Product details

ZBT SRAM for high-throughput pipelines

The Micron MT55L128L32F1T-10 is a 4Mbit Zero Bus Turnaround (ZBT) synchronous SRAM organized as 128K x 32 bits. Its 7.5 ns access time and 100 MHz clock rate eliminate the dead cycles between read and write operations that plague standard synchronous SRAMs, making it a natural fit for network packet buffers, DSP filter coefficient storage, and any pipeline that demands back-to-back throughput without bus-turnaround penalty.

Temperature grade and deployment context

Rated for 0°C to 70°C ambient operation, this is a commercial-temperature part.

Frequently asked questions

Is MT55L128L32F1T-10 RoHS compliant?

No, the MT55L128L32F1T-10 is explicitly RoHS non-compliant. This restricts its use in EU-market designs or any project with RoHS requirements.

Can MT55L128L32F1T-10 be used with 3.3V logic?

Yes, the supply voltage range of 3.135V to 3.465V maps directly onto a 3.3V rail, so the SRAM interfaces with 3.3V logic families without level shifters.

What is the datasheet for MT55L128L32F1T-10?

The datasheet for the MT55L128L32F1T-10 is available from Micron. It covers the full timing parameters, AC/DC characteristics, and package drawing for the 100-TQFP.

What is the pinout of MT55L128L32F1T-10?

The pinout is defined in the Micron datasheet for the 100-TQFP package. The 128K x 32 organization uses a parallel address/data bus with ZBT control signals.
