With a 5 ns access time and 100 MHz clock rate, it is designed for high-throughput cache, FIFO, and buffer applications in networking, telecom, and computing equipment that demand single-cycle back-to-back reads and writes without bus-turnaround dead cycles. The 32-bit-wide organization maps directly to a 32-bit datapath, saving the byte-lane muxing and extra PCB routing that narrower parts require. ## 128K x 32 organization — BOM fit for 32-bit systems The 128K x 32 organization means one chip provides 4Mbit of storage on a full 32-bit data bus. ## Temperature grade: 0°C to 70°C — indoor use only The commercial temperature range (0°C to 70°C) limits this part to indoor, temperature-controlled environments such as server rooms, telecom central offices, and benchtop test equipment. It is not rated for industrial or automotive applications where ambient temperature can exceed 70°C or drop below 0°C. ## Package and mounting Housed in a 100-pin TQFP (thin quad flat pack) for surface-mount assembly. The fine-pitch leads require careful solder-paste stencil design and reflow profile control, typical for TQFP packages. No special handling beyond standard MSL precautions. The SYNCBURST family uses a synchronous pipeline architecture that eliminates the dead cycles associated with asynchronous SRAM when switching between read and write. This makes it a natural fit for high-speed cache and FIFO applications where back-to-back transactions are the norm.","metaTitle":"Micron MT58L128L32P1T-10 SRAM, 4Mbit, 5 ns, 100 MHz SYNCBURST","metaDescription":"Micron MT58L128L32P1T-10 SYNCBURST 4Mbit SRAM, 128K x 32, 5 ns access, 100 MHz, parallel interface, 3.3 V, 100 TQFP.
