LC87F7LC8A
CMOS IC
FROM 128K byte, RAM 4096 byte on-chip
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F7LC8A 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 128K-byte flash ROM (onboard
programmable), 4096-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), an 8-bit 15-channel
AD converter, two 12-bit PWM channels, a high-speed clock counter, a system clock frequency divider, a small signal
detector, ROM correction function, remote control receive function, and a 28-source 10-vector interrupt feature.
