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
