18 Mbit HSTL SRAM — 450 ps access, 250 MHz clock
The Micron MT57W2MH8CF-4 is a 18Mbit synchronous SRAM organized as 2M x 8, with an HSTL interface and a 450 ps access time. It runs at a 250 MHz clock frequency from a 1.7 V supply, housed in a 165-ball FBGA for surface-mount assembly. This is a volatile memory part aimed at high-speed cache, networking buffers, and FPGA companion memory where every picosecond of access time matters for timing closure.
Temperature grade: commercial range
It fits indoor networking gear, test equipment, and server blades, but not outdoor or automotive environments without active cooling or a temperature-controlled enclosure.
