CD covers full range of microcontrollers and tools
Available now free from Sunrise Electronics is a new CD featuring all the latest information on NEC's extensive range of microcontroller families and development tools.
In this way the two subfamilies provide a bridge between 8 and 32bit applications allowing designs to be upgraded or offered with a choice of performance.
The 78K0/KF1 is the largest 8bit K_Line microcontroller.
Fully backwards compatible with NEC's successful 78K0 family, it supports all the new features associated with the K_Line range (such as on-chip oscillator, clock monitor, power-on clear (POC/POR) and LIN-capable UART and thus offers full scalability.

Dedicated NEC distributor Sunrise Electronics has announced a new family of gate arrays to directly compete with FPGAs and other programmable logic devices for low- to mid-count gate array designs.
Low-fat route to embedded SoC development
New at Sunrise Electronics, System-on-Chip Lite is NEC's new approach for low- to mid-volume SoC projects for embedded control applications.
Based on an 8bit CISC CPU core, this series has hardwired instructions for bit manipulation, multiplication and division.
200ns minimum instruction cycle times are achieved with a 10MHz maximum clock frequency.
The single-chip V850ES/KF1 microcontroller is the most recent addition to NEC's new K_Line family portfolio.
With its 32bit RISC CPU it offers 50ns minimum instruction execution time using a 20MHz maximum clock and features DSP functionality with 16bit multiplication and saturation logic.
It is optimised for very low power consumption and high performance.
Offering an exceptional cost/performance ratio this device is even an excellent choice for traditional 16bit applications Both device types offer a choice of mask ROM or Flash memory and can be powered by a wide supply voltage range from 2.7 to 5.5V.
They also both offer the same extensive peripheral feature set.
This includes an eight-channel A/D convertor with 10bit resolution, two standard UARTs and three three-wire serial interfaces (CSI).
Timing facilities include four 8bit timers, two 16bit timers, a watch timer and two watchdog timers.
Extensive I/O provision includes a six-channel real time output port, an eight-channel key return input and 67 I/Os.
With this extensive integrated peripheral feature set, the KF1 series fits very well into a wide variety of applications.
This includes the industrial segment and white goods as well as automotive applications such as body electronics, LIN gateways, and so on.
Furthermore when used in combination with a software TCP/IP stack, it is also suitable for use in networking applications.
Devices are available now from Sunrise in versions either with mask ROM or Flash memory on chip.
Members of the family are specified over extended operating temperature ranges from -40 to +125C.
Package options are 80-pin LQFP and TQFP.
