LC877Series

Flash ROM Versions

LC87F7CC8A, LC87F7BC8A

Overview

The LC877 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 24 to 128 KB of ROM, 2048, or 4096 bytes of RAM, an LCD display controller/driver, a multifunction 16-bit timer /counter circuit that can be split into 8-bit timers, a 16-bit timer/PWM generator that can be split into 8-bit timers, four 8-bit timers with built-in prescaler, a clock time base timer, a high-speed clock counter, a system clock divider function, a synchronous SIO circuit with an automatic transfer function, a synchronous /asynchronous SIO circuit, an 8-bit A/D converter, a small-signal detection circuit, and a powerful interrupt system.

Features

■LCD display controller/driver

(48 segments 4 common signals)

■Small-signal detection circuit

(for microphone and similar signals)

■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 (LC877B series)

●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.

■Serial interface circuits

●8-bit synchronous serial interface

●8-bit synchronous/asynchronous serial interface

■AD converter

15-input 8-bit A/D converter (LC877B series)

■Remote controller receiver

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

■Watchdog timer

(using external resistor and capacitor components)

■Interrupts

20 sources/10 vectors (LC877B series)

(Multiple interrupt control with three levels: low level (L), high level (H), and highest level (X))

■High-speed multiply and divide instructions

● 16 bits	8 bits (execution time: 5 tCYC)
● 24 bits	16 bits (execution time: 12 tCYC)

●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
