Analog Devices Inc./Maxim Integrated DS1225AD-150IND+ Environmental and export classification status description

The Maxim Integrated DS1225AD-150IND+ is a non-volatile static RAM (NVSRAM) integrated circuit that combines the functions of a static RAM and a non-volatile EEPROM. It features a 64K (8192 x 8) non-volatile SRAM with a flexible SRAM-like architecture. The memory is accessed in the same way as a standard SRAM, providing read and write access at bus speeds. The non-volatile data is automatically backed up to the EEPROM when power is removed. Functions: - Non-volatile data storage - SRAM-like read and write access - Automatic backup of data to EEPROM Applications: - Battery backup memory - Data logging - Embedded systems requiring non-volatile data storage Alternative Components: - Cypress Synchronous SRAM with Nonvolatile Backup (nvSRAM) - Renesas Electronics Ultra Low Power SRAM with EEPROM Backup Embedded Modules: - SPI and I2C interfaces for communication with the microcontroller - Backup power supply management circuitry Related Q&A: 1. What is the advantage of using a DS1225AD-150IND+ over a traditional SRAM + EEPROM combination? - The DS1225AD-150IND+ combines the functions of SRAM and EEPROM in a single chip, reducing the complexity of the system and providing faster access to non-volatile data. 2. How is the data backed up to the EEPROM in the DS1225AD-150IND+? - The data is automatically transferred to the EEPROM when the IC detects a power loss or a low-power condition, ensuring reliable non-volatile storage of critical information. 3. Can the DS1225AD-150IND+ be used in applications requiring frequent read/write operations? - Yes, the DS1225AD-150IND+ functions like a standard SRAM and supports frequent read and write operations. The data is automatically backed up to the EEPROM to ensure data retention during power loss. 4. What is the typical backup power supply voltage range supported by the DS1225AD-150IND+? - The DS1225AD-150IND+ typically supports a backup power supply voltage range from 2.7V to 5.5V, ensuring compatibility with a wide range of backup power sources. 5. Are there any specific precautions to take when handling the DS1225AD-150IND+ during installation? - When installing the DS1225AD-150IND+, avoid exposing the IC to high static electricity or excessive voltage, as it may damage the internal circuitry. Follow the recommended ESD protection guidelines during handling and installation.
