Freescale Expands Ultra-Low-Power MCU Portfolio with New Kinetis KL17/27 32/64KB MCUs

AUSTIN, Texas – Freescale Semiconductor has expanded its Kinetis L series with the new KL17 and KL27 ARM® Cortex®-M0+-based MCUs, combining low-power analog and connectivity features with ultra-small packaging options.
The USB-enabled Kinetis KL27 device, together with the general purpose KL17 product, extend the Kinetis L series to more than 200 offerings and bring scalable design options to applications such as portable medical devices and remote sensing equipment.

Power consumption figures are 46µA/MHz in low power run mode, 1.68µA in stop mode with full RAM retention and RTC enabled, and 87nA in low leakage stop mode. The Kinetis KL27’s full-speed USB controller supports crystal-less operation and includes a ‘Keep Alive’ function. This allows it to remain active in very low power stop mode, then wake up without the need to re-enumerate, making it ideal for low-power USB peripherals. Both offerings include a ROM-based bootloader, 16-bit ADC and Flex/IO module for PWM signal generation and UART/ SPI/IIC protocol emulation.
