LC87F2H08A中文资料8-bit Microcontroller with 8K-byte Flash ROM and 256-byte RAM数据手册ONSEMI规格书

描述 Description

The LC87F2H08A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 83.3 ns, integrates a number of hardware features such as 8K-byte flash ROM (on-board programmable), 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), an 12/8-bit 9-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, an internal reset, and a 20-source 10-vector interrupt feature.

特性 Features

• Flash ROM : 8192 × 8 bitsCapable of on-board programming with a wide range (2.2 to 5.5V) of voltage source.Block-erasable in 128 byte unitsWritable in 2-byte units
• Minimum Bus Cycle :83.3ns (12MHz at VDD=2.7V to 5.5V)100ns (10MHz at VDD=2.2V to 5.5V)250ns (4MHz at VDD=1.8V to 5.5V)Note: The bus cycle time here refers to the ROM read speed.

简介

LC87F2H08A属于集成电路（IC）的微控制器。由ONSEMI制造生产的LC87F2H08A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。
