36Mbit NoBL synchronous SRAM for high-throughput data buffering
The Infineon CY7C1460KVE33-167AXI is a 36Mbit synchronous SRAM from the NoBL™ family, organized as 1M x 36 and clocked at 167 MHz with a 3.4 ns access time. It uses a parallel memory interface and operates from a 3.135V to 3.6V supply. This is a pipelined, single-data-rate (SDR) SRAM — every clock edge presents a new address, and the registered outputs follow on the next rising edge. The NoBL architecture eliminates the dead bus cycle between read and write turns, so back-to-back transactions run at full clock rate without idle cycles. Typical deployment targets are network switch buffers, base station packet processors, and industrial controller cache where sustained throughput matters more than raw density.
167 MHz clock and 3.4 ns access — timing budget for the bus
At 167 MHz the cycle time is 6 ns. That split leaves a tight but workable margin for a 100 mm trace on a standard FR-4 board with one load per signal. If you are routing this to a FPGA or ASIC memory controller, factor the output hold time from the datasheet into your timing closure — the 167 MHz grade is the speed bin for designs that cannot tolerate a wait state on random access.
It reworks cleanly with a hot-air station at 260°C peak profile; the large body soaks heat evenly, so lifting a misaligned part without pad damage is routine.
For new designs this means no forced redesign cycle from obsolescence in the near term.
