Overview

The LC665304A, LC665306A, LC665308A, LC665312A, and LC665316A 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, 16-value comparator inputs, timers, interrupt functions, and an optional sub-oscillator circuit. These microcontrollers are available in a 48-pin package.

Features and Functions

? On-chip ROM capacitiy of 4, 6, 8, 12, and 16 kilobytes, and an on-chip RAM capacity of 512 × 4 bits.

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

? I/O ports: 42 pins

? A sub-oscillator circuit can be used (option) This circuit allows power dissipation to be reduced by operating at lower speeds.

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

? Instruction cycle time: 0.95 to 10 μs (at 3 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 16-value comparator inputs, 20-mA drive outputs, inverter circuits, pull-up and open-drain circuits selectable as options.

? Optional runaway detection function (watchdog timer)

? 8-bit I/O functions

? Power saving functions using halt and hold modes.

? Packages: DIP48S, QIP48E (QFP48E)

? Evaluation LSIs: LC66599 (evaluation chip) + EVA800/850-TB662YXX2 LC66E5316(on-chip EPROM microcontroller)
