Overview
The LC87F7DC8A 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, a LCD controller/driver, sophisticated 16-bit timer/counter
(may be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs),
four 8-bit timers with a prescaler, a 16-bit timer with a prescaler (may be divided into 8-bit timers), 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, two UART ports (full duplex), an
12-bit 15-channel AD converter, two 12-bit PWM channels, a high-speed clock counter, a system clock frequency
divider, a small signal detector, two remote control receive functions, and a 31-source 10-vector interrupt feature.
