Overview

Ordering number : EN5997 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.
• 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.
