HMP512R7FFP4C-E3
Key Features
- Negative Negative line of the differential pair of system clock inputs that drives input to the on-DIMM PLL
- Edge Active High Active Low Active High Active Low Activates the DDR2 SDRAM CK signal when high and deactivates the CK signal when low
- By deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh mode
- Enables the associated DDR2 SDRAM mand decoder when low and disables the mand decoder when high
- When the mand decoder is disabled, new mands are ignored but previous operations continue
- Rank 0 is selected by S0; Rank 1 is selected by S1 On-Die Termination signals
- When sampled at the positive rising edge of the clock
- RAS,CAS and WE(ALONG WITH S) define the mand being entered
- Reference voltage for SSTL18 inputs Power supplies for the DDR2 SDRAM output buffers to provide improved noise immunity
- For all current DDR2 unbuffered DIMM designs, VDDQ shares the same power plane as VDD pins
