3 / 149 page  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.) ZTAT TM: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd. Features • 1,876-digit × 4-bit RAM • 44 I/O pins, including 10 high-current pins (15 mA, max.) and 20 pins multiplexed with LCD segment pins • Four timer/counters • 8-bit input capture circuit • Three timer outputs (including two PWM out-puts) • Two event counter inputs (including one double-edge function) • Clock-synchronous 8-bit serial interface • A/D converter (4 channels × 8 bits) • LCD controller/driver (52 segments × 4 commons) • Built-in oscillators Main clock: 4.2-MHz ceramic (an external clock is also possible) Subclock: 32.768-kHz crystal • Eleven interrupt sources Five by external sources, including three double-edge functions |
