The 4.5V to 5.5V supply rail keeps it in single-5V systems without a separate core voltage. The 28-SOJ package (0.300-inch body width) is a surface-mount footprint that mates with standard SOJ sockets or direct-solder pads. No pin-compatible direct replacement from Infineon is documented, so a board spin may be required if a functional equivalent is needed.","metaTitle":"Infineon CY7C199C-12VI 256Kbit SRAM, 12 ns, 28-SOJ","metaDescription":"CY7C199C-12VI 256Kbit asynchronous SRAM, 12 ns access, 32K x 8, 4.5-5.5V, -40 to 85°C, 28-SOJ.
