LC87F5NC8A

Overview

The LC87F5NC8A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of

83.3ns, integrate on a single chip a number of hardware features such as 128K-byte flash ROM (onboard rewritable),

4096byte RAM, Onchip debugging function, 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, a high-speed clock counter, two synchronous SIO ports (with automatic

block transmission/reception capabilities), an asynchronous/synchronous SIO port, two UART ports (full duplex),

four 12-bit PWM channels, an 8-bit 15-channel AD converter, a system clock frequency divider, and a 29-source 10-

vector interrupt feature.
