That margin shrinks with board trace delay and clock jitter, so keep the trace length under 2 inches and use a series termination resistor close to the SRAM pin. The synchronous SDR (single-data-rate) interface latches data on the rising edge only, which simplifies timing closure compared to a DDR part but halves the peak bandwidth per pin. Not rated for industrial enclosures or outdoor deployment without active cooling. Infineon lists the CY7C1387KV33-167AXC as Active. This part is still a standard production item, suitable for both new BOMs and sustaining production. The base product number CY7C1387 covers multiple speed and temperature variants, so if a future design needs the industrial-temperature sibling CY7C1387KV33-167AXI, the footprint and pinout match — only the temperature grade changes.","metaTitle":"CY7C1387KV33-167AXC Infineon 18Mbit Synchronous SRAM","metaDescription":"Infineon CY7C1387KV33-167AXC synchronous SRAM, 18Mbit (1M x 18), 167 MHz clock, 3.4 ns access, 100-TQFP, 0°C–70°C.
