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.

„Interrupts

1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt
requests of the level equal to or lower than the current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest
level takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest
vector address takes precedence.
