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
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
— 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.
• Packages: DIP64S, QIP64E (QFP64E)
• Evaluation ICs: LC665099 (evaluation chip) +
LC66E2516(on-chip EPROM microcontroller)
LC662508A, 662512A, 662516A
