Freescale Reveals Tiny ARM-Based Kinetis L Microcontrollers
The ARM Cortex-M0+ processor consumes approximately one-third of the energy of any 8- or 16-bit processor available today, while delivering between two to 40 times more performance. The Kinetis L series supplements the energy efficiency of the core with the latest in low-power MCU platform design, operating modes and energy-saving peripherals. The result is an MCU that consumes just 50 uA/MHz* in very-low-power run (VLPR) mode and can rapidly wake from a reduced power state, process data and return to sleep, extending application battery life. Kinetis L series energy-saving peripherals do more with less power by maintaining functionality even when the MCU is in deep sleep modes. In traditional MCUs, the main clock and processor core must be activated to perform even trivial tasks such as sending or receiving data, capturing or generating waveforms or sampling analog signals. Kinetis L series peripherals are able to perform these functions without involving the core or main system, drastically reducing power consumption and improving battery life.
Features common to the Kinetis L series families include:
- 48 MHz ARM Cortex-M0+ core
- High-speed 12/16-bit analog-to-digital converters
- 12-bit digital-to-analog converters
- High-speed analog comparators
- Low-power touch sensing with wake-up on touch from reduced power states
- Powerful timers for a broad range of applications including motor control
- Kinetis L0 family – the entry point into the Kinetis L series. Includes eight to 32 KB of flash memory and ultra-small 4mm x 4mm QFN packages. Pin-compatible with the Freescale 8-bit S08P family. Software- and tool-compatible with all other Kinetis L series families.
- Kinetis L1 family – with 32 to 256 KB of flash memory and additional communications and analog peripheral options. Compatible with the Kinetis K10 family.
- Kinetis L2 family – adds USB 2.0 full-speed host/device/OTG. Compatible with the Kinetis K20 family.
The Kinetis L series is pin- and software-compatible with the Kinetis K series (built on the ARM Cortex-M4 processor), providing a migration path to DSP performance and advanced feature integration. Kinetis L series alpha samples are available now, with broad market sample and tool availability planned for Q3. Pricing starts at a suggested resale price of 49 cents (USD) in 10,000-unit quantities. The Freescale Freedom development platform is planned for Q3 availability at a suggested resale price of $12.95.
