It clocks at 166 MHz with a 3.5 ns access time, meaning the memory controller can issue back-to-back reads and writes without dead cycles on the bus. That matters when you are sizing the memory subsystem for a network switch, a base station line card, or an industrial controller that cannot stall on a cache miss. The 36-bit word width maps cleanly to a 32-bit data bus plus a parity or ECC nibble, so you skip an external latch for the check bits. ## 166 MHz clock, 3.5 ns access — what that means for timing closure At 166 MHz the clock period is about 6 ns. With a 3.5 ns access time from clock edge to data valid, you have roughly 2.5 ns of setup margin before the next clock edge — enough to absorb PCB trace skew and package delay in a well-laid-out 100-TQFP board. The synchronous SDR interface uses a single clock edge for both address and data, so the controller does not need a DLL or PLL to align phases. Supply runs from 3.135V to 3.6V, which is the standard 3.3V rail with margin for ripple. Infineon lists this part as Active. No last-time-buy notice, no end-of-life warning on the horizon. If you need a few units for a repair or a prototype run, the same reel can be cut-taped.","metaTitle":"Infineon CY7C1354C-166AXIT SRAM, 9Mbit, 166 MHz, 3.5 ns","metaDescription":"CY7C1354C-166AXIT is a 9Mbit synchronous SRAM from Infineon with 166 MHz clock and 3.5 ns access time.

The only difference is the shipping medium: the 'T' suffix denotes Tape & Reel packaging, while the non-'T' variant comes in a tray or tube. For a pick-and-place line, you want the 'T' version; for hand assembly or small quantities, the tray version works fine."},{"question":"What is the access time of CY7C1354C-166AXIT?","answer":"The access time is 3.5 ns from the clock edge. That is the time the SRAM takes to present valid data on the outputs after the clock rises, and it sets the timing budget for the memory controller's input setup."},{"question":"Is CY7C1354C-166AXIT RoHS compliant?","answer":"The part carries the 'T' suffix, which in Infineon's (formerly Cypress) naming convention indicates a lead-free, RoHS-compliant finish.
