W74110
4-BIT MICROCONTROLLER
Publication Release Date: April 1997

Revision A1
GENERAL DESCRIPTION
The W74110 is a single-chip CMOS 4-bit microcontroller (
μ
C) that operates on low voltage and very
low current. It contains a 4-bit ALU, a timers, a divider, a serial port, and five 4-bit input/output ports
(including one output port for driving LEDs). There are also four interrupt sources and 4-level
subroutine nesting for interrupt applications.
The W74110 has two power reduction modes
hold mode and stop mode
which help to minimize
power dissipation. The product is a powerful microcontroller for remote controllers, multiple I/O
products, keyboard controllers, speech synthesis LSI controllers, and other products.
FEATURES
Operating voltage: 1.3V - 6.0V
Operating frequency up to 1MHz for RC oscillator
Built-in crystal or RC oscillator by pin option
1024 x 16 bit program ROM
64 x 4 bit data RAM
21 input/output pins:
Ports for input only: 2 ports/8 pins
Input/output ports: 2 ports/8 pins
Ports for output only: 1 ports/4 pins (high current for LED driving)
Control output pin: 1 pin (MFP)
HOLD function: no operation (except for oscillator)
STOP function: no operation (including oscillator)
Four types of interrupts
Two internal interrupts (Divider and Timer)
Two external interrupts (Port RC &
INT
pin)
Built-in 14-bit clock frequency divider circuit
Built-in 8-bit programmable down-count timer
Powerful instruction set: 83 instruction sets
Direct and indirect addressing mode
4-level subroutine (include interrupt) nesting
All instructions are executed in one machine cycle except for indirect addressing mode
Up to 4
μ
S instruction cycle (at 1 MHz operating frequency)
Internal serial transmission port RT specified by software
