8Mx64 bit SDRAM Unbuffered DIMM F-Series
PC/100 SDRAM Specification Supporting
based on 8Mx8 SDRAM, LVTTL, 2/4-Banks & 4K/8KRefresh
HYM7V65800A/ HYM7V65801A/ HYM7V65830A/ HYM7V65A
DESCRIPTION
The HYM7V65800A/ 65801A/ 65830A/ 65831A F-Series are high speed 3.3-Volt synchronous dynamic
RAM Modules composed of eight 8Mx8 bit Synchronous DRAMs in 54-pin TSOPII and 8-pin TSSOP 2K bit
E
2
PROM on a 168-pin glass-epoxy printed circuit board. A 0.33µF and 0.1µF decoupling capacitors per each
SDRAM are mounted on the module.
The HYM7V65800A/ 65801A/ 65830A/ 65831A F-Series are gold plated socket type Dual In-line Memory
Modules suitable for easy interchange and addition of 64M bytes memory. All addresses, data and control
inputs are latched on the rising edge of the master clock input. The data paths are internally pipelined to
achieve very high bandwidths.
