The Infineon CY7C09449PVA-AC is a 128Kbit synchronous dual-port SRAM organized as 4K x 32, clocked at 50 MHz over a parallel interface. It sits between two independent bus masters — typically a DSP and an FPGA, or two microcontrollers — allowing simultaneous read/write access to the same memory array without external arbitration logic. The 3V to 3.6V supply range matches common 3.3V logic families. Package is a 160-TQFP (24x24 mm), surface-mount, commercial temperature grade (0°C to 70°C).
This part belongs in indoor, temperature-controlled equipment: office networking gear, test equipment, or consumer electronics. Not rated for industrial enclosures, engine bays, or outdoor telecom cabinets where ambient can exceed 70°C.
