The 15 ns access means the address-to-data valid delay is 15 ns max; a 5V CPLD or FPGA driving the bus must meet this setup window at the receiver, which tightens the timing closure on a 66 MHz bus. Infineon lists the CY7C199CNL-15VXI as Obsolete. ## 28-SOJ package and board integration The J-lead form factor allows visual solder-joint inspection and is rework-friendly with a hot-air station — no bottom-side thermal pad to manage. Supplied in Tube, the part is suitable for hand-place or low-volume assembly; the tube quantity is typically 13-15 units per tube depending on the supplier's packing standard.","metaTitle":"Infineon CY7C199CNL-15VXI 256Kbit SRAM, 15 ns, 28-SOJ","metaDescription":"Infineon CY7C199CNL-15VXI asynchronous SRAM, 256Kbit (32K x 8), 15 ns access, 4.5-5.5V, -40 to 85°C.
