Description

The cache modules of CYM74P430B and CYM74P431B are designed for Intel P54C/P55C systems with the 82430FX, 82430HX, and 82430VX chip sets. The CYM74P430B/431B/434B/435B modules are based on industry standard 32Kx32 synchronous pipelined BSRAM.

The CYM74P430B (256-Kbyte) and CYM74P431B (512-Kbyte) are high performance modules compatible with all three chipsets.

The CYM74P434B (256-Kbyte) and CYM74P435B (512-Kbyte) are high performance modules with extended cacheability for systems based on the 82430HX chipset. Multiple ground pins and on-board decoupling capacitors ensure high performance with maximum noise immunity. CYM74P430B and CYM74P431B have series damping resistors on the data lines.

CYM74P430B and CYM74P431B on the cache modules 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 30 micro-inches of gold.
