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.
