NEC Electronics, represented by Soanar , have expanded their line-up of 16-bit 78K0R microcontrollers (MCUs) to support cost-sensitive automotive applications. Based on NEC Electronics' fast and efficient 78K0R core, the new 78K0R/Fx3 MCUs are optimised to deliver higher performance and expanded memory options for automotive body electronics applications such as window, seat and door modules; and heating, ventilation and air conditioning (HVAC) systems.
The new products complement NEC Electronics' current F Series line-up of 8-bit and 32-bit MCUs and provide an easy scalability path for in-vehicle comfort systems. These MCUs provide 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.
In addition to supporting the controller area network (CAN) protocol, the new NEC Electronics MCUs also offer extended Local Interconnect Network (LIN) support with automatic baud rate detection and enhanced timer functionality. This allows engineers to reduce software overhead, and simplify LIN and complex timer design in increasingly sophisticated body electronics systems.
Features:
- 16-bit CPU Core Clock Frequency up to 24MHz/15MIPS
- 24kB to 256kB Flash supporting EEPROM Emulation
- CAN Controller
- UARTs with LIN support
- 30-pin to 100-pin in QFN, QFP and SSOP Packages
