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. ## Write cycle and bus timing The write cycle time — word and page modes — matches the 15 ns access time.","metaTitle":"Infineon CY7C1021B-15VXET SRAM, 1Mbit, 15 ns, -40°C to 125°C","metaDescription":"Infineon CY7C1021B-15VXET 1Mbit asynchronous SRAM, 15 ns access, 4.5-5.5 V, -40°C to 125°C, 44-SOJ.
