CYM74C430  
Intel® 82430FX PCIset Level II  
Cache Module  
Features  
Functional Description  
This secondary cache module is designed for Intel P54C sys-  
tems 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.  
Pin-compatible secondary cache module family that ad-  
heres to the Intel® COAST 1.2 specification  
Asynchronous (CYM74C430) configuration with pres-  
ence and configuration detect pins  
Ideal for Intel P54C-based systems with the 82430FX  
(Triton) chipset  
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.  
Operates at 50, 60, and 66 MHz  
Uses cost-effective CMOS asynchronous SRAMs.  
All components on the cache module are surface mounted on  
a multi-layer epoxy laminate (FR-4) substrate. All inputs and  
data outputs 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.
