Compact Package Houses Five DDR SDRAM Chips

Housed in a 32 mm x 25 mm, 219-ball PBGA package, the WEDPND16M72S-XBX 128-MB double data rate (DDR) SDRAM reduces board space requirements by 40% compared to a discrete approach. It also offers a lower profile and reduces I/O connections by up to 19%, as well as reducing inductance and capacitance for low noise performance. The memory multichip module (MCM) is available in speeds of 200, 250 and 266 MHz and in 16M x 64 and 16M x 72 memory configurations. The DDR SDRAM chips employ a high-speed CMOS design that operates from a 2.5V supply. They are internally configured as a quad-bank DRAM with a synchronous interface. Available in commercial, industrial and military temperature range versions, the MCM is targeted for use in telecomm, datacomm and embedded applications.
