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
