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.
