Mitsubishi Electric Launches New 16-Bit CAN Microcontrollers
SUNNYVALE, Calif.--Oct. 21, 2002--The Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., announced three new M16C(TM) Platform 16-bit microcontrollers (MCUs) designed specifically for applications requiring networking functionality in automotive and industrial markets. These new devices are members of the easy-to-use, powerful M16C family. The new flash-based MCUs have high C-code efficiency, industry-leading EMI/EMS performance, and are code compatible with other M16C Platform MCUs. In addition to the core M16C capabilities, the M16C/1N, M16C/6N4, and M16C/6N5 integrate a controller area network (CAN) function that allows designers to program and reprogram a complete network of flash-based MCUs collectively rather than individually, saving significant cost and time. They are also ideally suited to local interconnect network (LIN) automotive applications.
"By adding additional CAN family members to our proven 16-bit platform, we are increasing both customer choice and functionality," said Richard Sessions, director of embedded systems for Mitsubishi Electric & Electronics USA, Inc. "Because we have implemented a platform design concept with all of our 16-bit MCUs, our customers can easily implement the CAN option or migrate between CAN MCUs and incorporate a true electronic network without the need for expensive and time-consuming redesign."
The automotive industry is migrating toward flash MCUs as a standard requirement to improve design and manufacturing cycle times. Combining flash ROM on CAN MCUs allows manufacturers to test all electronic functions and make immediate changes if necessary. If a problem is identified, it can be remedied quickly by simple software reprogramming of the MCUs via the CAN network, significantly reducing development time. And, if a problem is identified in the manufacturing stage, the manufacturer can reprogram the system on the line without the need to scrap expensive hardware.
M16C/1N
The M16C/1N (M301N) is a CAN version of Mitsubishi Electric's M16C/10 microcontroller. Upwardly code compatible with the rest of the M16C family, the M16C/1N is a low-end 16-bit MCU with an M16C/62 central processing unit (CPU) core and 8-bit peripherals housed in a 7-mm x 7-mm, 48-pin plastic-mold LQFP package. In the automotive industry, the M16C/1N is ideal for body control and safety applications that require 16-bit power and performance at a low cost, such as anti-pinch mechanisms, occupant sensing, and remote keyless access.
M16C/6N4 & M16C/6N5
The M16C/6N4 (M306N4) and M16C/6N5 (M306N5) CAN MCUs are also built around the M16C/62 CPU and designed with high-end 16-bit peripherals. Available in a 14-mm x 20-mm, 100-pin plastic-mold QFP package, both are code and pin compatible with the M16C Platform, which is already widely integrated into automotive and industrial markets. The M16C/6N5 is equipped with one CAN module. The M16C/6N4 has two CAN modules (CAN 2.0B active), offering two network channels, and can effectively operate as a communication hub for diagnostic analysis. Both the M16C/6N4 and M16C/6N5 are ideal for applications that require more powerful 16-bit performance and network functionality, such as airbags, audio, instrument cluster, and body control systems.
Highly Reliable Flash Technology
Mitsubishi Electric's M16C flash MCUs are widely used in many "mission critical" applications including automotive safety, industrial control, communications, and computing systems. They use an extremely robust proprietary Hyper New DINOR flash technology that is not affected by process variations. This is achieved by creating memory cells with enough margin in operations and characteristics to eliminate bit failures and by setting in-process screening steps to remove defect-induced data retention failures. With tens of millions of flash devices in service, Mitsubishi Electric has received no flash ROM bit failures from the field. All M16C flash MCUs are capable of 100,000 erase/write cycles (typical).
