Product details

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.

Frequently asked questions

What is the exact storage capacity and organization of MT55L256L32PF-10?

It is an 8 Mbit SRAM organized as 256K words by 32 bits (256K x 32).

What package does MT55L256L32PF-10 use and is it surface mount?

The package is a 165-ball FBGA, surface-mount. Delivery is in bulk (loose parts), not tape-and-reel.

What is the access time and maximum frequency for MT55L256L32PF-10?

Access time is 5 ns, and the maximum operating frequency is 100 MHz.

Is there a direct, drop-in replacement for MT55L256L32PF-10 if it becomes unavailable?

No direct drop-in replacement is listed in the official documentation. The closest functional sibling is the MT55L256L18P1F-10, which shares the same 5 ns access time and 100 MHz speed but is organized 256K x 18 — half the bus width, so it is not a pin-compatible swap.

Where can I buy MT55L256L32PF-10?

This part is sourced to order against an RFQ. Availability and pricing are confirmed at quote time.
