Preliminary W541E260

4-BIT FLASH EPROM MICROCONTROLLER

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 (µC) 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).
