Preliminary

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)

our-Bit Single-Chip Microcontrollers

We recommend the use of reflow soldering techniques to solder-mount QFP packages.
Please consult with your Sanyo representative for details on process conditions if the package itself is to be directly
immersed in a dip-soldering bath (dip-soldering techniques).
