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.

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)
