Introduction
A huge range of microcontrollers as varied as the applications of the customers, from 8- to 64-bit devices, from CISC to RISC, with CAN, VAN or J1850 interfaces, with Flash, Mask ROM or ROM-less, is offered by NEC.
- Microcontroller Overview
- 78K Family (8/16-bit)
- V850 Family (32-bit)
Types of Automotive Controllers
An attractive 4 bit to 64 bit microcontroller and microprocessor product lineup is offered by NEC.
The powerful development environment and the solutions for strong support to the product development are also provided by NEC.
78K Core
NEC Electronics' mainstream 8-bit core is the 78K0 core today. Without the performance needs of the 78K0, the 78K0S core was derived for cost-sensitive applications. So, the 78K0S is used mainly for very small devices.
The 78K family is the newest addition to the 16-bit 78K0R core. It is also based on the 78K0. It provides real 16-bit performance because of its 16-bit-wide data bus and 16-bit-wide ALU.
V850 Core
The original V850 core is the ancestor of all of NEC Electronics' 32-bit microcontrollers. It is no longer used for new microcontroller designs since its successors, the V850ES and V850E1/E2 cores, are readily available.
An ideal choice for applications is the V850ES as it is optimized for lowest costs, often served by 16-bit microcontrollers. The V850E1 core was designed for high performance, to complement this. Its successor, the V850E2, pushed the performance bar even further later.
