It delivers a 4 ns access time and operates at a 133 MHz clock frequency over a parallel interface. This part is built for high-throughput data buffers in networking equipment, telecom line cards, and test instrumentation where deterministic read-write latency matters more than density. The supply range spans 3.135 V to 3.6 V, and the device is specified for the commercial temperature range of 0°C to 70°C. ## 4 ns access time — what it means for the bus The 4 ns access time at 133 MHz allows data delivery within one clock cycle. The 256 K x 18 organization supports parity or ECC applications. ## Sourcing and availability","metaTitle":"Micron MT58L256L18P1T-7.5 SYNCBURST SRAM, 4Mbit, 4ns, 133MHz","metaDescription":"Micron MT58L256L18P1T-7.5 SYNCBURST 4Mbit SRAM, 4ns access time, 133MHz clock, 256Kx18, 100-TQFP.

It is available from the manufacturer's documentation portal."},{"question":"Can MT58L256L18P1T-7.5 replace a slower SRAM?","answer":"Yes, because it has a 4 ns access time and 133 MHz clock, it can replace a slower synchronous SRAM in the same package and voltage range, provided the controller can be configured for the faster timing. The 3.135 V to 3.6 V supply range is standard for 3.3 V logic families."},{"question":"What are alternatives to MT58L256L18P1T-7.5?","answer":"The peer parts in evidence are all NAND Flash or SPI NOR Flash devices (MT29F4G08, MT29F1G08, MT25QU256), which are non-volatile and have different interface and timing characteristics. They are not functional equivalents for a synchronous SRAM. A true alternative would be another 3.3 V, 133 MHz, 256 K x 18 synchronous SRAM in a 100-TQFP package from a different supplier."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/micron/MT58L256L18P1T-7.5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/micron/MT58L256L18P1T-7.5 when reusing this data.
