Product details

45 ns access time — what it sets for bus timing

The 45 ns access time sets the bus speed floor: the host controller must allow at least 45 ns from address valid to data valid on reads, and 45 ns write cycle time for word or page writes.

Industrial temperature and 48-SSOP package

Rated for -40°C to 85°C ambient, so it fits outdoor telecom cabinets, factory-floor PLCs, and motor-drive control boards that see temperature swings. The 48-SSOP package (0.295" body width, 7.50 mm) is a fine-pitch SSOP — reworkable with hot air if the pad layout has adequate solder mask dams between pins. The Tape & Reel variant (TR suffix) is the standard for automated pick-and-place; the Cut Tape option suits prototype or low-volume builds.

Active lifecycle — no near-term end-of-life concern

Cypress lists this part as Active with ROHS3 compliance. The parallel NVSRAM family has been stable for years; no successor has been announced.

Frequently asked questions

What is the difference between CY14B256LA-SP45XIT and CY14B256LA-SP45XI?

The SP45XIT suffix indicates Tape & Reel packaging; the SP45XI suffix is typically Tube or Tray. The silicon, speed grade, temperature range, and package body are identical. Choose the XIT variant for automated assembly lines that feed from reels.

When sourcing CY14B256LA-SP45XIT, what's the closest functional second-source?

There is no pin-compatible second-source NVSRAM from another manufacturer at the same density and access time. The CY7C1399BN-12VXIT is a 256Kbit SRAM (volatile) in a similar package, but it loses data on power loss — it is not a functional replacement for the NVSRAM's non-volatile feature. For a non-volatile alternative, consider a serial EEPROM or FRAM, but those require a different interface and software changes.
