ETC HYM72V32736T8-H

32Mx72 bits
PC133 SDRAM Unbuffered DIMM
based on 32Mx8 SDRAM with LVTTL, 4 banks & 8K Refresh
HYM72V32736T8 Series
DESCRIPTION
The HYM72V32736T8 Series are 32Mx72bits ECC Synchronous DRAM Modules. The modules are composed of nine 32Mx8bits
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 HYM72V32736T8 Series are Dual In-line Memory Modules suitable for easy interchange and addition of 256Mbytes memory.
The HYM72V32736T8 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.
