10 ns asynchronous SRAM for 16-bit bus designs
The Infineon CY7C1021D-10ZSXIT is a 1 Mbit asynchronous SRAM organized as 64K words by 16 bits, in a 44-pin TSOP II package.
10 ns access — timing margin on a fast bus
The 10 ns access time and 10 ns write cycle time allow back-to-back reads and writes at the same rate.
64K x 16 organization — word-wide memory, no byte mux
The 64K x 16 organization presents a 16-bit data word at each address.
44-TSOP II — footprint and reflow considerations
The 44-TSOP II package (0.400 inch body width, 10.16 mm) is the thin small-outline profile variant, distinct from the wider TSOP I. 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.
