Overview

The LC875 Series are 8-bit microcontrollers based on a CPU core that operates with a minimum instruction cycle time of 100 ns and feature a rich set of peripheral functions. These peripheral functions include two multifunction 16-bit timer/counter circuits that can be split into 8-bit timers, four 8-bit timers with built-in prescaler, a clock time base timer, two synchronous SIO circuits with an automatic transfer function, a synchronous/asynchronous SIO circuit, two 12-bit PWM circuits, a 12-input 8-bit A/D converter, a high-speed 8-bit parallel interface, a high-speed clock counter, a system clock divider function, and a powerful interrupt system.

Features

■Timers

●One 16-bit timer/counter with capture register (can be divided and used as two 8-bit timers)

●One 16-bit timer/counter with PWM/toggle output function (can be divided and used as two 8-bit timers)

●Four 8-bit timers with 6-bit prescaler function

●Clock time base timer

■High-speed clock counter

This circuit can count up to 20 MHz clock signals when a 10 MHz main clock frequency is used.

■SIO

●Two 8-bit SIO circuits with automatic transfer function Two 8-bit baud rate generator circuits included Maximum clock frequency: 4/3 tCYC

●One 8-bit synchronous/asynchronous SIO circuit Asynchronous operation: 8 to 2048 tCYC, synchronous operation: 2 to 512 tCYC

■AD converter: 8-bit converter with 12 input channels

■PWM: Two 12-bit variable period PWM generator circuits

■Parallel interface

Provides a polarity reversing function. Readout and write operations can be performed in 1 tCYC cycle.

■Remote controller receiver

(shared function of the P73/INT3/TOIN pin)

■Watchdog timer

(using external resistor and capacitor components)

■Interrupts (Multiple interrupt control with three levels

:low level (L), high level (H), and highest level (X))

●26 sources/10 vectors (LC875B series)

●21 sources/10 vectors (LC8752/54/5A series)

●20 sources/10 vectors (LC8757/55 series)

■High-speed multiply and divide instructions

●16 bits ⎟ 8 bits (execution time: 8 tCYC)

●24 bits ⎟ 16 bits (execution time: 12 tCYC)

■System clock divider function

●Standby functions

●Halt mode: instruction execution is stopped, peripheral circuit operation continues

●Hold mode: instruction execution is stopped, peripheral circuit operation is stopped

●Crystal hold mode: instruction execution is stopped, peripheral circuit operation other than the clock time base timer is stopped.
