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.
ZTAT™: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.
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 × 4 commons)
• Built-in oscillators
Main clock: Can be driven by ceramic oscillator, crystal oscillator, or external clock.
Subclock: 32.768-kHz crystal
• Ten interrupt sources
Four by external sources, including two in which the detection edge is programmable
