High-speed registers take control of
memory
Philips has developed a new family of high-speed registers for memory-intensive applications such as high-end servers and advanced computing.
As memory modules have evolved from slower single datarate (SDR) solutions to double datarate (DDR), the need for increasingly precise signal control has led to the increased use of registers To address this design need, Philips has developed a new family of high-speed registers for memory-intensive applications such as high-end servers and advanced computing

High security for smart card MCU family
Philips Semiconductors describes SmartMX as the world's first ultra-low-power cost-optimised high-performance family of smart card controller ICs.
Optimised for DDR2 DIMM loads, the new registers maximise DDR2 registered memory module performance by precisely controlling the signals going to each DRAM on the module.
The memory module market is evolving toward the higher DDR2 speeds, a trend that requires registers to be optimised for speed and signal integrity.
Many millions of DDR2 modules will be manufactured in 2005, and a significant percentage of them will be registered modules.

Class D family provides single-chip audio
Philips Semiconductors has boosted the home audio market, launching a series of single-chip Class D audio amplifiers.
Philips' registers are ideal for customers who require advanced and reliable performance, as they offer the highest speeds available with 1.8ns maximum propagation delay time (tPD), thereby exceeding industry standards for improved margin and high-speed operation.
Two of the new devices also feature a parity checking function for increased reliability.
All the new products support or exceed the DDR2 standard defined by the Joint Electronic Device Engineering Council (JEDEC), ensuring compatibility with memory solutions from all major manufacturers.
"By providing one of the fastest available single die solutions, as well as including innovative features such as the parity checking, Philips enables us to create sophisticated, high-density low-profile memory module solutions in a wide range of configurations", said Ken Kledzik, Executive Vice President and CTO at Legacy Electronics, a leading manufacturer of memory modules.
"Many of these are high-speed, highly-packed modules that utilise up to 36 DDR2 SDRAMs and incorporate our patented Canopy technology".
"As the performance requirements of workstations and servers increase, memory manufacturers need to develop solutions that operate at ever-faster speeds", said Pierre-Yves Lesaicherre, General Manager, Interface Products Business Line at Philips Semiconductors.
"Designed to help computing companies and module makers meet this requirement, Philips' new registers set the bar in terms of speed, signal integrity and feature innovation".
All the new devices are single die solutions, reducing the overall cost by avoiding hybrid assembly techniques and ensuring reliability.
The products are available in either leaded or lead-free packaging in order to meet various customer requirements.
All three new products support DDR2-400, DDR2-533 and DDR2-667, and are available now.
The SSTU32864 comes in LFBGA-96 packaging and is used on DDR2 modules with up to 18 DRAMs.
The SSTU32866, featuring a parity checking function, also comes in LFBGA-96 packaging and is used on DDR2 modules with up to 18 DRAMs.
The SSTU32865 is used in more complex, typically stacked modules that have up to 36 DRAMs per module.
Packaged in 160-ball TFBGA, the SSTU32865 also includes a parity checking function.
