CMOS IC
LC87F76C8A FROM 128K byte, RAM 4K byte on-chip
8-bit 1-chip Microcontroller
Overview
The LC87F76C8A is 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 128K-byte flash ROM (onboard
programmable), 4K-byte RAM, an on-chip debugger, 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 8-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 22-source 10-vector
interrupt feature.
