The x32 data bus matches a 32-bit MCU or DSP without byte-lane multiplexing, keeping the layout clean. Access time is 9 ns at a 83 MHz clock, which leaves enough bus margin for a single-cycle read-write turnaround on most 32-bit memory controllers. The parallel interface is fixed — no serial or DDR option inside this package. Supply is 3.135 V nominal. The industrial temperature range of -40°C to 85°C covers outdoor telecom cabinets, factory-floor PLCs, and motor-drive control boards where the ambient can swing below freezing. The 100-pin TQFP package is a surface-mount footprint that reflows in a standard lead-free profile. ## Active lifecycle — no last-time-buy scramble The MT55L256L32FT-12IT carries an Active lifecycle status. That means Micron still manufactures it, and there is no announced last-time-buy window. For a BOM line that needs this density and bus width, you are not hunting surplus stock — you can qualify it into a production build with normal lead times. The part is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"Micron MT55L256L32FT-12IT ZBT SRAM, 8 Mbit, 9 ns, 100 TQFP","metaDescription":"Micron MT55L256L32FT-12IT ZBT SRAM, 8 Mbit (256K x 32), 9 ns access time, 83 MHz, industrial temp -40°C to 85°C, 100-pin TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"series":"ZBT®","frame_size":"8Mbit","Access Time":"9 ns","memory_type":"Volatile","frequency_hz":"83000000.0","package_type":"Bulk","Memory Format":"SRAM","mounting_type":"Surface Mount","interface_type":"Parallel","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"3.135","Memory Organization":"256K x 32","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.80","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/724da1e73ab1feaae855ec81f269a671.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of MT55L256L32FT-12IT?","answer":"The access time is 9 ns at 83 MHz clock frequency."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/micron/MT55L256L32FT-12IT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/micron/MT55L256L32FT-12IT when reusing this data.
