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
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.)
