LC662508A Datasheet | SANYO

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 mon 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 20m A 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.
