Overview

The LC662516A, LC662512A, and LC662508A 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 64-pin package.

Features and Functions

? On-chip ROM capacities of 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: 58 pins

? DTMF generator

This microcontroller incorporates a circuit that can generate two sine wave outputs, DTMF output, or a melody output for software applications.

? 8-bit serial interface: Two-wire interface (16-bit data length. Supports cascade connection.)

? 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 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 11 interrupt factors and 8 interrupt vector locations.

— External interrupts: 3 factors/3 vector locations

— Internal interrupts: 8 factors/5 vector locations (Waveform output internal interrupts: 3 factors and 1 vector; shared with external expansion interrupts)

? Flexible I/O functions

Selectable options include 20mA drive outputs, inverter circuits, 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: DIP64S, QIP64E (QFP64E)

? Evaluation ICs: LC665099 (evaluation chip) + EVA86K-ECB662500 LC66E2516(on-chip EPROM microcontroller)
