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 HD404829R 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.)ZTATTM: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.
