This part is officially listed as Obsolete. There is no direct Infineon successor order code. Sourcing runs through independent and surplus distribution.","metaTitle":"Infineon CY7C1021BN-12VXIT SRAM, 1Mbit 12ns 44-SOJ","metaDescription":"Infineon CY7C1021BN-12VXIT 1Mbit asynchronous SRAM, 12 ns access time, 5V supply, industrial temp -40°C to 85°C, 44-SOJ.
