NEC Electronics Introduces V850E/RS1 Microcontroller for High-End Automotive Safety Applications

New 32-Bit Microcontroller Provides Fast Processing and Dedicated On-Board Safety Features to Ensure Real-Time Performance

March 15, 2004

KAWASAKI, Japan, DUESSELDORF, Germany, and SANTA CLARA, California: 

NEC Electronics Corporation and its subsidiaries in Europe and the United States, NEC Electronics (Europe) GmbH and NEC Electronics America, Inc., today announced the availability of their latest 32-bit microcontroller (MCU) for the automotive market, the V850E/RS1(TM). With a high-performance 40-megahertz (MHz) V850E(TM) controller core and dedicated on-board safety features, including a 10-bit 16-channel analog/digital converter (ADC) with auto discharge and diagnostic functionality, a buffered clocked serial interface (CSI), and flash memory with hardware in-circuit error correction coding (ECC), the V850E/RS1 controller is ideally suited for real-time, safety-critical automotive applications such as restraint control modules.

"NEC Electronics is a leading provider of restraint-control microcontrollers for automotive original equipment manufacturers due to the extensive application-specific features that we integrate into our products," said Yoshiyuki Idogawa, general manager, 1st Solutions Division, NEC Electronics Corporation. "By supporting these features in hardware, not just software, NEC Electronics is providing its automotive customers with higher-performing, highly reliable products."

Automotive applications such as restraint control modules require fast processing performance to deliver the real-time response needed when deploying an airbag at the instant of impact. The V850E/RS1 controller core can operate at 40 MHz and deliver 54 million instructions per second (MIPS), providing the required real-time performance. The controller's use of flash memory with hardware ECC greatly reduces the possibility of system error. Two versions of the MCU will be available, one with 256 kilobytes (K) of flash memory and 16K of random access memory (RAM), and the second with 128K of flash memory and 10K of RAM. Additionally, the V850E/RS1 MCU's buffered CSI enhances communication with ASICs in the restraint control module to further ensure error-free operation.

For customers adhering to manufacturing quality assurance processes, versions of the V850E/RS1 controller that are PPAP, AEC-Q100 and QS-9000 certified are available.

Pricing and Availability

The V850E/RS1 microcontroller is packaged in a 100-pin low quad flat package (LQFP). Pricing for the controller with 256K flash memory and 16K RAM is expected to be US$13.00 per unit in 100,000-unit quantities. Pricing for the controller with 128K flash memory and 10K RAM is expected to be US$10.00 per unit in 100,000-unit quantities. NEC Electronics will begin taking orders for engineering samples in April. Engineering samples of the V850E/RS1 MCU are scheduled to be available in July 2004 with mass production scheduled for third quarter 2005 at a production volume of 200,000 units per month. Pricing and availability are subject to change.
