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 12-
kword 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.
