常見問題解答

What is STK16C88-WF45?

The STK16C88-WF45 is a 16K (16,384-bit) non-volatile, static RAM (NVSRAM) module manufactured by Cypress Semiconductor. It combines the benefits of both SRAM and non-volatile memory technologies, providing data retention even when power is removed. This makes it suitable for applications requiring data storage with the ability to retain information during power loss.

How Does STK16C88-WF45 Work?

The STK16C88-WF45 works by utilizing a volatile SRAM array backed up by a non-volatile ferroelectric random access memory (FRAM) or EEPROM cell. When data is written to the device, it is stored in the SRAM array and simultaneously copied to the non-volatile memory cells. During power loss, the data is maintained in the non-volatile memory, ensuring it is retained for future use.

How Many Pins does STK16C88-WF45 have and What are the Functions of the Pinout Configuration?

The STK16C88-WF45 comes in a 28-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VCC: Power supply pin.
  • GND: Ground pin.
  • NC: No connect pin.
  • CE: Chip enable pin.
  • OE: Output enable pin.
  • WE: Write enable pin.
  • DS0-DS7: Data input/output pins.
  • A0-A10: Address inputs.
  • NC: No connect pin.

What are the Pros and Cons of STK16C88-WF45?

Pros:

  • Non-Volatile Data Storage: Retains data without the need for continuous power.
  • High Endurance: Offers high read/write endurance for reliable data retention.
  • Fast Access Time: Provides quick access to stored data for efficient operation.
  • Simple Interface: Interfaces like a standard SRAM, making it easy to integrate into existing designs.
  • Wide Operating Voltage Range: Supports a wide voltage range for versatile applications.

Cons:

  • Cost: NVSRAM technology may be more expensive than traditional SRAM alternatives.
  • Complexity: Requires proper power management to ensure data integrity during power transitions.

Are There Any Equivalents/Alternatives to STK16C88-WF45 for Recommendation?

  • An equivalent to the STK16C88-WF45 is the FM1608 from Cypress Semiconductor, which offers similar NVSRAM functionality.
  • Alternatives to the STK16C88-WF45 include the DS1258 from Maxim Integrated and the MR2A16A from Renesas Electronics.
