Product details

The Micron MT58L256L18F1T-10ITTR is a 4Mbit synchronous SRAM from the SYNCBURST™ family, organized as 256K x 18 bits. 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.

Frequently asked questions

Where can I buy MT58L256L18F1T-10ITTR and get a price?

This part is sourced through independent distribution. Submit an RFQ against your required quantity; current pricing and lead time are confirmed at quote time. No stock or price figures are published here.

What is the access time of MT58L256L18F1T-10ITTR?

The access time is 10 ns, synchronous with a 66 MHz clock. This suits 66 MHz memory controllers; for 100 MHz buses, consider the 8.5 ns variant.

What package does MT58L256L18F1T-10ITTR use?

It comes in a 100-pin TQFP (thin quad flat pack) surface-mount package, 0.5 mm pitch, suitable for standard PCB assembly.

What is the equivalent part for MT58L256L18F1T-10ITTR?

The closest functional equivalent is the MT58L256L18F1T-10, which has the same 4Mbit density, 10 ns access, and 66 MHz clock but is rated for commercial temperature (0 to 70°C) only. For industrial temperature, the -10ITTR is the correct variant.
