Overview

The LC662104A, LC662106A, and LC662108A are 4-bit
CMOS microcontrollers that integrate on a single chip all
the functions required in a special-purpose telephone
controller, including ROM, RAM, I/O ports, a serial
interface, a DTMF generator, timers, and interrupt
functions. These microcontrollers are available in a 30-pin
package.

Features and Functions

• On-chip ROM capacities of 4, 6, and 8 kilobytes, and an

on-chip RAM capacity of 384 × 4 bits.

• Fully supports the LC66000 Series common instruction
set (128 instructions). (The special-purpose instructions
for TM1 and SI/01 are disabled.)

• I/O ports: 24 pins

• DTMF generator
This microcontroller incorporates a circuit that can
generate two sine wave outputs, DTMF output.

• 8-bit serial interface: one circuit

• Instruction cycle time: 0.95 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 base function using a 12-bit prescaler.

• Powerful interrupt system with 6 interrupt factors and 6
interrupt vector locations.
— External interrupts: 3 factors/3 vector locations
— Internal interrupts: 3 factors/3 vector locations

• Flexible I/O functions
Selectable options include 20-mA drive outputs, pull-up
and open drain circuits.

• Optional runaway detection function (watchdog timer)

• 8-bit I/O functions

• Power saving functions using halt and hold modes.

• Packages: DIP30SD, MFP30S

• Evaluation ICs: LC665099 (evaluation chip) + EVA86K

We recommend the use of reflow-soldering techniques to solder-mount MFP 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).
