The DS1225AD-150+ is a 64K Nonvolatile SRAM product designed and manufactured by Maxim Integrated. It provides a reliable and durable memory solution that combines the access speed of static RAM with the non-volatility of read-only memory. The DS1225AD-150+ is particularly suitable for applications that require data preservation after power loss without the need for a battery.

Key Features

• Memory Size: 64K (8K x 8)
• Access Time: 150ns
• Integrated Power-Fail Circuitry: Automatically switches to backup power supply during power failures.
• Nonvolatile Write Cycle: Unlimited write cycle endurance for the SRAM.
• High Reliability: Data retention rated at over 10 years.
• Package Type: 28-Pin EDIP or 32-Pin LCC.
• Operating Temperature Range: 0°C to +70°C.

Product Description

The DS1225AD-150+ is a 64K Nonvolatile SRAM with a fast access time of 150 nanoseconds. It integrates power-fail circuitry that automatically switches to an external battery when a power failure is detected, thus preserving the integrity of the stored data. The SRAM can be written to an unlimited number of times, while the nonvolatile control circuitry ensures that the data is retained for over a decade without the need for an external battery.

This product is delivered in a JEDEC standard 28-pin EDIP or a 32-pin LCC package, providing flexibility for various hardware designs. It operates over a standard temperature range, making it suitable for industrial applications where operating conditions vary. The DS1225AD-150+ is a perfect choice for systems that cannot tolerate data loss and require fast and frequent access to the stored information, such as real-time industrial controls, robotics, and other critical systems.
