DS2250T中文资料柔性微控制器模块数据手册ADI规格书

描述 Description

The DS2250(T) soft microcontroller module is a fully 8051-compatible 8-bit CMOS microcontroller that offers \"softness\" in all aspects of its application. This is accomplished through the comprehensive use of nonvolatile technology to preserve all information in the absence of system VCC. The internal program/data memory space is implemented using 8, 32, or 64kB of nonvolatile CMOS SRAM. Furthermore, internal data registers and key configuration registers are also nonvolatile. An optional real-time clock gives permanently powered timekeeping. The clock keeps time to a hundredth of a second using an on-board crystal. All nonvolatile memory and resources are maintained for over 10 years at room temperature in the absence of power.

特性 Features

• 8, 32, or 64kB of NV RAM for Program and/or Data Memory Storage

• Maintains all Nonvolatile Resources for 10 Years in the Absence of VCC
• Early Warning Power-Fail Interrupt
• Software Security Feature:
• On-Chip, Full-Duplex Serial I/O Ports
• 32 Parallel I/O Lines
• Permanently Powered Real-Time Clock

简介

DS2250T属于集成电路（IC）的微控制器。由ADI制造生产的DS2250T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。
