常見問題解答

What is STK14C88-3NF45I?

The STK14C88-3NF45I is a 1 Meg (131,072 x 8) nvSRAM (non-volatile static random-access memory) with a 45 ns access time, manufactured by Cypress Semiconductor. It is designed to provide non-volatile data retention and high-speed access for applications requiring reliable data storage and fast read and write performance.

How Does STK14C88-3NF45I Work?

The STK14C88-3NF45I operates by utilizing a combination of static random-access memory (SRAM) and non-volatile electrically erasable programmable read-only memory (EEPROM) to store data. During normal operation, data is read from and written to the SRAM portion, and in the event of a power loss, the data is automatically transferred to the non-volatile EEPROM for retention.

How Many Pins does STK14C88-3NF45I have and What are the Functions of the Pinout Configuration?

The STK14C88-3NF45I is housed in a 32-pin DIP (dual in-line package) or SOIC (small outline integrated circuit) package. The pinout configuration includes:

  • VCC: Power supply pin.
  • GND: Ground pin.
  • CE: Chip enable input for read and write operations.
  • BYTE: Selects the upper or lower byte for read or write operations.
  • WE: Write enable input for write operations.
  • OE: Output enable input for read operations.
  • NC: No connect pin (not connected).
  • Address Inputs (A0-A16): Address inputs for memory addressing.
  • Data I/O (I/O0-I/O7): Data input/output pins.
  • VBAT: Backup battery input for non-volatile data retention.

What are the Pros and Cons of STK14C88-3NF45I?

Pros:

  • Non-Volatile: Retains data without the need for a continuous power supply, providing data integrity in the event of power loss.
  • High-Speed Access: Offers fast read and write access times for efficient data storage and retrieval.
  • Reliable Data Retention: Ensures long-term data retention for critical information or configuration settings.
  • Easy Integration: Can be used as a drop-in replacement for standard SRAM, simplifying system design.
  • Industrial Temperature Range: Suitable for operation in harsh environments with a wide temperature range.

Cons:

  • Complex Interface: Requires careful consideration of chip enable, write enable, and output enable control for proper operation.
  • Backup Battery Requirement: Requires an external backup battery for non-volatile data retention.
  • Package Size: The 32-pin DIP or SOIC package may take up more board space compared to smaller memory devices.

Are There Any Equivalents/Alternatives to STK14C88-3NF45I for Recommendation?

  • The FM18W08 from Cypress Semiconductor is a similar non-volatile SRAM device with a 45 ns access time.
  • Alternatives to the STK14C88-3NF45I include the DS1230Y from Maxim Integrated and the M48Z02 from STMicroelectronics.
