Features
Secondary cache modules that are ideal for the Intel
82430FX, 82430HX, and 82430VX chip sets
Complies with Intel COAST 3.0 cache module specifi-
cations
High-performance cache modules based on synchro-
nous pipelined 32Kx32 data BSRAM
All modules contain series damping resistors on the
data lines to improve system signal quality
Operates at 50, 60, and 66 MHz
160-position connector is compatible with all four Key-
ing Options defined in COAST 3.0.
3.3V compatible inputs/data outputs
Functional Description
The cache modules are designed for Intel P54C/P55C sys-
tems 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)
(512-Kbyte) are high performance modules compatible with all
three chipsets.
The
CYM74P434B
(256-Kbyte)
(512-Kbyte) are high performance modules with extended
cacheability for systems based on the 82430HX chipset.
Multiple ground pins and on-board decoupling capacitors en-
sure high performance with maximum noise immunity. All
modules have series damping resistors on the data lines.
All components 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.
