32-bit Flash Microcontrollers (ESC Booth 306)

STMicroelectronics (Mansfield, TX) has released the STM32 Family of 32- bit Flash microcontrollers based on ARM® Cortex™—M3 core. The STM32 is offered in the STM32F103 performance line, with 72 MHz clock frequency for 32- bit devices, and the STM32F101 Access line, with 36 MHz clock frequency for 16- bit devices. Both lines offer 32K to 128K of embedded Flash memory. At 72 MHz executing from Flash, the STM32 consumes only 36mA.

Java Object-Oriented Embedded Database (ESC Booth 839)

McObject® (Issaquah, WA) has released Perst™, its all-Java object-oriented, open source embedded database that is compatible with the Android mobile device platform. Perst stores data directly in Java objects, eliminating the need for data-packing or unpacking code to map between the application's data model and the database's data model. Perst is a compact embedded database, with a core of only five thousand lines of code. This small footprint imposes little demand on system resources. Perst does not require administration and it supports transactions with the ACID (Atomic, Consistent, Isolated and Durable) properties.

Protection Schemes for Advanced Shipboard Electrical Systems

A research program has made progress toward the development of schemes for protection against faults in next-generation DC zonal shipboard electrical systems (DC SESs) and for configuration management in these systems to enable surviving parts of the systems to continue to distribute electric power to critical loads. Computational simulations of a representative prototype DC SES have shown that these schemes could afford protection at a system level (in contradistinction to a local level), thereby imparting, to the DC SES, an intended capability for self-healing.

DC Power Converter for 200°C Containing SiC Transistors

A DC-to-DC power converter, nominally rated for a power of 180 W, an input potential of 28 V, an output potential of 270 V, and a maximum operating temperature of 200°C has been designed, built, and tested. This power converter serves as a prototype for further development of power converters required to be capable of operating in high-temperature environments in diverse settings, including automobile, aircraft, and spacecraft engines, and oil and gas wells.

A Comparison of SiC-Based Devices for Use as Power Switches

A report details a survey of the state of technological development and commercial availability of SiC-based electronic devices that has been performed to evaluate the suitability of such devices as power switches in present and future applications in which high reliability and/or capability for high-temperature operation are or will be required. Examples of such applications include high-temperature motor drives, switch modules, and DC-to- DC power converters, and DC-to-AC power inverters. The survey consisted primarily of a comparative study of the relative advantages and disadvantages of SiCbased vertical-junction field-effect transistors (VJFETs) and SiC-based metal oxide/semiconductor field-effect transistors (MOSFETs). Other devices, including conventional Si-based MOSFETs and SiCbased bipolar junction transistors (BJTs) were considered, but only in passing, because it was assumed, at the beginning of the study, that the superiority of SiCbased VJFETs and SiC-based MOSFETs over other devices for power-switching applications had already been established.
