It is a volatile memory with a parallel interface, designed for high-throughput cache and buffer applications where deterministic read/write latency matters — think network switch packet buffers, base station DSP scratchpads, or test equipment waveform capture. The 10 ns access time and 66 MHz clock rate let it sustain back-to-back transactions without dead cycles, which is the whole point of a synchronous pipeline over an asynchronous SRAM. ## 10 ns access time — what it buys the bus 10 ns access time at 66 MHz allows single-cycle reads without wait states. ## Temperature grade and environment Rated for 0°C to 70°C ambient. The 100-TQFP package is surface-mount. RoHS non-compliant.","metaTitle":"MT58L256L18F1T-10 Micron SYNCBURST SRAM, 4Mbit, 10 ns","metaDescription":"Micron MT58L256L18F1T-10 SYNCBURST 4Mbit SRAM, 10 ns access time, 66 MHz clock, 256K x 18 organization, 100-TQFP.
