based on 16Mx8 SDRAM with LVTTL, 4 banks & 4K Refresh
HYM71V16655HCT8M Series
DESCRIPTION
The Hynix HYM71V16655HCT8M Series are 16Mx64bits Synchronous DRAM Modules. The modules are composed of eight
16Mx8bits 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 0.0022uF decoupling capacitors per each SDRAM are mounted on the PCB.
The Hynix HYM71V16655HCT8M Series are Dual In-line Memory Modules suitable for easy interchange and addition of 128Mbytes
memory. The Hynix HYM71V16655HCT8M 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.
