1. GENERAL DESCRIPTION
The W541C20X is fully compatible with W741C20X in the terms of pin assignment and IC functon. It is
a high-performance 4-bit microcontroller (
μ
C) that operates on very low current. The device contains a
4-bit ALU, two 8-bit timers, a divider, a serial port, and five 4-bit I/O ports (including 3 output ports for
LED driving). There are also seven interrupt sources and 8-level subroutine nesting for interrupt
applications. The W541C20X has two power reduction modes, hold mode and stop mode, which help
to minimize power dissipation.
The W541C20X is suitable for remote controllers, toy controllers, keyboard controllers, speech
synthesis LSI controllers, and other products.
2. FEATURES
Operating voltage: 2.4V to 5.5V
Single system clock
Oscillation frequency up to 4 MHz , Crystal or RC oscillator is selected by mask code option
High-frequency (400 KHz to 4 MHz) or low-frequency (32.768 KHz) oscillation is delected by mask
code option
Memory
2048 x 16 bit program ROM (including 2K x 4 bit look-up table)
128 x 4 bit data RAM (including 16 working registers)
21 input/output pins
Input/output ports: 4 ports/16 pins
Serial input/output port: 1 port /4 pins (high sink current for LED driving)
MFP output pin: 1 pin (MFP)
Do not be floating when it is as input or output open-drain (NMOS type).
Power-down mode
Hold function: no operation (except for oscillator)
Stop function: no operation (including oscillator)
Seven types of interrupts
Five internal interrupts (Divider 0, Timer 0, Timer 1, and Serial I/O)
Two external interrupts (Port RC and
IN
pin)
T
MFP output pin
Output is software selectable as modulating or nonmodulating frequency
Works as frequency output specified by Timer 1
Built-in 14-bit clock frequency divider circuit
