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
TM
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.

Features
35 I/O pins, including nine high-current pins (15 mA, max.), eight pins multiplexed with LCD segment
pins, and four pins multiplexed with analog input pins
Four timer/counters
Eight-bit input capture circuit
Three timer outputs (including two PWM outputs)
Two event counter inputs (including one in which the detection edge is programmable)
Clock-synchronous 8-bit serial interface
A/D converter (8 channels
8 bits)
Operation voltage 2.7 V to 6.0 V
LCD driver (32 segments
