LC87F6AC8A集成電路（IC）的微控制器規(guī)格書PDF中文資料

LC87F6AC8A屬于集成電路（IC）的微控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的LC87F6AC8A微控制器微控制器產(chǎn)品是相對(duì)復(fù)雜的用戶可編程數(shù)字邏輯器件。這些產(chǎn)品與視為微控制器的器件密切相關(guān)，兩者之間的區(qū)別主要體現(xiàn)在制造商選擇的用詞。不過按照傳統(tǒng)，微控制器集成了工作存儲(chǔ)器，也更可能包含混合信號(hào)外設(shè)，并且往往與更簡(jiǎn)單的軟件范例結(jié)合使用，旨在重復(fù)執(zhí)行一系列預(yù)定義的任務(wù)。

Overview

The LC87F6AC8A is an 8-bit microcontroller that, centered around a CPU running at a minimum bus cycle time of 83.3

ns, 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*.

(* can be supported with the LC876A00 or LC876B00 series by selecting “User Options.”)
