CMOS IC

LC662508A, 662512A, 662516A

Four-Bit Single-Chip Microcontrollers

with 8, 12, and 16 KB of On-Chip ROM

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.

鈥?/div>

Features and Functions

鈥?On-chip ROM capacities of 8, 12, and 16 kilobytes, and

an on-chip RAM capacity of 512

脳

4 bits.

鈥?Fully supports the LC66000 Series common instruction

set (128 instructions).

鈥?I/O ports: 58 pins

鈥?DTMF generator

This microcontroller incorporates a circuit that can

generate two sine wave outputs, DTMF output, or a

melody output for software applications.

鈥?8-bit serial interface: Two-wire interface (16-bit data

length. Supports cascade connection.)

鈥?Instruction cycle time: 0.95 to 10 碌s (at 3.0 to 5.5 V)

鈥?Powerful timer functions and prescalers

鈥?/div>

鈥?Time limit timer, event counter, pulse width

measurement, and square wave output using a 12-bit

timer.

鈥?Time limit timer, event counter, PWM output, and

square wave output using an 8-bit timer.

鈥?Time base function using a 12-bit prescaler.

Powerful interrupt system with 11 interrupt factors and 8

interrupt vector locations.

鈥?External interrupts: 3 factors/3 vector locations

鈥?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)
