描述 Description

The LC87F6AC8A is an 8-bit microcontroller 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), 4096-byte RAM, on-chip debugging function, a vacuum fluorescent display (VFD) automatic display controller/driver, a 16-bit timer/counter (may be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timer/counter 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 used as a time-of-day clock, a high-speed clock counter, a system clock frequency divider, two synchronous SIO with automatic transfer capability, an asynchronous/synchronous SIO, two channels of 12-bit PWM modules, an 8-bit 15-channel AD converter, a small signal detector, and a 27-source 10-vector interrupt feature.

简介

LC87F6AC8A属于集成电路（IC）的微控制器。由制造生产的LC87F6AC8A微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。
