18 Mbit synchronous SRAM for high-bandwidth buffer applications
The CY7C1370BV25-167AC: It uses a parallel interface and operates from a 2.375 V to 2.625 V supply, making it a fit for high-throughput data buffering in networking equipment, telecom line cards, and test instrumentation where wide-word memory is needed.
The 167 MHz clock rate and 3.4 ns access time define the performance tier for this synchronous SRAM. At 167 MHz, the memory can sustain back-to-back read or write transactions every clock cycle, delivering a peak bandwidth of roughly 6 Gbit/s on the 36-bit data bus. The 3.4 ns access time from clock edge to data valid gives the system designer a tight but manageable timing budget for setup and hold at the FPGA or ASIC interface. Designs running at this speed need controlled-impedance traces and matched-length routing on the data and address buses to avoid signal-integrity issues.
2.5 V supply — rail cleanliness matters
The CY7C1370BV25-167AC requires a 2.375 V to 2.625 V supply.
Obsolete — no direct Infineon replacement on record
Infineon lists the CY7C1370BV25-167AC as Obsolete. For new designs, a pin-compatible synchronous SRAM from another vendor or a different density/speed grade in the same family would need evaluation. For existing BOM lines, sourcing is through the independent distribution channel, where stock is quoted against an RFQ.
