NEC Electronics Delivers Enhanced Design Flexibility and Performance with New 16-Bit Microcontrollers for Automotive Applications

NEC has announced expansion of 16-bit 78K0R microcontrollers (MCUs) to support automotive electronics such as window, seat and door modules; and heating, ventilation and air conditioning systems.

New 78K0R/Fx3 MCUs Deliver 16-bit Performance with 8-bit Power Consumption for Body Electronics Systems

The new products complement NEC Electronics' current F Series lineup of 8-bit and 32-bit MCUs and provide an easy scalability path for in-vehicle comfort systems. For information about NEC Electronics' automotive MCUs, visit http://www.am.necel.com/applications/automotive.

Increased Flexibility and Higher Performance for Body Electronics
To deliver faster operating and CPU speeds than NEC Electronics' 8-bit 78K0 core, the 16-bit 78K0R core employs a three-stage pipeline architecture that achieves a CPU clock speed of 24 megahertz (MHz), and executes 15 Dhrystone million instructions per second (MIPS). Additional features include expanded storage capacities, memory configurations ranging from 24 up to 256 kilobytes (KB) and an enhanced instruction set featuring 25 additional instructions.

Dual-operating data flash memory (simultaneous code execution and internal EEPROM emulation) enables engineers to reduce memory access time and simplify software design, while eliminating the need for memory banking also helps them increase operating speed and reduce system costs.
