Description

This family of secondary cache modules,such as CYM74P430 is designed for Intel P54C systems with the 82430FX (Triton) chipset. CYM74B430 is an asynchronous 256-Kbyte cache module that provides a low-cost, high-performance solution with industry standard 32Kx8 5V SRAMs and 3.3V level translators. The CYM74B430 is organized as 32K by 64-bits with an 8Kx8 tag that supports 3-2-2-2 read and 4-2-2-2 write cycles at CPU bus speeds up to 66 MHz.

The synchronous modules are available with low cost synchronous pipelined RAMs, or high performance synchronous burst RAMs. The synchronous pipelined modules are based on a 16Kx64 RAM. The CYM74P430 is a 256-KB module while the CYM74P431 is a 512-KB module.

The CYM74S430 and CYM74S431 are high performance synchronous burst cache modules that provide 256 KB and 512 KB of cache respectively. The CYM74P430,CYM74S430 and CYM74S431 support 3-1-1-1 performance at 66 MHz. Multiple ground pins and on-board decoupling capacitors ensure high performance with maximum noise immunity.

All components on the cache modules,the CYM74P430 are surface mounted on a multi-layer epoxy laminate (FR-4) substrate. The contact pins are plated with 150 micro-inches of nickel covered by 10 micro-inches of gold flash.
