The J-lead profile means the part sits lower than a SOP and the leads are tucked under the body, which helps with board-level clearance but makes visual inspection of solder joints trickier — a side-lit inspection or X-ray is the reliable call for production verification. Cut Tape works for prototype or low-volume builds where you don't want to commit to a full reel. ## Temperature grade and environment The 44-SOJ package's thermal impedance is modest — the J-leads conduct heat into the board pads, so a solid copper pour under the body on the top layer helps keep junction temperature within limits during sustained burst reads. ## Active lifecycle — current production from Infineon Listed as Active with no NRND or EOL flags — Infineon continues to manufacture this part, so it remains a valid BOM line for both new designs and production sustainment.","metaTitle":"CY7C1021DV33-10VXIT 1Mbit Async SRAM, 10 ns, 44-SOJ","metaDescription":"Infineon CY7C1021DV33-10VXIT 1Mbit asynchronous SRAM, 10 ns access time, 64K x 16, 3V-3.6V, -40°C to +85°C, 44-SOJ.
