It provides a 10 ns access time with a 66 MHz clock, operating from a 3.135 V supply. The parallel interface and 100-pin TQFP footprint make it a direct fit for high-speed cache, network buffering, and DSP memory maps where deterministic read-write latency matters. Rated for the industrial temperature range of -40 to 85°C, this part is suited for outdoor telecom, factory automation, and motor-drive control boards that see thermal cycling. ## Industrial temperature rating — where it runs The -40 to 85°C range covers outdoor enclosures, unheated telecom cabinets, and factory-floor equipment near motors or ovens. The commercial-temperature sibling (MT58L256L18F1T-10) is limited to 0 to 70°C and would drift or fail in those environments. If your BOM already specifies the industrial grade, confirm the suffix matches — the -10ITTR is the tape-and-reel industrial variant. ## Package and supply voltage The 100-pin TQFP is a surface-mount package. Supply is 3.135 V nominal.","metaTitle":"MT58L256L18F1T-10ITTR SRAM, 4Mbit, 10 ns, SYNCBURST, 100TQFP","metaDescription":"MT58L256L18F1T-10ITTR 4Mbit synchronous SRAM, 256K x 18, 10 ns access, 66 MHz, industrial temp -40 to 85°C, 100TQFP.
