The CYM74P550A is a high performance synchronous pipelined burst 256 KB module and is based on industry standard 32Kx32 pipelined BSRAM. The CYM74P550A has series damping resistors on the data lines. The CYM74S550 and CYM74S551 are high performance synchronous burst cache modules that provide 256-Kbytes and 512-Kbytes of cache respectively. These modules support 3-1-1-1 performance at 66 MHz. All of these modules include storage for 8-bits of tag and one dirty bit. Multiple ground pins and on-board decoupling capacitors ensure high performance with maximum noise immunity.
