It is a surface-mount package with gull-wing leads on 0.8 mm pitch. The Tape & Reel (TR) suffix on this ordering code means it ships on 13-inch reels for automated pick-and-place; the Cut Tape (CT) option is for prototype or low-volume builds. ## Active lifecycle — no end-of-life clock ticking For production programs, this removes the single-source risk that comes with NRND or EOL parts. The base product number is CY7C1021, and the D suffix indicates the -10 speed grade and the industrial temperature range.","metaTitle":"Infineon CY7C1021D-10ZSXIT SRAM, 1Mbit, 10 ns, 44-TSOP II","metaDescription":"Infineon CY7C1021D-10ZSXIT asynchronous SRAM, 1Mbit (64K x 16), 10 ns access time, 4.5V-5.5V, -40°C to 85°C, 44-TSOP II.
