Infineon lists this part as Obsolete. That means the manufacturer has stopped production and no further last-time-buy window is open. The only supply channel is independent distribution — surplus, new-old-stock, or broker inventory. A pin-compatible drop-in from the same NoBL™ family may exist, but without a documented cross-reference, each BOM position must be qualified against the original footprint and timing. The 0.5 mm pitch demands careful PCB layout — the supply decoupling should sit within 5 mm of each VDD/VSS pair to keep the core noise below the 3.6 V ceiling.","metaTitle":"Infineon CY7C1357C-133AXIT SRAM, 9Mbit, 133MHz, 100-TQFP","metaDescription":"CY7C1357C-133AXIT 9Mbit synchronous SRAM from Infineon, 133 MHz clock, 6.5 ns access, 100-TQFP.
