8-bit 1-chip Microcontroller
Overview
The LC877600B series are an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of
83.3ns, integrates on a single chip a number of hardware features such as 96K-48Kbyte ROM, 4K-byte RAM, an LCD
controller/driver, a sophisticated 16-bit timer/counter (may be divided into 8-bit timers), a 16-bit timer (may be divided
into 8-bit timers or 8-bit PWMs), four 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, a day
and time counter, a synchronous SIO interface (with automatic block transmission/reception capabilities), an
asynchronous/synchronous SIO interface, a UART interface (full duplex), a 12-bit 12-channel AD converter, two 12-bit
PWM channels, a high-speed clock counter, a system clock frequency divider, a small signal detector, an infrared remote
controller receiver function, and a 23-source 10-vector interrupt feature.
