Description

This secondary cache module,for example,CYM74C430 is designed for Intel P54C systems with the 82430FX (Triton) chip set. CYM74C430 is an asynchronous 256-Kbyte cache module that provides a low-cost, high-performance solution using 5V SRAMs with outputs clamped to 3.3V.

The CYM74C430 is organized as 32K by 64 data with an 8Kx8 tag that supports 3-2-2-2 reads and 4-2-2-2 writes at 66 MHz.Multiple ground pins and on-board decoupling capacitors ensure high performance with maximum noise immunity.

All components on the cache module,the CYM74C430 is surface mounted on a multi-layer epoxy laminate (FR-4) substrate. All inputs and data outputs of the CYM74C430 are (3.3V) TTL compatible. The contact pins of the module are plated with 150 micro-inches of nickel covered by 30 micro-inches of gold.
