This part is sourced through independent distribution against an RFQ. ## 15 ns access — timing margin for legacy buses The 15 ns access time sets the read-cycle ceiling for a 5 V parallel bus. At a 33 MHz bus clock (30 ns period), the address-to-data valid window leaves 15 ns for setup and hold — tight but workable if the controller's output delay is under 10 ns. ## 32K x 8 organization — byte-wide data path Organised as 32K words of 8 bits, the CY7C199CL-15VXCT fits a byte-wide memory map. For an 8-bit microcontroller or a legacy 16-bit CPU that banks memory in 8-bit increments, this maps directly without glue logic. ## 28-SOJ surface-mount — board-fit considerations The 28-SOJ package (300 mil body width, 7.62 mm) uses J-bend leads on a 1.27 mm pitch. The footprint is standard for 28-pin SOJ SRAMs; the solder paste stencil should match the lead width for reliable fillet formation.","metaTitle":"CY7C199CL-15VXCT Infineon SRAM, 256Kbit, 15 ns, 28-SOJ","metaDescription":"Infineon CY7C199CL-15VXCT 256Kbit asynchronous SRAM, 15 ns access, 4.5-5.5V, 28-SOJ.
