HD404829R Series
AS Microcomputer Incorporating a LCD controller/Driver Circuit
ADE-202-057C
Rev.4
Sept. 1999
Description
The HD404829R series incorporates an 8-bit A/D converter (four channels), a Liquid Crystal Display
(LCD) and a serial interface, and has large-current Input/Output (I/O) pins. The series is a 4-bit single-chip
microcomputer best used in the AV equipment such as CD radio cassette tape recorders which require the
LCD display control.
The HD404829R Series, with a 32.768kHz sub-oscillator for clocks, counts up the system clock and a
variety of power modes can reduce power consumption.
The HD4074829 is a ZTAT
TM
microcomputer which incorporates a PROM. System development period
has been dramatically reduced so that the process from debugging to mass production is smooth. (The
PROM programming specifications are the same as those for Type 27256.)

Caution about operation!
It has been confirmed that the HD404829R Series, same as the ZTAT
TM
version HD4074829 and the
conventional HD404829 Series, satisfies the electrical properties given on the data sheets, etc. However,
effective values of the electrical properties, the operating margin, and the noise margin may differ with the
manufacturing processes, on-chip ROM, and layout patterns. Therefore, conduct an evaluation test of your
system using the ZTAT
TM
version and the mask ROM version. Also conduct a similar evaluation test for
checkup before replacing your conventional product with the HD404829R Series.
