Four-Bit Single-Chip Microcontrollers

Preliminary

Overview

The LC66354C, LC66356C, and LC66358C are 4-bit
CMOS microcontrollers that integrate on a single chip all
the functions required in a system controller, including
ROM, RAM, I/O ports, a serial interface, comparator
inputs, three-value inputs, timers, and interrupt functions.
These three microcontrollers are available in a 42-pin
package.
These products differ from the earlier LC66358A Series
and LC66358B Series in the power-supply voltage range,
the operating speed, and other points.

Features and Functions

• On-chip ROM capacities of 4, 6, and 8 kilobytes, and an

on-chip RAM capacity of 512 × 4 bits.

• Fully supports the LC66000 Series common instruction
set (128 instructions).

• I/O ports: 36 pins

• 8-bit serial interface: two circuits (can be connected in
cascade to form a 16-bit interface)

• Instruction cycle time: 0.92 to 10 µs (at 2.5 to 5.5 V)
— For the earlier LC66358A Series: 1.96 to 10 µs (at

3.0 to 5.5 V) and 3.92 to 10 µs (at 2.2 to 5.5 V)

— For the earlier LC66358B Series: 0.92 to 10 µs (at

3.0 to 5.5 V)

• Powerful timer functions and prescalers
— Time limit timer, event counter, pulse width

measurement, and square wave output using a 12-bit
timer.

— Time limit timer, event counter, PWM output, and

square wave output using an 8-bit timer.

— Time base function using a 12-bit prescaler.

• Powerful interrupt system with 8 interrupt factors and 8
interrupt vector locations.
— External interrupts: 3 factors/3 vector locations
— Internal interrupts: 5 factors/5 vector locations

• Flexible I/O functions
Comparator inputs, three-value inputs, 20-mA drive
outputs, 15-V high-voltage pins, and pull-up/open-drain
options.

• Optional runaway detection function (watchdog timer)

• 8-bit I/O functions

• Power saving functions using halt and hold modes.

• Packages: DIP42S, QIP48E (QFP48E)

LC66354C, 66356C, 66358C

with 4, 6, and 8 KB of On-Chip ROM

instruction when HOLD is low.

• In hold mode, the CPU is restarted by
setting HOLD to the high level.

• This pin can be used as input port P33

along with P30 to P32.

• When the P33/HOLD pin is at the low
level, the CPU will not be reset by a low
level on the RES pin. Therefore,
applications must not set P33/HOLD low
when power is first applied.
