At 133 MHz the clock period is roughly 7.5 ns, and the 6.5 ns access time leaves about 1 ns of setup margin before the next clock edge. That's tight but workable with controlled-impedance traces and proper termination on the parallel bus. If you're running a 100 MHz bus instead, the margin opens up to around 3.5 ns, which simplifies the PCB layout and lets you skip series resistors on shorter lines. ## NoBL architecture — no dead cycles on mixed transactions Standard synchronous SRAMs insert an idle cycle when switching from read to write (or vice versa). The NoBL design lets the controller issue a write on the cycle immediately after a read without a bubble. In a system doing interleaved read-modify-write operations—like a network processor updating statistics counters—that saves one clock per transaction, which at 133 MHz is 7.5 ns saved each time. The throughput gain adds up fast in high-port-count designs. ## Supply rail and temperature range — what the board sees The 3.135V to 3.6V supply covers a nominal 3.3V rail with ±5% tolerance, which is standard for most FPGA and ASIC banks. If your board runs a 3.0V core rail, this part won't work without a separate 3.3V supply. ## Package and footprint — 100-TQFP (14x20 mm) The 100-TQFP package with a 14x20 mm body and 0.5 mm pitch is a common footprint shared by many synchronous SRAMs in the 36 Mbit density class. It's a surface-mount package that reflows with standard lead-free profiles. The tray shipping medium means it arrives in antistatic trays, not tape-and-reel — something to note if your pick-and-place feeder setup expects reels. The base product number CY7C1461 covers a family of density and speed variants, so if you later need a faster or slower grade, the pinout stays the same across the 100-TQFP options.","metaTitle":"CY7C1461KV33-133AXI SRAM, 36Mbit, 133 MHz, 100-TQFP","metaDescription":"Infineon CY7C1461KV33-133AXI synchronous SRAM, 36Mbit (1M x 36), 6.5 ns access, 133 MHz.
