Overview

The LC66E2316 is an on-chip EPROM version of the LC6623XX Series CMOS 4-bit single-chip microcontrollers. The LC66E2316 provides the same functions as the LC662316A, and is pin compatible with that product. Since the LC66E2316 is provided in a window package, it can be reprogrammed repeatedly and is thus optimal for program development.

Features and Functions

• On-chip EPROM capacity of 16 kilobytes, and an onchip RAM capacity of 512 × 4 bits.

• Fully supports the LC66000 Series common instruction set (128 instructions).

• I/O ports: 36 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: one circuit

• Instruction cycle time: 0.95 to 10 µs (at 4.5 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 10 interrupt factors and 7 interrupt vector locations.

— External interrupts: 3 factors/3 vector locations

— Internal interrupts: 4 factors/4 vector locations (Waveform output internal interrupts: 3 factors and 1 vector; shared with external expansion interrupts)

• Flexible I/O functions

Selectable options include 20-mA 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: DIC42S (window), QFC48 (window)

• Evaluation LSIs: LC66599 (evaluation chip) + EVA800/850 - TB662YXX2
