200 MHz synchronous SRAM for bandwidth-sensitive datapaths
The Infineon CY7C1382KV33-200AXC is an 18 Mbit synchronous SRAM organized 1M x 18, clocked at 200 MHz with a 3 ns access time. The x18 organization suits designs needing a parity bit per byte — common in network packet buffers, DSP coefficient storage, and telecom line-card applications where the extra bit carries control or ECC metadata without doubling the memory width.
Housed in a 100-TQFP (14x20 mm) with 0.5 mm pitch — a mainstream footprint for mid-density synchronous SRAM. The exposed pad on the bottom of the TQFP provides a thermal path to the PCB; a solid copper plane under the pad with at least nine thermal vias keeps the junction temperature within the commercial range during sustained 200 MHz operation.
The base product number CY7C1382 covers multiple speed and temperature grades — confirm the -200 speed grade and commercial temperature suffix match the BOM line before committing.
