What this 36 Mbit synchronous SRAM does in a cache line
The CY7C1440AV33-250AXCT: This part is designed for high-speed cache, buffer, and lookup-table applications in networking, telecom, and computing equipment where single-data-rate (SDR) synchronous SRAM is the standard.
250 MHz clock and 2.6 ns access — timing budget for the bus
The 250 MHz clock frequency and 2.6 ns access time are the critical timing parameters for this part.
If the design sees -40°C or +85°C, look at the industrial-temperature sibling CY7C1441KV33-133AXI.
Package and footprint — 100-TQFP, Tape & Reel
The Tape & Reel (TR) packaging is feeder-ready for high-volume pick-and-place.
