Description
The MC-45D16CA721 is a 16,777,216 words by 72 bits DDR synchronous dynamic RAM module on which 9 pieces of 128M DDR SDRAM: μPD45D128842 are assembled.
These modules provide high density and large quantities of memory in a small space without utilizing the surface mounting technology on the printed circuit board.
Decoupling capacitors are mounted on power supply line for noise reduction.
Features
? 16,777,216 words by 72 bits organization (ECC type)
? Clock frequency
? Fully Synchronous Dynamic RAM with all signals except DM, DQS and DQ referenced to a positive clock edge
? Double Data Rate interface
Differential CLK (/CLK) input
Data inputs and DM are synchronized with both edges of DQS
Data outputs and DQS are synchronized with a cross point of CLK and /CLK
? Quad internal banks operation
? Possible to assert random column address in every clock cycle
? Programmable Mode register set
/CAS latency (2, 2.5)
Burst length (2, 4, 8)
Wrap sequence (Sequential / Interleave)
? Automatic precharge and controlled precharge
? CBR (Auto) refresh and self refresh
? 2.5 V ± 0.2 V Power supply for VDD
? 2.5 V ± 0.2 V Power supply for VDDQ
? SSTL_2 compatible with all signals
? 4,096 refresh cycles / 64 ms
? Burst termination by Precharge command and Burst stop command
? 184-pin dual in-line memory module (Pin pitch = 1.27 mm)
? Unbuffered type
? Serial PD
