Overview
The LC87F7J32A 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 32K-byte flash ROM (onboard
programmable), 1024-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, a UART interface (full duplex),
two 12-bit PWM channels,
a 12-bit/8-bit 10-channel AD converter, remote control receive function, a high-speed clock counter, a system clock
frequency divider, an internal reset and a 25-source 10-vector interrupt feature.
