The H2A35120856B is a 512M bits DDR2 SDRAM, organized as 16,777,216 words x 4 banks x 8 bits.
This device achieves high speed transfer rates up to 800Mb/sec/pin (DDR2-800) for general applications. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks.
Inputs are latched at the cross point of differential clocks (CLK rising and /CLK falling). All I/Os are synchronized with a single ended DQS or differential DQS- /DQS pair in a source synchronous fashion.
Double Data Rate architecture: two data transfers per clock cycle
CAS Latency: 3, 4, 5 and 6
Burst Length: 4 and 8
Bi-directional, differential data strobes (DQS an/DQS ) are transmitted / received with data
Edge-aligned with Read data and center-aligned with Write data
DLL aligns DQ and DQS transitions with clock
Differential clock inputs (CLK and /CLK )
Data masks (DM) for write data
Commands entered on each positive CLK edge, data and data mask are referenced to both edges of DQS
Posted /CAS programmable additive latency supported to make command and data bus efficiency
Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)
Off-Chip-Driver impedance adjustment (OCD) and On-Die-Termination (ODT) for better signal quality
Auto-precharge operation for read and write bursts
Auto Refresh and Self Refresh modes
Precharged Power Down and Active Power Down
Write Data Mask
Write Latency = Read Latency - 1 (WL = RL - 1)
Interface: SSTL_18
Packaged in WBGA 60 Ball (8X12.5 mm2 ), using Lead free materials with RoHS compliant
