133 MHz synchronous SRAM — 36Mbit in a 1M x 36 configuration
The Infineon CY7C1441KV25-133BZXIT is a 36Mbit synchronous SRAM organized as 1M x 36, clocked at 133 MHz with a 6.5 ns access time. It uses a parallel interface and operates from a 2.375V to 2.625V supply.
2.5V supply rail and 133 MHz timing
The narrow 2.375V to 2.625V supply range means this SRAM requires a regulated 2.5V rail. It is not directly compatible with 3.3V or 1.8V logic families without level translation on the address and data buses. The 133 MHz clock and 6.5 ns access time suit high-throughput applications such as network buffers, telecom line cards, and industrial DSP memory where back-to-back read/write cycles are needed.
The 165-ball FBGA (15x17 mm) is a fine-pitch BGA requiring controlled impedance routing and multiple decoupling capacitors close to the supply balls. The industrial temperature rating covers most outdoor telecom and factory-floor environments without derating.
