Freescale addresses high noise applications with new Kinetis mcu family
1 min read
Looking to provide a 32bit alternative to those designing 8bit microcontrollers into white goods and industrial products, Freescale has launched the Kinetis E series. The mcus, based on the ARM Cortex-M0+ core, are 5V tolerant and offer high noise immunity.
Said to be suited to use in applications such as building control systems, motor control fans, industrial converters and similar equipment, devices in the E series are supplied in large pitch packages and feature high electrostatic discharge protection. This combination, says the company, can enable single layer pcbs and lower system cost.
"Historically, 32bit mcus have been associated with lower voltage operation and considered unreliable in electromagnetically harsh environments, such as factories or even many households," said Brandon Tolany, vice president of marketing and business development for Freescale's mcu business. "Kinetis E series mcus break new ground by combining low cost and high performance with advanced emc and esd protection features designed to support compliance with industrial grade reliability and temperature requirements."
Initially, Freescale is launching the KE02 range as the 'entry point' into the E series. There are 10 variants available, with 16kbyte to 64kbyte of flash and 2kbyte or 4kbyte of sram. With a maximum clock rate of 20MHz, the parts feature 256byte of eeprom and a 12bit a/d converter. Packaging choices are 32, 44 and 64pin lqfp.
