32bit microcontrollers include fast USB

Backwards compatibility with earlier V850ES derivatives allows the designer to continue to use existing development environments and software resources.

Available now from Gleichmann-Sunrise, 12 new 32bit microcontrollers (MCUs) from NEC Electronics execute USB 2.0 data transfers at speeds of up to 12Mbit/s.

Four of the devices, derivatives in the V850ES/JG3-U and V850ES/JH3-U lineup, provide full USB host and USB endpoint functionality.

The eight devices in the V850ES/JG3-H and V850ES/JH3 lineup are low-cost versions, providing only USB endpoint functions.

Additionally, some of the devices are equipped with a CAN interface.

With this combination, NEC Electronics takes into account the trend that CAN is increasingly used as industrial bus and in such applications USB is mostly required as connection to the PC environment.

Operation at a clock speed of 48MHz enables a computing power of up to 98MIPS.

Additional on-chip peripheral functions such as a six-phase timer with dead time generation, a fast cutoff function for motor control and an incremental counter make the MCUs not only ideally suitable for use in printers and audio systems, but also for use in industrial applications.

The backwards compatibility to earlier V850ES derivatives allows the designer to continue to use existing development environments and software resources.

Standard development tools include two special USB starter kits, an IECube for full trace and emulation, the Minicube as on-chip debugger as well as additional integrated debugger, compiler and simulator.

Samples of devices - with various memory configurations, pin counts and USB functions - in the V850ES/Jx3 family are available immediately from Gleichmann Sunrise.
