Product details

133 MHz synchronous SRAM with a 6.5 ns access window

It runs on a 133 MHz clock and delivers a 6.5 ns access time, which means the memory can sustain back-to-back reads at the full bus rate without wait states in most pipeline designs. The wide 36-bit word suits DSP engines, network processors, or any system that wants a single-chip data bus without byte-lane muxing.

The 3.135V to 3.6V supply rail keeps it compatible with 3.3V nominal systems while allowing margin during cold-crank or brownout conditions.

165-ball LBGA — footprint and handling

Housed in a 165-ball LBGA (15 mm x 17 mm body), the part is a surface-mount BGA. For high-volume reflow, check whether your assembly house can handle tray-fed pick-and-place or if a reel request is needed. The 1.0 mm ball pitch is standard for this density, but the BGA footprint demands careful PCB layout for signal integrity at 133 MHz.

Infineon lists the CY7C1441KV33-133BZM as Active.

Frequently asked questions

Does a pin-compatible second source exist for the CY7C1441KV33-133BZM?

No cross-reference or second-source alternate is cited in this ledger. The sourcing path is an RFQ into the allocation chain — the part is EOL/HOT with no documented successor on this record. The correct move is to ask the supplier for the official cross-reference and verify footprint and timing compatibility against the datasheet before any rework commitment.

What documentation should I request before placing a PO on this EOL/HOT part?

Full RoHS/REACH declaration, mold compound UL94 flammability rating, date-code traceability to fab lot and country of origin, and the distributor's incoming test coverage report — full AC parametric at rated Vcc versus continuity and device-ID only. Given the counterfeit risk on aged Cypress FBGA SRAM, the test coverage question is a procurement gate, not a courtesy inquiry.
