Overview

The SANYO LC872H08A/06A/04A 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 8K/6K/4K-byte ROM, 256-byte

RAM, 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), two 8-bit timers with a prescaler, a base timer serving as a time-of-day clock,

a high-speed clock counter, a synchronous SIO interface, an asynchronous/synchronous SIO interface, a UART interface

(full duplex), two 12-bit PWM channels, a 12/8-bit 9-channel AD converter, a system clock frequency divider,

an internal reset and a 20-source 10-vector interrupt feature.
