HB52RF1289E2U-75B

The HB52RF1289E2U-75B is one member of the HB52RF1289E2U series.The HB52RF1289E2U belongs to 8-byte DIMM (Dual In-line Memory Module) family, and has been developed as an optimized main memory solution for 8-byte processor applications.The HB52RF1289E2U is a 64M * 72 * 2-bank Synchronous Dynamic RAM Module, mounted 36 pieces of 256-Mbit SDRAM (HM5225405BTB) sealed in TCP package, 1 piece of PLL clock driver, 3 pieces register driver and 1 piece of serial EEPROM (2-kbit) for Presence Detect (PD).

Features of the HB52RF1289E2U-75B are:(1)3.3 V power supply; (2)clock frequency:133 MHz (max); (3)LVTTL interface; (4)Data bus width: x 72 ECC; (5)single pulsed RAS; (6)4 banks can operates simultaneously and independently; (7)burst read/write operation and burst read/single write operation capability; (8)fully compatible with:JEDEC standard outline 8-byte DIMM; (9)168-pin socket type package (dual lead out).An outline of the HB52RF1289E2U is 168-pin socket type package (dual lead out). Therefore, the HB52RF1289E2U makes high density mounting possible without surface mount technology. The HB52RF1289E2U provides common data inputs and outputs.

The absolute maximum ratings of the HB52RF1289E2U-75B can be summarized as:(1)storage temperature range:-55 to 100;(2)voltage on any pin relative to VSS:-0.5 to Vcc+0.5V;(3)supply voltage relative to VSS:-0.5 to 4.6V;(4)operating temperature range:0 to 55;(5)short circuit output current:50mA;(6)power dissipation:18.0W.Design your application so that the product is used within the ranges guaranteed by Elpida Memory, Inc.particularly for maximum rating, operating supply voltage range, heat radiation characteristics, installation conditions and other characteristics.
