Overview
The LC87F2932A 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), 2048-byte RAM, an on-chip debugger, sophisticated 16-bit timers/counters (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 base timer serving as a time-of-day clock, day and time counter, a high-speed clock counter, a
synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous
SIO interface, a UART interface (full duplex), an 8-bit 13-channel AD converter, two 12-bit PWM channels, a
system clock frequency divider, frequency variable RC oscillation circuit, and a 26-source 10-vector interrupt feature.
