Product details

NVSRAM that keeps data when the power drops

The CY14B101LA-SP45XIT is a 1 Mbit Non-Volatile SRAM from Infineon, organized as 128K x 8 bits with a parallel interface. It combines the fast read/write cycle of an SRAM — 45 ns access time — with built-in non-volatile storage, so data is retained at power loss without a backup battery. The 45 ns write cycle time (word/page) matches the access time, meaning the part can be written as fast as it is read, simplifying timing in memory-mapped microcontroller or FPGA designs.

Package and board-fit: 48-SSOP rework considerations

The body is low-profile, and pin 1 is clearly marked on the top, so orientation is unambiguous under magnification.

Active lifecycle and compliance

RoHS3 compliant (2015/863/EU), with no restricted substances above the threshold. The part is available in Tape & Reel (TR) or Cut Tape (CT) options, suiting both high-volume pick-and-place and prototype runs.

Frequently asked questions

What is the closest functional second-source for CY14B101LA-SP45XIT?

The CY7C109D-10ZXIT is a 1 Mbit parallel SRAM with a 10 ns access time, but it is a volatile SRAM — it loses data on power loss. The CY14B101LA is a non-volatile NVSRAM, so the two are not drop-in replacements. A board designed for the CY14B101LA expects non-volatile behavior; substituting a volatile SRAM would require a battery backup or other data-retention scheme.

What compliance documentation does Infineon provide for CY14B101LA-SP45XIT?

The part is RoHS3 compliant (2015/863/EU). Infineon provides a RoHS certificate and material declaration on request. No UL, IEC, or REACH-specific documentation is listed in the standard datasheet, but the RoHS3 compliance covers the EU restricted-substance requirements.
