LC877917A

Overview

The SANYO LC877917A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time

of 250ns, integrates on a single chip a number of hardware features such as 16K-byte ROM, 512-byte RAM, 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 calendar function (RTC), a

synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO

interface, a UART interface (full duplex), a 12-bit/8-bit 7-channel AD converter, high-speed clock counter, a system

clock frequency divider, a power on reset function and a 21-source 10-vector interrupt feature.
