It delivers an 8.5 ns access time and operates at a 100 MHz clock frequency over a 3.135 V to 3.6 V supply. The parallel interface and 100-LQFP package make it a fit for high-speed cache buffers, network packet memory, and DSP scratchpad in telecom or test equipment where deterministic read/write latency matters. ## Active status, RoHS non-compliant The MT58L256L18F1T-8.5 carries an Active product status, meaning Micron continues to manufacture it. The RoHS compliance field is marked non-compliant, so this part contains lead (Pb) in solder balls or die-attach material. That rules it out for new EU RoHS-regulated designs but is acceptable for legacy industrial, military, or exempt applications where leaded solder is still permitted. Store the reels dry — the 100-LQFP is moisture-sensitive, and the bulk packaging may not include a moisture barrier bag.","metaTitle":"Micron MT58L256L18F1T-8.5 SYNCBURST SRAM, 4Mbit, 8.5 ns","metaDescription":"Micron MT58L256L18F1T-8.5 SYNCBURST SRAM, 4Mbit (256K x 18), 8.5 ns access, 100 MHz clock, 100-LQFP, 0°C to 70°C.
