The CY7C1021B-12ZXCT is a 1 Mbit asynchronous SRAM organized as 64K x 16 bits. Its 12 ns access time matches the write cycle time.
For industrial or automotive use, a wider-temperature variant would be needed.
Infineon lists the CY7C1021B-12ZXCT as obsolete.
Supplied in a 44-TSOP II package, surface-mount. The Tape & Reel (TR) shipping medium is standard for automated pick-and-place.
Yes, Infineon lists the CY7C1021B-12ZXCT as obsolete. No official replacement part number has been published, so any substitute must be validated for pin compatibility and timing.
The access time is 12 ns, matching the write cycle time. This determines the minimum bus cycle period the host processor must observe.
It comes in a 44-TSOP II surface-mount package (0.400" body width, 10.16 mm), shipped in Tape & Reel.
