FAQs

What is STK12C68-SF45I?

The STK12C68-SF45I is a 64K (8K x 8) nvSRAM (non-volatile static random access memory) integrated circuit manufactured by Cypress Semiconductor. It combines the non-volatility of a ROM with the speed and endurance of a static RAM, making it suitable for applications that require reliable, high-performance data storage with fast read and write access.

How Does STK12C68-SF45I Work?

The STK12C68-SF45I operates by storing data in non-volatile memory cells, which retain the stored information even when the power is removed. When data access is required, the device seamlessly switches between non-volatile and volatile modes, providing fast read and write operations like a traditional static RAM.

How Many Pins does STK12C68-SF45I have and What are the Functions of the Pinout Configuration?

The STK12C68-SF45I is typically available in a 32-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

VCC: Power supply pin.
GND: Ground pin.
CE1, CE2: Chip enable inputs for memory bank selection.
OE: Output enable for data output control.
WE: Write enable for data write control.
NC : No connection pin.
IO0-IO7: Data input/output pins.
NC: No connection pin.

What are the Pros and Cons of STK12C68-SF45I?

Pros:

Non-Volatile Data Storage: Retains data without the need for a backup power supply, ensuring persistent memory.
Fast Read and Write Operations: Provides high-speed access to stored data, similar to traditional static RAM.
Endurance: Offers high read and write cycle endurance for reliable long-term operation.
High Density: 64K density in a compact package, suitable for space-constrained designs.
Industrial Temperature Range: Available in industrial temperature range for harsh environment applications.

Cons:

Cost: NvSRAM devices may have a higher cost compared to standard volatile SRAM.
Complexity: Requires careful consideration of write timing and power-up sequencing for reliable operation.
Package Handling: The 32-pin SOIC package may require appropriate handling during assembly and rework processes.
