 Description The HD404849 series of HMCS400-series microcomputers is designed to increase program productivity and also incorporate large-capacity memory. Each microcomputer has an LCD controller/driver, A/D converter, input capture circuit, 32-kHz oscillator for clock use, and four low-power dissipation modes. The HD404849 series includes the HD404848 with an 8-kword on-chip ROM, the HD4048412 with a 12kword on-chip ROM, the HD.

HD404849 Series 4-Bit Single-Chip Microcomputer Rev. 6.0 Sept. 1998 Description The HD404849 series of HMCS400-series microcomputers is designed to increase program productivity and also incorporate large-capacity memory. Each microcomputer has an LCD controller/driver, A/D converter, input capture circuit, 32-kHz oscillator for clock use, and four low-power dissipation modes. The HD404849 series includes the HD404848 with an 8-kword on-chip ROM, the HD4048412 with a 12kword on-chip ROM, the HD404849 with a 16-kword on-chip ROM, and the HD4074849 with a 16-kword on-chip PROM. On-chip ROM is available in a PROM (ZTAT™ microcomputer) version and a mask ROM version. 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. PROM programming specifications are the same as for the 27256. ZTAT ™: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.
