FAQs

What is DS1225Y-200+?

The DS1225Y-200+ is a non-volatile static RAM (NVSRAM) integrated circuit designed by Maxim Integrated. It combines the functions of a static RAM and a non-volatile storage array, allowing it to retain data even when power is disconnected. This makes it suitable for applications requiring persistent memory, such as industrial automation, embedded systems, and battery-backed data logging.

How Does DS1225Y-200+ Work?

The DS1225Y-200+ operates by utilizing a CMOS static RAM with a self-contained lithium energy source and control circuitry. When power is applied, data can be read from and written to the device like a standard RAM. When power is removed, the lithium energy source powers the non-volatile circuitry, preserving the data. Upon re-application of power, the data is restored for read and write operations.

How Many Pins does DS1225Y-200+ have and What are the Functions of the Pinout Configuration?

The DS1225Y-200+ is housed in a 28-pin DIP (Dual Inline Package) package. The pinout configuration includes:

VCC: Power supply pin.
GND: Ground pin.
CE, WE, OE: Chip enable, write enable, and output enable control pins.
NC: No connect pin.
A0-A13: Address input pins.
DQ0-DQ7: Data input/output pins.

What are the Pros and Cons of DS1225Y-200+?

Pros:

Non-Volatile Storage: Retains data without power, providing persistent memory.
High Reliability: The integrated lithium energy source and control circuitry ensure reliable non-volatile operation.
Fast Access Time: Operates as a fast static RAM for high-speed data access.
Ease of Integration: Can be used as a drop-in replacement for equivalent static RAMs.
Wide Voltage Range: Supports a wide operating voltage range for flexibility in various systems.

Cons:

Cost: NVSRAMs typically have a higher cost compared to standard static RAMs.
Complexity: Requires consideration of the non-volatile aspects during system design and testing.
Package Size: The 28-pin DIP package may require more board space compared to surface-mount alternatives.

Are There Any Equivalents/Alternatives to DS1225Y-200+ for Recommendation?

The DS1245Y-70+ from Maxim Integrated is a similar non-volatile static RAM with a different capacity and access time.
Alternatives to the DS1225Y-200+ include the FM18W08 from Cypress Semiconductor and the M48Z02 from STMicroelectronics.
