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....
