133 MHz synchronous pipeline — what the clock and access time mean for your bus
The CY7C1361C-133AXIT: The 36-bit word width is the defining fit criterion — it matches processors and ASICs with a 36-bit data bus (common in networking and telecom line cards) where a narrower 32-bit part would leave two byte lanes unconnected or require a second chip. The 133 MHz clock means the part can sustain a pipelined read or write every cycle once the initial latency is absorbed, which keeps the bus saturated without wait states.
The supply range is 3.135 V to 3.6 V, which is a tight 3.3 V nominal with ±7 % tolerance.
Package and mounting — 100-TQFP layout notes
The part is supplied in a 100-LQFP package (also designated 100-TQFP, 14 mm x 20 mm body). The 0.5 mm pitch demands a PCB with fine-line etch capability — a 4-layer board with buried vias under the body is typical for fan-out.
Active lifecycle — no design-in risk
Infineon lists the CY7C1361C-133AXIT as Active. The base product number CY7C1361 covers the family; speed and temperature variants within it share the same pinout and footprint, giving a drop-in upgrade path if a faster or wider-temperature version is needed later.
The Tape & Reel (TR) packaging is the standard delivery format for automated pick-and-place assembly; reel quantities are confirmed per RFQ.
