GENERAL DESCRIPTION
The W741L250 is a high-performance 4-bit microcontroller (
μ
C) that provides an LCD driver. The
device contains a 4-bit ALU, two 8-bit timers, a divider, a 24
×
4 LCD driver, and five 4-bit I/O ports
(including 1 output port for high sink current). There are also five interrupt sources and 8-level
subroutine nesting for interrupt applications. The W741L250 operates on very low voltage and very
low current and has two power reduction modes, hold mode and stop mode, which help to minimize
power dissipation.
The W741L250 is suitable for handheld games, watches, clocks, speech synthesis LSI controllers,
and other products.
FEATURES
Operating voltage: 1.2V to 1.8V (LCD drive voltage: 3.0V or 4.5V)
Operating frequency up to 1 MHz
Crystal/RC oscillation circuit selectable by code option for system clock
Only low-frequency clock (32.768 KHz) for crystal mode
Memory
2048
×
16 bit program ROM (including 2K
×
4 bit look-up table)
128
×
4 bit data RAM (including 16 working registers)
24
×
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)
MFP output pin: 1 pin (MFP)
Power-down mode
Hold function: no operation (except for oscillator)
Stop function: no operation (including oscillator)
Five types of interrupts
Three internal interrupts (Divider 0, Timer 0, Timer 1)
Two external interrupts (Port RC and
INT
pin)
LCD driver output
24 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 port by code option
