The Infineon CY7C1021B-15VXET is a 1Mbit asynchronous SRAM organized as 64K words by 16 bits. It runs on a 4.5 V to 5.5 V supply and delivers a 15 ns access time.
The 44-SOJ package (0.400" body width, 10.16 mm) is a surface-mount footprint.
The write cycle time — word and page modes — matches the 15 ns access time.
No official pin-compatible second source or successor is listed in the lifecycle record. For a new design, check Infineon's current 5 V 1Mbit asynchronous SRAM family in 44-SOJ — pinouts are often shared across density options, but verify the access time and temperature grade against your timing budget.
It ships in a 44-SOJ surface-mount package (0.400" body width, 10.16 mm), supplied on Tape & Reel.
Rated for -40°C to 125°C, covering industrial and extended-temperature applications.
