64K Nonvolatile SRAM

The DS1225Y-150+ is a nonvolatile static RAM (NV SRAM) module manufactured by Maxim Integrated (now part of Analog Devices).

Specifications:

  • Memory Size: 64K (65,536 x 8 bits)
  • Interface: Parallel
  • Supply Voltage: 5V ±10%
  • Access Time: 150 ns
  • Data Retention: Minimum 10 years without power (nonvolatile storage)
  • Operating Temperature Range: 0°C to +70°C
  • Package: 28-pin DIP (Dual In-line Package)
  • Pin Compatibility: JEDEC standard 28-pin DIP footprint

Descriptions:

  • Combines SRAM with an integrated lithium energy source and control circuitry for nonvolatile data storage.
  • Automatically switches to battery backup when power is lost, ensuring data retention.
  • No external support circuitry required for battery operation.
  • Compatible with standard SRAM interfaces for easy integration.

Features:

  • Nonvolatile Storage: Retains data for at least 10 years without power.
  • Seamless Operation: No software or hardware changes needed for battery backup.
  • High Reliability: Built-in power-fail circuitry ensures data integrity.
  • Direct SRAM Replacement: Drop-in replacement for standard SRAMs.
  • Lithium Energy Source: Integrated battery eliminates external components.

This NV SRAM is commonly used in applications requiring persistent memory, such as industrial systems, medical devices, and embedded computing.
