Infineon (formerly Cypress) has ended production of this synchronous SRAM. For BOM lines that still require this exact density, speed grade, and package, the supply path runs through independent distribution and surplus inventory channels.
167 MHz clock, 3.4 ns access — synchronous SRAM for high-throughput buffers
That matters in networking line cards, telecom framers, and test equipment where every clock edge carries a transaction and bus-turnaround latency costs system bandwidth.
165-FBGA — reflow and handling notes
The device comes in a 165-ball FBGA package (15x17 mm body). It is a surface-mount BGA, so the reflow profile and moisture sensitivity level (MSL) need checking before the board hits the oven. If the part has been in storage past its floor-life window, bake it before reflow or it popcorns.
