Recently, NEC introduced twelve new 32-bit microcontrollers with integrated USB functionality. The V850ES/JG3-H, V850ES/JH3-H, V850ES/JG3-U, and V850ES/JH3-U microcontrollers execute high speed USB 2.0 data transfers up to 12 Mbps. The USB-ready microcontrollers are suitable for development of applications that require USB connectivity and 32-bit processing power. Applications of these new microcontrollers includes: real-time control of industrial equipment, factory automation systems, medical devices, point-of-sales terminals, telecommunications, and testing and measurement devices, and also consumer electronics products.

NEC’s new 32-Bit USB-ready Microcontrollers

NEC’s new 32-Bit USB-ready Microcontrollers:

V850ES/JG3-H Microcontrollers:
- µPD70F3760
- µPD70F3761
- µPD70F3762
- µPD70F3770
V850ES/JH3-H Microcontrollers:
- µPD70F3765
- µPD70F3766
- µPD70F3767
- µPD70F3771
V850ES/JG3-U Microcontrollers:
- µPD70F3763
- µPD70F3764
V850ES/JH3-U Microcontrollers:
- µPD70F3768
- µPD70F3769

The new USB-microcontrollers are all based on NEC’ 32-bit V850ES core. The core offers fast execution of instructions per clock cycle at 1.9 Dhrystone MIPS per MHz, efficient RISC CPU core with five-stage pipeline and CISC instructions.

Shigenobu Ishikawa, NEC Electronics, said:

We are seeing an increased demand for microcontrollers that can deliver the higher performance and greater functionality required in systems that are growing ever more complex… USB is arguably the most popular and successful interconnect technology available today, and NEC Electronics’ new 32-bit microcontrollers now make it easier than ever for designers to add USB capabilities to their target systems…

The four chips in the V850ES/Jx3-U lineup provide both USB host and function capability, while the eight chips in the V850ES/Jx3-H lineup provide USB function capability only. All of the new devices have the same instruction set and development environment as other V850-based cores, making it easy for designers to migrate from one V850 core to another.

Operation at a clock speed of 48 MHz enables the chips to execute 98 million instructions per second (MIPS). Like NEC Electronics’ general-purpose V850ES/JG3 and V850ES/JJ3 microcontrollers, the new products also feature on-chip peripheral functions such as a motor control timer and real-time counter that simplify system design and contribute to lower component counts and smaller board sizes.

NEC Electronics is working with partners to provide USB drivers for the host and function controllers. Standard development tools include NEC Electronics’ IECUBE full-function emulator, MINICUBE on-chip debugger and integrated debugger, compiler and simulator. Two dedicated USB starter kits with basic and advanced functionality, including application drivers, are expected to be available June 2008.
