Product details

133 MHz synchronous SRAM for buffer and cache

The CY7C1383KV33-133AXC is an 18 Mbit synchronous SRAM from Infineon (formerly Cypress) organized as 1M x 18 bits. It operates at a 133 MHz clock frequency with a 6.5 ns access time, making it suitable for high-throughput data buffering in networking, telecom, and video processing applications where deterministic read latency matters.

Supply and temperature grade

The commercial temperature grade (0°C to 70°C) restricts this exact ordering code to controlled indoor environments; if your system sees ambient above 70°C, the industrial-grade sibling (suffix 'I', CY7C1383KV33-133AXI) extends the range to 85°C.

Frequently asked questions

What is the difference between CY7C1383KV33-133AXC and CY7C1383KV33-133AXI?

Both share the same 133 MHz speed grade, 18 Mbit density, and 100-LQFP package. If your system operates in unconditioned environments, the 'AXI' version is the correct choice.

What is the access time of CY7C1383KV33-133AXC?

The access time is 6.5 ns at the rated 133 MHz clock frequency. This is the time from address assertion to valid data on the output pins, critical for meeting setup/hold margins in the memory controller.

Is CY7C1383KV33-133AXC RoHS compliant?

The part is lead-free and RoHS compliant as standard for Infineon's current production. The 'C' suffix in the ordering code denotes the commercial temperature grade, not the RoHS status — all current KV33 series devices are RoHS-compliant.
