CY7C1380D-167AXI

The CY7C1380D-167AXI is an 18-Mbit synchronous pipelined SRAM designed by Cypress Semiconductor, configured as 512K × 36 or 1M × 18 bits for high-bandwidth memory architectures. Operating at a 167 MHz clock rate with a 6 ns cycle time, it provides zero-bus-turnaround burst capability and integrates on-chip address and control registers to simplify interface timing. The device supports burst lengths of two or four words and runs from a 3.3 V supply, making it compatible with common logic levels. Housed in a thin quad flat pack (TQFP) package, it delivers dense memory capacity in a compact surface-mount footprint suitable for space-constrained PCB layouts that require deterministic, low-latency data access.

Typical applications span cache memory for high-speed DSP and FPGA arrays, packet buffering in network line cards and Gigabit Ethernet switches, and real-time data capture in defense and aerospace instrumentation. The -AXI suffix indicates an industrial temperature range (-40 °C to +85 °C), enabling reliable performance in thermally challenging environments without the cost premium of full military-grade screening. Procurement considerations for this family include evaluating long-term supply continuity, since fast asynchronous and synchronous SRAMs face periodic market constraints and selective obsolescence. Engineers and buyers should validate traceability and authorized distribution provenance when specifying this part for industrial, aerospace, or other high-reliability programs that require extended lifecycle management and consistent lot control.
