A-Data ADABC1616
PC-133 SDRAM Unbuffered DIMM
16Mx64bits SDRAM DIMM based on 8Mx8, 4Bank, 4K Refresh, 3.3V SDRAM
General Description
The ADABC1616 is 16Mx64 bits Synchronous DRAM
Modules, The modules are composed of sixteen 8Mx8
bits CMOS Synchronous DRAMs in TSOP-II 400mil
54pin package and one 2Kbit EEPROM in 8pin
TSSOP(TSOP) package on a 168pin glass–epoxy
printed circuit board.
The A-Data is a Dual In-line Memory Module and is
intended for mounting onto 168-pins edge connector
sockets. Fully synchronous operation referenced to
the positive edge of the clock. All inputs and outputs
are synchronized with the rising edge of the clock.
The data paths are internally pipelined to achieve very
high bandwidth.
