LC87F1A32A

Overview

The LC87F1A32A is an 8-bit microcomputer that, integrates on a single chip a number of hardware features such as

32K-byte flash ROM, 2048-byte RAM, an on-chip debugger, 16-bit timers/counters, a 16-bit timer, two 8-bit timers,

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, a full-speed USB interface (function), a 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 an

interrupt feature.
