Addressing the growing demand for greater automation of in-vehicle comfort and safety systems, NEC Electronics today introduced 13 new 32-bit V850ES/Fx3-L microcontrollers (MCUs) that offer increased functionality at a low cost for automotive body and safety applications. As members of NEC Electronics’ F Series MCUs, the new 32-bit devices provide the price/performance ratio required for anti-theft mechanisms, climate control systems, airbags, hands-free systems and small thin-film-transistor (TFT) products.

New applications for in-vehicle comfort and safety are driving the need for electronic control units that provide greater levels of functionality and performance within prescribed pricing constraints. NEC Electronics’ new 32-bit MCUs deliver that design flexibility and increased performance in a cost-effective, reliable solution.

NEC Electronics’ 0.15-micron process technology enables the new V850ES/Fx3-L devices to execute 29 Dhrystone MIPS (DMIPS) at a clock speed of 20 MHz. Flash ROM ranges from 64 to 256 kilobytes (KB) with RAM ranging from 6 to 12 KB, and the devices come in 64-, 80- or 100-pin packages that are pin-compatible with NEC Electronics’ previous-generation V850ES/Fx2™ devices, making migration to the new devices seamless and fast.

The new V850ES/Fx3-L MCUs are software and hardware compatible with NEC Electronics’ higher-performing V850ES/Fx3™ devices in order to provide a migration path for future system changes. In addition, all V850ES/Fx3 and V850ES/Fx3-L devices share the same hardware and software development tools.

In total, NEC Electronics now offers 29 V850ES/Fx3 MCUs for automotive control applications, giving customers greater product options and more design flexibility. All devices support the controller area network (CAN) and local interconnect network (LIN) protocols.
