CMOS LSI
LC66354B, 66356B, 66358B
Four-bit Single-Chip Microcontrollers
On-Chip 4 K/6 K/8 K-byte ROM
Overview
The LC66354B, LC66356B and LC66358B are 42-pin
package four-bit CMOS microcontrollers that integrate on
a single chip all functions required in a control
microcontroller, including ROM, RAM, I/O ports, serial
interfaces, comparator inputs, three-value inputs, timers
and an interrupt system. These products differ from the
earlier LC66358A series in their power supply voltage
range and operating speed specifications.
Features and Functions
• ROM (with 4 K-, 6 K- and 8 K-byte capacities) and
RAM (512 4-bit digits) on chip
• LC66000 series compatible instruction set
(128 instructions)
• A total of 36 I/O port pins
• Two eight-bit serial interfaces that can be connected in
cascade to form a 16-bit interface
• Instruction cycle time: 0.92 to 10 µs (3 to 5.5 V)
The earlier LC66358A series had instruction cycle times
of from 1.96 to 10 µs (at 3 to 5.5 V) and from 3.92 to
10 µs (at 2.2 to 5.5 V).
• Powerful timer and prescaler functions
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 eight interrupts and eight
vector locations
External interrupts: three interrupts and three vector
locations
Internal interrupts: five interrupts and five vector
locations
• Flexible I/O functions
Comparator inputs, three-value inputs, 20 mA drive
outputs, 15 V withstand voltage, pull-up or open-drain
option switching
• Runaway detection function (watchdog timer) option
• Eight-bit I/O function
• Power reduction functions using halt and hold modes
• Packages: DIP42S, QIP48E (QFP48E)
• Evaluation LSI: used together
— LC66599 (evaluation chip) + EVA850/800-
TB6630X
— LC66E308 (on-chip EPROM microcontroller)

Note: 1. An RC oscillator cannot be used with the LC66354B, LC66356B and LC66358B.
2. In addition, there are differences in the output currents, comparator input voltages and other aspects.
For details, refer to the individual catalogs for the LC66308A, LC66E308 and the LC66P308.
3. These points require care when using the LC66E308 or LC66P308 for evaluation purposes.
