based on 16Mx16 SDRAM with LVTTL, 4 banks & 8K Refresh
HYM72V16M636H(L)T6 Series
DESCRIPTION
The HYM72V16M636H(L)T6 Series are 16Mx64bits Synchronous DRAM Modules. The modules are composed of four 16Mx16bits
CMOS Synchronous DRAMs in 400mil 54pin TSOP-II package, one 2Kbit EEPROM in 8pin TSSOP package on a 144 pin glass-epoxy
printed circuit board. Two 0.33uF and one 0.1uF decoupling capacitors per each SDRAM are mounted on the PCB.
The HYM72V16M636H(L)T6 Series are Dual In-line Memory Modules suitable for easy interchange and addition of 128Mbytes mem-
ory. The HYM72V16M636H(L)T6 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.
