Product details

Synchronous SRAM for high-throughput datapaths

The Infineon CY7C1350G-133AXIT is a 4.5 Mbit synchronous SRAM from the NoBL (No Bus Latency) family, organized 128K x 36. It clocks at 133 MHz with a 4 ns access time, meaning the memory controller can start a new read or write on every clock edge without dead cycles between back-to-back transactions. The 36-bit word width suits it for processor local memory, networking packet buffers, or DSP coefficient storage where a wide datapath saves chip count.

No extended or military grade here, but the industrial rating handles most controlled environments and many harsh ones.

Housed in a 100-TQFP (14x20 mm) — a common, inspectable, and reworkable package. The 0.5 mm pitch fine-line QFP needs a decent soldering profile but is hand-solderable with practice.

Lifecycle — active, no obsolescence flag

Infineon lists the CY7C1350G-133AXIT as Active. No last-time-buy notice, no NRND designation.

Frequently asked questions

What are the specifications of CY7C1350G-133AXIT?

It is a 4.5 Mbit synchronous SRAM organized 128K x 36, with a 133 MHz clock, 4 ns access time, 3.135–3.6 V supply, in a 100-TQFP (14x20 mm) package, rated -40 to 85°C.

Does CY7C1350G-133AXIT come in tape and reel?

Yes, the 'T' suffix in the order code indicates Tape & Reel packaging. The part is supplied on a reel suitable for automated pick-and-place assembly.

What is the access time of CY7C1350G-133AXIT?

The access time is 4 ns, which at a 133 MHz clock gives a single-cycle read latency from address to data valid — critical for zero-wait-state processor memory.

Is CY7C1350G-133AXIT lead-free?

The 'T' suffix in the part number typically indicates lead-free (RoHS-compliant) finish, but the evidence does not list a specific RoHS status. Confirm with the datasheet or your Infineon rep for the exact plating.
