LC662104A
LC662104A is Four-Bit Single-Chip Microcontroller manufactured by SANYO.
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 mon 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)
