Freescale Semiconductor is now offering alpha samples of its Kinetis L series built on the ARM Cortex-M0+ processor. With the Kinetis L series, Freescale provides the ideal opportunity for users of legacy 8- and 16-bit architectures to migrate to 32-bit platforms and bring additional intelligence to everyday devices without increasing power consumption and cost or sacrificing space. Applications, such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control, can now leverage 32-bit capabilities and the scalability needed to expand future product lines – all at 8- and 16-bit price and power consumption levels.
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 (mode and can rapidly wake from a reduced power state, process data and return to sleep, extending application battery life. These advantages are demonstrated in the FTF demo, which compares the energy-efficiency characteristics of the Kinetis L series against solutions from Freescale competitors in a CoreMark benchmark analysis. The Kinetis L series is also part of the Freescale Energy-Efficient Solutions program.
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.
