HDD32M72B18RPW
DDR SDRAM Module 256Mbyte (32Mx72bit), based on 16Mx8, 4Banks, 4K
Ref., 184Pin-DIMM with PLL & Register
Part No. HDD32M72D18RPW
GENERAL DESCRIPTION
The HDD32M72D18RPW is a 64M x 72 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory
module. The module consists of eighteen CMOS 16M x 8 bit with 4banks DDR SDRAMs in 66pin TSOP-II 400mil packages
and 2K EEPROM in 8-pin TSSOP package on a 184-pin glass-epoxy. Four 0.1uF decoupling capacitors are mounted on
the printed circuit board in parallel for each DDR SDRAM. The HDD32M72D18RPW is a DIMM(Dual in line Memory
Module) .Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible
on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allows the same device
to be useful for a variety of high bandwidth, high performance memory system applications. All module components may be
powered from a single 2.5V DC power supply and all inputs and outputs are SSTL_2 compatible.

PIN FUNCTION DESCRIPTION
Pin
CK, /CK
Name
Input Function
CK and CK are differential clock inputs. All address and control input signals are
sam-pled on the positive edge of CK and negative edge of CK. Output (read) data
Clock
is referenced to both edges of CK. Internal clock signals are derived from CK/CK.
CKE HIGH activates, and CKE LOW deactivates internal clock signals, and device
input buffers and output drivers. Deactivating the clock provides PRECHARGE
POWER-DOWN and SELF REFRESH operation (all banks idle), or ACTIVE
POWER-DOWN(row ACTIVE in any bank). CKE is synchronous for all functions
CKE
Clock Enable
except for disabling outputs, which is achieved asynchronously. Input buffers,
excluding CK, CK and CKE are disabled during power-down and self refresh
modes, providing low standby power. CKE will recognizean LVCMOS LOW level
prior to VREF being stable on power-up.
CS enables(registered LOW) and disables(registered HIGH) the command
decoder.
/CS
All commands are masked when CS is registered HIGH. CS provides for external
Chip Select
bank selection on systems with multiple banks. CS is considered part of the
command code.
Row/column addresses are multiplexed on the same pins.

Latches column addresses on the positive going edge of the CLK with /CAS low.

Enables write operation and row precharge.
Latches data in starting from /CAS, /WE active.
Output with read data, input with write data. Edge-aligned with read data, centered in write data. Used to capture write data.
DM is an input mask signal for write data. Input data is masked when DM is
sampled HIGH along with that input data during a WRITE access. DM is sampled

Notes :
1. Includes ± 25mV margin for DC offset on VREF, and a combined total of ± 50mV margin for all AC noise and DC
offset on VREF, bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on VREF and
internal DRAM noise coupled to VREF , both of which may result in VREF noise. VREF should be de-coupled with an
inductance of ≤ 3nH.
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set
equal to VREF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the
pad in simulation. The AC and DC input specifications are relative to a VREF envelop that has been bandwidth limited
to 200MHZ.
5. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the dc level of
the same.
6. These charactericteristics obey the SSTL-2 class II standards.

Notes :
1.
2.
Maximum burst refresh of 8.
tHZQ transitions occurs in the same assess time windows as valid data transitions. These parameters are not
referenced to a specific voltage level, but specify when the device output is no longer driving.
3.
The specific requirement is that DQS be valid(High-Low) on or before this CK edge. The case shown(DQS going
from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was
in progress, DQS could be High at this time, depending on tDQSS.
4.
The maximum limit for this parameter is not a device limit. The device will operate with a great value for this
parameter, but system performance (bus turnaround) will degrade accordingly.

Notes :
1. OP Code : Operand code
A0 ~ A12 & BA0 ~ BA1 : Program keys. (@ MRS)
2. MRS can be issued only at all banks precharge state.
A new command can be issued after 2 CLK cycles of MRS.
3. Auto refresh functions are as same as CBR refresh of DRAM.
The automatical precharge without row precharge command is meant by "Auto".
Auto/self refresh can be issued only at all banks precharge state.
4. BA0 ~ BA1 : Bank select addresses.
If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected.
If both BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank B is selected.
If both BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank C is selected.
If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected.
If A10/AP is "High" at row precharge, BA0 and BA1 is ignored and all banks are selected.
5. During burst read or write with auto precharge, new read/write command can not be issued.
Another bank read/write command can be issued after the end of burst.
New row active of the associated bank can be issued at tRP after the end of burst.
6. Burst stop command is valid at every burst length.
7. DM sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges
(Write DM latency is 0)
