What this synchronous SRAM is and where it fits
The CY7C1363A-100AC is a 9 Mbit synchronous SDR SRAM organized as 512K words by 18 bits. It runs on a 100 MHz clock with an 8 ns access time.
100 MHz clock and 8 ns access — what they mean for the bus
The 100 MHz clock defines the data transfer rate on the parallel bus. The 8 ns access time is measured from the rising clock edge to data valid.
Commercial temperature grade — deployment boundary
Rated 0°C to 70°C, this part is intended for indoor, temperature-controlled environments — office networking gear, telecom central-office equipment, test instrumentation, and similar rack-mount or benchtop systems. It is not specified for industrial enclosures, outdoor cabinets, or automotive under-hood locations where ambient temperatures exceed 70°C or drop below freezing.
