The 15 ns access time means the memory can complete a read or write cycle within 15 ns of the address transition — fast enough to keep up with older 5 V CISC processors and ASICs running at 33-50 MHz without inserting wait states. The write cycle time for word and page modes matches the read access at 15 ns, so the bus timing is symmetrical. ## 28-SOJ package — surface-mount footprint for board assembly Housed in a 28-SOJ (Small Outline J-lead) package with a 0.300-inch body width, the CY7C199CN-15VXCT is a surface-mount device that reflows onto the PCB without through-hole holes. The supplier device package is 28-SOJ, matching the 28-BSOJ case code. The Tape & Reel (TR) packaging option (the -VXCT suffix) means this variant ships on 13-inch reels for high-volume assembly. Confirm the reel quantity with your assembler before committing the BOM line. Each lot is verified for authenticity and traceability before shipment.","metaTitle":"Infineon CY7C199CN-15VXCT SRAM, 256Kbit, 15ns, 28-SOJ","metaDescription":"Infineon CY7C199CN-15VXCT 256Kbit asynchronous SRAM, 15ns access, 4.5-5.5V, 28-SOJ.
