GENERAL DESCRIPTION
The W741C260 is a high-performance 4-bit microcontroller (
μ
C) with an LCD driver. The device
contains a 4-bit ALU, two 8-bit timers, two dividers, a 32
×
4 LCD driver, and five 4-bit I/O ports
(including 1 output port to drive the LEDs). There are also five interrupt sources and 8-level
subroutine nesting for interrupt applications. The W741C260 has two power reduction modes, hold
mode and stop mode, which help to minimize power dissipation.
The W741C260 has two oscillator circuits and can work in dual-clock or single-clock operation mode.
It is suitable for remote controllers, watches and clocks, speech synthesis LSI controllers, hand-held
games and other products.
FEATURES
Operating voltage: 2.2V to 5.5V (LCD drive voltage: 3.0V, or 4.5V)
Operating frequency up to 4 MHz
Crystal/RC oscillation circuit selectable by code option for system clock
32.768 KHz crystal oscillation circuit for sub-oscillator
High-frequency clock (400 KHz to 4 MHz) or low-frequency clock (32.768 KHz) for crystal mode;
selectable by code option
Memory
2048
×
16 bit program ROM (including 2K
×
4 bit look-up table)
128
×
4 bit data RAM (including 16 working registers)

×
4 LCD data RAM
21 input/output pins
Ports for input only: 2 ports/8 pins
Input/output ports: 2 ports/8 pins
Port for output only: 1 port /4 pins (high sink current to drive LEDs)
MFP output pin: 1 pin (MFP)
Power-down mode
Hold function: no operation (except for oscillator)
Stop function: no operation (including main oscillator)
Five types of interrupts
Four internal interrupts (Divider 0, Divider 1, Timer 0, Timer 1)
One external interrupt (Port RC)
LCD driver output
32 segment
×
4 common
Static, 1/2 duty (1/2 bias), 1/3 duty (1/2 or 1/3 bias), 1/4 duty (1/3 bias) driving mode can be
selected
LCD driver output pins can be used as DC output ports; selectable by code option
