MCU combines RISC core with plenty of peripherals

Edited by the Electronicstalk editorial team Dec 10, 2002

The NEC K-line family of high performance microcontrollers is aimed at replacing traditional 16bit microcontrollers with a powerful yet cost effective RISC based solution.

Sunrise Electronics has a further addition to the NEC K-line family of high performance microcontrollers aimed at replacing traditional 16bit microcontrollers with a powerful yet cost effective RISC based solution.

The single-chip V850ES/KJ1 microcontroller is the most recent addition to NEC's new K-Line family product portfolio and comprises a 32bit RISC microcontroller with a host of on-chip features.

By offering a wide variety of memory configurations, packages and temperature ranges the K-Line family supports extraordinary scalability.

The V850ES/KJ1 is available in both mask ROM and Flash memory versions and can be powered by a wide supply voltage operating range from 2.7 to 5.5V.

It is optimised for very low power consumption and high performance.

The V850ES/KJ1 is a general-purpose device which by virtue of its large complement of onboard peripheral functions is suitable for design-in to a wide range of applications across the industrial, consumer and automotive segments.

It is especially suitable as an enhancement to classical 16bit applications by virtue of its exceptional cost/performance ratio.

Based on NEC's successful 32bit RISC CPU core, this device has a 50ns minimum instruction execution time when using a 20MHz (maximum) clock.

It offers DSP functionality with 16bit multiplication and saturation logic.

Memory configurations include 96 or 128Kbyte of MASK ROM, or 128Kbyte of Flash pus 6Kbyte of on-chip RAM.

Other built-in peripherals include a 16-channel A/D convertor with 10bit resolution, two-channel D/A convertor with 8bit resolution, and two standard UARTs as well as four three-wire serial interfaces (CSI).

A full complement of timers includes four 8bit timers, six 1-bit timers, a watch timer and two watchdog timers.

The V850ES/KJ1 family's extensive I/O capability provides a six-channel real time output port and an eight-channel key return input and a two-channel I2C option in addition to 128 standard I/O ports.

These devices can be powered by a wide supply voltage range from 2.7 to 5.5V.

Members of this family are specified over the extended operating temperature range from -40 to +85C.

Package style is 144-pin LQFP (20 x 20mm).
