16Kb Add-Only iButton

iButton DESCRIPTION The DS1985 16Kb Add-Only iButton is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. This information can be accessed with minimal hardware, for example a single port pin of a microcontroller.

iButton 16K位只添加

iButton® 16Kb“仅添加”(DS1985)是一款坚固耐用的读/写数据载体，可识别和存储与其所连接的产品或人员相关的信息。只需很少的硬件即可访问此信息：例如，微控制器的单个端口引脚。DS1985由工厂印刻注册编码组成，其中包括唯一的48位序列号、8位CRC和8位系列代码(0BH)加上用户可编程的16Kb EPROM。DS1985的编程和读取功能完全来自1-Wire通信线路。数据通过1-Wire协议进行串行传输，该协议只需要一根数据线和一个接地回路。如果需要，整个器件可以进行编程，然后进行写保护。或者，可以对器件进行多次编程，每次对器件进行后续编程时，都会将新数据附加到现有数据，但不会覆 • 16384位电可编程只读存储器(EPROM)通过一个信号加上地线即可进行经济实惠的通信\n\n• EPROM分为64个256位页，用于随机访问分包数据记录\n\n• 每个存储器页都可以受到永久写保护，以防止篡改\n\n• 器件是“仅添加”存储器，可以在不干扰现有数据的情况下将附加数据编程到EPROM中\n\n• 利用此架构，软件可以通过将旧页面替换为新编程的页面来修补数据\n\n• 将控制、地址、数据、电源和编程信号减少到单个数据引脚\n\n• 8位系列代码规定了DS1985与读取器的通信要求\n\n• 在2.8V至6.0V的宽电压范围内读取（-40°C至+85°C）；编程范围为11.5V;

UniqueWare iButton器件

UniqueWare™ iButton® devices (DS1982U/DS1985U) are factory-programmed versions of the iButton Add-Only devices, DS1982 (1024 bit) and the DS1985 (16Kb) respectively. They differ from the regular devices in their custom ROM family codes (see Ordering Information) and the UniqueWare Identifier 5E7h in \n• 1024 bits or 64kbits electrically programmable read only memory (EPROM) communicates with the economy of one signal plus ground \n• Unique, factory lasered and tested 64-bit registration number (8-bit family code, 36-bit serialization, 12-bit UniqueWare identifier 5E7h, 8-bit CRC tester) assures;

Ultra-High-Efficiency White LED Drivers

General Description The MAX1984/MAX1985/MAX1986 are white light-emitting diode (LED) drivers that use individual regulators to control the current of up to eight LEDs. A high-efficiency step-up regulator generates just enough voltage to keep all the current regulators in regulation. A versatile d
