Freescale Semiconductor has expanded its portfolio of 32bit kinetis microcontrollers, based on the ARM Cortex-M4 processor, with 60 latest entry-level microcontrollers. They are additions to the kinetis K10 and K20 microcontrollers and consume 630µA at a CPU speed of 4MHz in low power run mode, which is equivalent to 160µA/MHz. The low power mode consumes 40nA and the microcontrollers are suitable for space-constrained applications.
The microcontrollers are available from 32 to 128kbyte of flash memory in 32pin QFN 5x5mm to 64pin LQFP packages. The microcontrollers are built using the company's 90nm thin film storage low-leakage flash technology with up to 32kbyte of FlexMemory with 2kbyte EEPROM, low power run and stop mode currents and fast wake-up times. Peripheral options include a 16bit ADC, full-speed USB On-The-Go controller with complimentary software stack, low-power touch sensing interface and several general timing, communication and control peripherals.
The microcontrollers are suitable for a range of applications, including I/O modules for factory automation, portable healthcare instruments, USB microphones and gaming headsets, as well as smart grid applications that demand solid processing power with aggressive low-power profiles, says the company.
The microcontrollers are supported by many 32bit tools, including a package of the company's MQX RTOS and software solutions, codewarrior for microcontrollers featuring processor expert software, and a complimentary USB stack.
