Rochester Electronics DS1244WP-120IND+ Environmental and export classification status description

Overview of Maxim Integrated DS1244WP-120IND+ The DS1244WP-120IND+ is a non-volatile SRAM (static random access memory) that incorporates a battery-backed feature. It is designed to retain memory storage even in the absence of power. This component typically integrates a memory chip (SRAM) with a battery and control circuitry into a single package, making it ideal for applications that require data retention during power loss. The DS1244WP is available in a 28-pin DIP package. Functions 1. Non-volatile Storage: Retain SRAM data without external power. 2. Fast Access Times: Offers quick data reads and writes, typically accessing data in less than 120 nanoseconds. 3. Battery Backup: Contains an internal lithium battery that provides power to the SRAM during outages. 4. Direct SRAM Interface: Compatible with standard SRAM protocols, allowing for easy integration into existing systems. 5. Low Power Consumption: Draws minimal power during standby and active modes. Applications - Industrial Automation: For data logging and control systems that must retain configuration settings. - Telecommunications: Used in routers and switches for configuration and operational data storage. - Consumer Electronics: Retain user settings and preferences in devices like TVs, set-top boxes, etc. - Medical Equipment: For critical patient data storage where data integrity during power failures is essential. - Embedded Systems: General-purpose applications needing consistent data retention without complex power conservation strategies. Alternative Components 1. Microchip 23K640: A serial SRAM offering a smaller footprint and lower power usage. 2. Cypress CY14B101Q: A non-volatile SRAM with a different interface and battery backup functionality. 3. Cypress FRAM (Ferroelectric RAM): This offers non-volatility with faster write times and unlimited write cycles compared to traditional SRAM. 4. Cypress S26KL512S: A NOR flash memory option that can serve as an alternative for applications needing longer data retention with lesser power consumption. Embedded Modules - Maxim Integrated’s MAXQ microcontrollers: These may integrate non-volatile memory functionality within embedded applications. - FPGA with Embedded RAM: Certain field-programmable gate arrays include non-volatile memory options. - Raspberry Pi or Arduino Boards: With added memory modules, they can simulate temporary data retention with battery backup strategies.
