The 10 ns access time is the headline spec, but the real timing closure challenge is the board trace length from the controller to the BGA balls: at 10 ns, every inch of PCB trace eats roughly 150 ps of flight time, so keep the route short and matched. ## Industrial temperature grade and what it buys you The 125°C ceiling is the key differentiator from commercial-grade SRAMs that top out at 85°C — if your system sees 105°C in a motor-drive cabinet or an engine-bay ECU, this part holds its 10 ns access time without derating. The 256K x 16 organization is a standard x16 width, so it pairs directly with 16-bit data buses on MCUs and FPGAs without byte-lane muxing. The base product number CY7C1041 covers a family of 4Mbit asynchronous SRAMs in various speed grades (10 ns, 12 ns, 15 ns) and temperature ranges. The -10 suffix and BAJXE package code pin this variant to the 10 ns, 125°C, 48-TFBGA option — confirm the speed and temp grade match your design before committing the BOM line.","metaTitle":"Infineon CY7C1041CV33-10BAJXE SRAM, 4Mbit, 10 ns, 48-TFBGA","metaDescription":"Infineon CY7C1041CV33-10BAJXE asynchronous SRAM, 4Mbit (256K x 16), 10 ns access, 3.3V, -40 to 125°C, 48-TFBGA tray.
