ATP AL24P72L8BLK0M
8GB DDR3-1600 REGISTERED ECC DIMM
DESCRIPTION
The ATP AL24P72L8BLK0M is a high performance 8GB DDR3-1600 Registered ECC SDRAM memory
module. It is organized as 1024M x 72 in a 240-pin Dual-In-Line Memory Module (DIMM) 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.

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.

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.

Notes:
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.
2. Failures per Billion Device-Hours
