|Assessing ESD Sensitivity of Interface IP Using Charged Device Model|
An electronic device is susceptible to Electrostatic Discharge (ESD) damage during its entire life cycle. Due to the rapid growth in automated handling, manufacturing and assembly of electronic devices, CDM has become the primary real world ESD test model. This white paper describes the CDM ESD event and explains how IC designers can obtain actual CDM voltage levels of an SoC using the peak current level measured during the interface IP CDM qualification phase.

|Three Power Saving Techniques Using PCI Express IP|
The increasing data traffic between devices in a computing application environment is causing a large power footprint and for that reason designers are looking for ways to lower the power consumption of their SoCs during sparse or idle times. The smaller, battery-powered devices are often idle and in deep sleep modes, but these deep power saving modes come at the cost of slow resume times to switch back to normal operating mode. This paper uses PCI Express IP as an example to describe three power saving techniques and how designers are using the protocol’s and design tools’ power management features to deliver power-efficient SoCs for devices requiring fast resume times.

|High Performance and Scalable Sensor Connectivity with MIPI I3C|
The MIPI® Alliance is working on a new standard called I3C (or SenseWire) that incorporates and unifies key attributes of I2C and Serial Peripheral Interface (SPI). MIPI I3C enhances the capabilities and performance of each approach with a comprehensive, low pin count and scalable interface as well as architecture. It supports sensor interface architectures that mobile, mobile-influenced, and embedded-system applications anticipate to require in the near future. This paper describes the MIPI I3C specification and its key benefits for a seamless transition from I2C to I3C.

|Optimizing LPDDR4 Performance and Power with Multi-Channel Architectures|
LPDDR4 offers huge bandwidth in a physically small PCB area and volume; up to 25.6 GByte/s of bandwidth at a 3,200 Mbps data rate from a single 15mmx15mm LPDDR4 package when two dies are packaged together. LPDDR4 builds on the success of LPDDR2 and LPDDR3 by adding new features and introducing a major architectural change. This white paper discusses why designers are selecting LPDDR4, how to handle 2-die and 4-die packages with multi-channel connections, the advantages of sharing channels through system-on-chip (SoC) partitioning, and how to optimize channels for the lowest power consumption.

|Addressing Three Critical Challenges of USB Type-C Implementation|
As designers create new products and system-on-chips (SoCs) with USB Type-C support, they need to be aware of partitioning challenges. The SoC and system design must be partitioned to support the specification’s requirements for precision analog circuitry plus high voltage/high current switches, and Type-C management software must be partitioned to execute on the processor, internal microcontroller, microcontroller in a power management IC, and/or on an external dedicated USB Type-C chip. This white paper describes key challenges and suggests solutions for designers of USB Type-C products and SoCs with native USB Type-C support.

|Reliability, Availability and Serviceability (RAS) for Memory Interfaces|
Smaller process geometries and higher Double Data Rate (DDR) Dynamic Random Access Memory (DRAM) interface speeds are driving demand for new and more robust techniques for preventing, repairing and detecting memory errors. Some of these techniques are enabled by features in the latest DDR4 and DDR3 RDIMM standards, and others can be applied to any DRAM type. Collectively these techniques improve the Reliability, Availability, and Serviceability (RAS) of the computing system that adopts them. This white paper reviews some of the ways that errors can occur in the DDR DRAM memory subsystem and discusses current and future methods of improving RAS in the presence of these errors.
