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.
