Cutting the cost of hi-rel satellite devices
NEC's low-earth orbit L-Grade high-reliability devices include transistors and monolithic microwave ICs (MMICs) in both silicon and gallium arsenide (GaAs) technologies.
1Mbit SRAM retains its data at low voltages
NEC's latest 1Mbit SRAM is designed using full CMOS process memory allowing it to operate with supply currents as low as 25mA and with supply voltage 1.8-3.6V.
It combines enhanced features with NEC Electronics' latest Flash technology and meets exacting quality standards.
Moreover, it has all the advantages of NEC Electronics' proven family approach, which offers application-specific features while maintaining the high scalability that supports platform-based developments.
V850E/Dx3 is based on the 32bit RISC CPU V850 and includes application-specific peripherals such as integrated stepper motor drivers, LCD controller/driver, parallel LCD bus interface and sound generator.

Module connects any product to the Internet
NEC's V850NetChip module includes all the hardware and software necessary to connect practically any product to the Internet via LAN, ISDN or PSTN without additional design effort.
Shrinking power MOSFET switches
NEC Electronics has two new N-channel Semi-PowerMOSFET switches to meet the demand for power control in ever shrinking portable battery-powered devices.
These features make the Dx3 a good choice for driver information systems, such as instrument clusters including display and diagnostic functions.
Up to 16 A/D channels, two CAN interfaces, I2C bus, and seventeen 16bit timers complete a comprehensive feature set.
The Dx3 splits into two sub-families.
The basic version runs at 24MHz CPU speed, while the high-end version runs at 48MHz.
The family concept provides scalable memory options from 128Kbyte to 1Mbyte Flash and up to 32Kbyte RAM in a 144-pin QFP package.
With the choice of derivatives there will always be a product that is a close fit to application requirements.
This makes it easy to move up to a bigger device when memory demand rises.
With the new V850E/Dx3 family, NEC Electronics is anticipating market demand for highly integrated application-specific functions that enable customers to reduce overall system cost and development effort.
For more user-friendliness and improved driver-vehicle interaction, instrument cluster displays must integrate more and more information.
And they must present it in high-resolution colour, with clarity and flair.
The amount of specialised information - from multi-language text to graphically precise icons - being communicated is 'mushrooming' and demand for memory is rapidly increasing as a result.
The V850E/Dx3 was developed to add value to development in terms of flexibility, scalability and system cost.
The Dx3 family lets you react easily to changing requirements.
Salient benefits available with the Dx3 include reuse of core and peripheral software, pin-to-pin compatibility and standard core support.
The whole Dx3 family needs just a single tool environment.
All Dx3 controllers are qualified for the automotive temperature range (-40 to +85C).
First samples are scheduled for the first quarter of 2006.
