LC662108A Datasheet | 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) - Powerful timer functions and prescalers - Time limit timer, event counter, pulse width measurement, and square wave output using a 12-bit timer. - Time base function using a 12-bit prescaler. - Powerful interrupt system with 6 interrupt factors and 6 interrupt vector locations. - External interrupts: 3 factors/3 vector locations - Internal interrupts: 3 factors/3 vector locations - Flexible I/O functions Selectable options include 20-m A drive outputs, 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: DIP30SD, MFP30S - Evaluation ICs: LC665099 (evaluation chip) + EVA86K - ECB662500 LC66E2108(on-chip EPROM microcontroller) Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
