LC87F0808A中文资料LC87F0808A: 8-bit Microcontroller with 8K-byte Flash ROM and 256-byte RAM数据手册ONSEMI规格书

描述 Description

The LC87F0808A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 50.0ns, integrates on a single chip a number of hardware features such as 8K-byte flash ROM (On-boardprogrammable), 256-byte RAM, an On-chip-debugger, 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), motor control PWM , a 10/8-bit 10-channel AD converter, a system clock frequency divider, an internal reset and a 21-source 10-vector interrupt feature. This microcomputer is suitable for small motor control equipment.

简介

LC87F0808A属于集成电路（IC）的微控制器。由制造生产的LC87F0808A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。
