DESCRIPTION
The Hynix HYM76V16635AT8 Series are 16Mx64bits Synchronous DRAM Modules. The modules are composed of sixteen 8Mx8bits
CMOS Synchronous DRAMs in 400mil 54pin TSOP-II package, one 2Kbit EEPROM in 8pin TSSOP package on a 168pin glass-epoxy
printed circuit board. One 0.22uF and one 0.0022uF decoupling capacitors per each SDRAM are mounted on the PCB.
The Hynix HYM76V16635AT8 Series are Dual In-line Memory Modules suitable for easy interchange and addition of 128Mbytes
memory. The Hyundai HYM76V16635AT8 Series are fully synchronous operation referenced to the positive edge of the clock . All
inputs and outputs are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high
bandwidth.
