8 Mbit ZBT SRAM — 256K x 32, 5 ns access
The Micron MT55L256L32PF-10 is an 8 Mbit ZBT (Zero Bus Turnaround) synchronous SRAM organized as 256K words by 32 bits. The 5 ns access time and 100 MHz operating frequency make it suitable for high-throughput data buffering in networking, telecom, and test equipment where the processor bus expects back-to-back reads and writes without idle cycles.
Housed in a 165-ball FBGA, this is a surface-mount package. The bulk delivery means parts are loose in a bag or tray — not taped and reeled — so factor that into your pick-and-place setup if you are running high-volume assembly. The FBGA footprint is standard for this density; verify the ball pitch against your PCB land pattern before committing the layout.
