DESCRIPTION
The ATP AW24P7228BLK0M is a high performance 8GB DDR3-1600 Unbuffered ECC SODIMM SDRAM
memory module. It is organized as 1024M x 72 in a 204-pin Small Outline Dual-In-Line Memory Module
(SODIMM) package. The module utilizes eighteen 512Mx8 DDR3 SDRAMs in FBGA package. The module
consists of a 256-byte serial EEPROM, which contains the module configuration information.

ABSOLUTE MAXIMUM DC RATINGS
Item Symbol Rating Units Notes
Voltage on VDD pin relative to VSS V
DD -0.4V ~ 1.975V V 1
Voltage on VDDQ pin relative to VSS V
DDQ -0.4V ~ 1.975V V 1
Voltage on any pin relative to VSS V

Storage Temperature TSTG -55 to +100
oC 1
Operating Temperature TCASE 0 to +95 oC 1,2,3
Note:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
2. It is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard.
3. At 85 - 95 oC operation temperature range, doubling refresh commands in frequency to a 32ms period ( Refresh interval =3.9 µs ) is required, and to enter
to self refresh mode at this temperature range, an EMRS command is required to change internal refresh rate.

Input Low Voltage (AC) VIL (AC) - - VREF - 0.135 V
Note:
1. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the value of VREF is expected to be about 0.5 x
VDDQ of the transmitting device and VREF is expected to track variations in VDDQ.
2. Peak to peak AC noise on VREF may not exceed 2% VREF (DC).
3. VTT of transmitting device must track VREF of receiving device.
4. AC parameters are measured with VDD, VDDQ and VDDL tied together.

Note:
1. The Mean Time between Failures (MTBF) is calculated using a prediction methodology, Bellcore Prediction, which based on reliability data of the individual
components in the module. It assumes nominal voltage, with all other parameters within specified range.

TIMING PARAMETER
1:Unit ’nCK’ represents one clock cycle of the input clock, counting the actual clock edges.
2: For devices supporting optional downshift to CL=7 and CL=9, tAA/tRCD/tRP min must be 13.125 ns or lower. SPD settings must be programmed to match.
