Preliminary W541E260
4-BIT FLASH EPROM MICROCONTROLLER
Publication Release Date: June 2003
- 1 -
Revision A2
GENERAL DESCRIPTION
The W541E260 is fully compatible with W741E260 in terms of pin assignment and IC function. It is a
high-performance 4-bit microcontroller (
μ
C) that provides an LCD driver and the flash EEPROM for
the program memory. The device contains a 4-bit ALU, two 8-bit timers, two dividers (for two
oscillators) in dual-clock operation, a 32
×
4 LCD driver, and five 4-bit I/O ports (including 1 output port
for LED driving). There are also five interrupt sources and a 8-level subroutine nesting for interrupt
applications. The W541E260 operates on very low current and has three power reduction modes, hold
mode and stop mode in single-clock operation and the dual-clock slow operation, which help to
minimize power dissipation.
This chip is available for W541C250 and W541C260 bodies, which can be selected by option code.
The W541E260 is suitable for end product manufacturer engineering testing and earlier samples
before mass production.
FEATURES
Operating voltage: 2.4V to 5.5V (LCD drive voltage: 3.0V, or 4.5V)
Crystal/Ceramic oscillator: up to 4 MHz
RC oscillator: up to 4 MHz
Dual-clock operation is selected by code option
Main oscillator
Crystal or RC oscillation circuit can be selected by code option
In crystal mode, high-frequency (400 KHz to 4 MHz) or low-frequency (32.768 KHz) oscillation
should be selected by code option
In RC mode, attention must be paid to the high/low frequency oscillation option, because the LCD
driver frequency and the ROM code emulation time are related to this option.
Sub-oscillator
Connect to 32768 Hz crystal only
Used in dual-clock operation
Memory
2048 x 16-bit program flash EEPROM (including 2K x 4-bit look-up table)
128 x 4-bit data RAM (including 16 working registers)
32 x 4 LCD data RAM
21 input/output pins
Ports for input only: 2 ports/8 pins
Input/output ports: 2 ports/8 pins
High sink current for LED driving: 1 port/4 pins
-
MFP output pin: 1 pin (MFP)
-
Do not be floating when it is as input or output open-drain (NMOS type).
