That is a common footprint in networking gear and legacy industrial controllers — the same pad layout used by many 4 Mbit and 8 Mbit async SRAMs from Cypress/Infineon and ISSI. Tape & Reel delivery (the 'T' suffix) means it feeds straight into a pick-and-place; no tube-handling step on the line. That matters for a BOM line that will run for another three to five years — you are not designing in a part that forces a respin mid-production. ## 512K x 8 vs 256K x 16 — which footprint fits The CY7C1049G30-10ZSXIT is organized 512K x 8, meaning it uses eight data lines and fills a byte-wide memory slot. The sibling CY7C1041GN30-10ZSXIT packs the same 4 Mbit density but organized 256K x 16 — sixteen data lines for a word-wide bus. If your controller has a 16-bit external bus and you need full-width reads in one cycle, the x16 part saves a mux. If you are byte-addressing a FIFO or a scratchpad, the x8 organization matches the natural width and keeps the pin count lower.","metaTitle":"Infineon CY7C1049G30-10ZSXIT 4Mbit Async SRAM, 10ns","metaDescription":"Infineon CY7C1049G30-10ZSXIT 4Mbit asynchronous SRAM with 10ns access time, organized 512K x 8.

The difference is the package suffix: the -10ZSXIT is in a 44-TSOP II, while the -10VXIT is in a different 44-pin package variant. Check the mechanical drawings — the TSOP II footprint is not pin-compatible with the VXIT package, so a board layout change is needed."},{"question":"What compliance documentation is available for CY7C1049G30-10ZSXIT?","answer":"The part is ROHS3 compliant per Infineon's listing.
