MT58L128L36F1T-8.5C

Memory IC Overview

The MT58L128L36F1T-8.5C is a 4Mbit Synchronous Burst Static Random Access Memory (SRAM) manufactured by Micron Technology Inc. It features a parallel interface and is organized as 128K x 36 bits. The device supports a maximum clock frequency of 100 MHz with an access time of 8.5 ns. It is housed in a 100-TQFP package measuring 14x20.1 mm.

Memory IC Feature Summary

• Synchronous burst architecture for high-speed data transfer
• Parallel interface supporting 36-bit word width
• Standard SRAM technology for volatile memory storage

Memory IC Applications

• High-performance computing systems requiring fast random access
• Network infrastructure equipment needing low-latency buffering
• Industrial control systems utilizing synchronous memory interfaces

Memory IC Procurement Notes

Verify the specific suffix '8.5C' to confirm the 8.5 ns speed grade and commercial temperature range. Ensure the 100-TQFP package dimensions match the target PCB footprint. Confirm RoHS compliance status as historical data may vary by production batch. Cross-reference the manufacturer part number against official Micron documentation to avoid counterfeit components.

Memory IC Selection Notes

Select this component when a 36-bit data path is required for system bus compatibility. The 100 MHz synchronous operation suits applications demanding predictable timing over asynchronous alternatives. Consider the TQFP package constraints for thermal management and board space. Evaluate power consumption requirements against standard SRAM profiles for the intended operating voltage.

Memory IC Part Context

This part belongs to Micron's SYNCBURST SRAM family, designed for embedded applications requiring high bandwidth. The 4Mbit capacity provides a balance between density and speed for cache or buffer roles. The 128K x 36 organization is distinct from common 8-bit or 16-bit widths, targeting specific processor architectures.

Memory IC Replacement Considerations

Direct substitutes include other Micron parts within the same SYNCBURST series with compatible pinouts and electrical characteristics. Verify that alternative packages maintain the 100-pin configuration. Check if speed grades meet or exceed the 8.5 ns requirement for timing closure.
