LC87F5NC8A
CMOS IC
FROM 128K byte, RAM 4096 byte on-chip
8-bit 1-chip Microcontroller
Overview
The SANYO 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.
