The Micron MT57W512H36JF-7.5 is a 18Mbit synchronous SRAM organized as 512K x 36, using an HSTL interface for high-speed memory buses. It is designed for networking equipment, telecom line cards, and test instrumentation where low-latency data buffering and wide-word access are required. The 500 ps access time and 133 MHz clock rate allow tight timing closure in a memory controller without wait states.
Active lifecycle — no obsolescence concern
The MT57W512H36JF-7.5 carries an Active product status per Micron's lifecycle coding. No last-time-buy or end-of-life notice is in effect. For BOM planning, this part can be specified without a near-term obsolescence risk. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Package and mounting
Supplied in a 165-ball FBGA (Fine-pitch Ball Grid Array) for surface-mount assembly. The 0°C to 70°C commercial temperature range suits indoor equipment with controlled ambient — networking racks, lab instruments, and telecom central-office gear. The 1.7 V supply rail is shared with many modern FPGAs and ASICs, simplifying the power tree.
