LC87F7DC8A

Overview

The SANYO LC87F7DC8A 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), 4K-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, two UART ports (full duplex), an 12-bit 15-channel AD

converter, two 12-bit PWM channels, a high-speed clock counter, a system clock frequency divider, a small signal

detector, two remote control receive functions, and a 31-source 10-vector interrupt feature.
