LC87F1A32A

Overview

The SANYO LC87F1A32A 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 32K-byte flash ROM (onboard

programmable), 2048-byte RAM, an onchip debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit

timers), a 16-bit timer (may be divided into 8-bit timers 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, two channels of synchronous SIO interface (with automatic

block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex),

a full-speed USB interface (function), an 12-bit 12-channel AD converter (12- or 8-bit resolution selectable), two

channels of 12-bit PWM, a system clock frequency divider, an infrared remote controller receiver circuit, and a 28-

source 10-vector interrupt feature.
