Product details

Non-volatile SRAM for parallel-bus designs

The CY14B101LA-SP45XI is a 1 Mbit NVSRAM organized as 128K x 8 bits, accessed through a parallel interface with a 45 ns access time. It combines the read/write speed of an SRAM with on-chip non-volatile storage — no battery or supercap needed to retain data when power is removed. The industrial temperature grade (-40°C to 85°C) suits factory-floor controllers, outdoor telecom gear, and instrumentation that sees thermal cycling.

Housed in a 48-BSSOP package (7.50 mm body width, 0.635 mm pitch), the CY14B101LA-SP45XI mounts on standard surface-mount pads. Shipped in Tube format — not tape-and-reel. If your pick-and-place line feeds from tape, plan for a tube-to-tape transfer or order a reeled variant if one exists in the family.

ROHS3 compliant, so it meets current EU and California restrictions without exemption paperwork.

Frequently asked questions

Will CY14B101LA-SP45XI drop into a board designed for CY7C1018DV33-10VXI?

No. The CY7C1018DV33-10VXI is a volatile SRAM with the same 128K x 8 organization and parallel interface, but it loses data on power loss. The CY14B101LA-SP45XI is non-volatile and uses a different internal architecture; the pinout is not guaranteed compatible.
