Product details

The Micron MT55L256L18P1F-10 is a 4 Mbit ZBT (Zero Bus Turnaround) synchronous SRAM organized as 256K x 18 bits. It is designed for high-throughput applications where back-to-back read and write cycles must occur without dead cycles — think packet buffers in network switches, cache in telecom line cards, or look-up tables in FPGA-based accelerators. The 5 ns access time and 100 MHz clock rate let it keep pace with a 100 MHz bus without wait states, so timing closure on a high-speed memory interface is straightforward.

Package and mounting — 165-ball FBGA

It is surface-mount only — no socket option.

For volume BOM commitments, an RFQ is the right next step.

Frequently asked questions

Is MT55L256L18P1F-10 obsolete or end-of-life?

No, the MT55L256L18P1F-10 is listed as Active in production. There is no end-of-life notice or last-time-buy window currently in effect.

What is the access time of MT55L256L18P1F-10?

The access time is 5 ns, which allows single-cycle read/write at the rated 100 MHz clock.

Is MT55L256L18P1F-10 RoHS compliant?

No, the MT55L256L18P1F-10 is listed as RoHS non-compliant. Check your assembly house's exemption policy if lead-free solder is required.

What is the exact package and pinout of MT55L256L18P1F-10?

The package is a 165-ball TBGA (13x15 mm body), surface-mount only. The pinout is defined by the Micron ZBT SRAM family standard; consult the device datasheet for the ball-map diagram.

Does MT55L256L18P1F-10 require any special programming or configuration?

No special programming is required. It is a standard synchronous SRAM with a parallel interface; configuration is handled entirely by the memory controller at power-up.
