4Mbit asynchronous SRAM in a 48-ball VFBGA
The Infineon CY7C1041GN30-10BVJXI is a 4Mbit asynchronous SRAM organized as 256K x 16 bits, with a 10 ns access time and a parallel interface.
The 48-VFBGA (6x8 mm) package has a 0.75 mm ball pitch — standard enough for a 4-layer PCB fan-out, but the BGA nature means you need X-ray inspection to verify solder-joint integrity after reflow. It ships in a Tray, which is the typical handling format for BGA devices — no tape-and-reel, so plan for pick-and-place with a tray feeder or a matrix tray.
