SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER

Jun.19.2007

●LCD drive control circuit

DESCRIPTION

Bias ................................................................................... 1/2, 1/3

Duty ...........................................................................1/2, 1/3, 1/4

Common output .......................................................................... 4

Segment output ........................................................................ 32

●Main clock generating circuits.............. Built-in feedback resistor

(connect to external ceramic resonator or quartz-crystal oscillator)

●Sub-clock generating circuits

The 3823 group is the 8-bit microcomputer based on the 740 fam-

ily core technology.

The 3823 group has the LCD drive control circuit, an 8-channel A/

D converter, a serial interface, a watchdog timer, a ROM correc-

tion function, and as additional functions.

The various microcomputers in the 3823 group include variations

of internal memory size and packaging. For details, refer to the

section on part numbering.

(connect to external quartz-crystal oscillator or on-chip oscillator)
