Product details

The CY7C1371D-133AXCT is an 18Mbit synchronous SRAM from Infineon's NoBL™ series, organized 512K x 36, clocked at 133 MHz with a 6.5 ns access time. Supply voltage range is 3.135V to 3.6V – a tight 3.3V ±5% rail. If your board already runs 3.3V, this part drops in without a separate regulator; if the rail droops below 3.135V during transient, the SRAM may lose data integrity.

Infineon lists this part as Obsolete. Confirm the exact package (100-TQFP 14x20 mm) and timing before selecting an alternative.

Sourcing posture – quoted to order per RFQ

Because this part is obsolete, it is not stocked on the shelf. We source it through our network of qualified distributors and surplus channels against your BOM quantity. Submit an RFQ with your target volume and date-code window, and we will return a firm offer.

Frequently asked questions

How can I order CY7C1371D-133AXCT or check availability?

This part is obsolete, so it is not held available via RFQ confirmation. Submit an RFQ with your target quantity and date-code preference; we source it through our distributor network and return a firm price and lead-time quote. No commitment until you confirm.

What is the difference between CY7C1371D-133AXCT and CY7C1371D-133AXC?

The suffix 'T' indicates Tape & Reel packaging; the non-T variant (AXC) ships in trays or tubes. Electrically and mechanically they are identical – same 100-TQFP, same 133 MHz, same 6.5 ns access. The AXCT is the reeled version for automated assembly lines.
