|Freescale Introduces Kinetis KL02, World’s Smallest ARM Powered® Microcontroller|
1.9 x 2.0 mm MCU enables new wave of product miniaturization for the Internet of Things
Measuring just 1.9 x 2.0 mm, the Kinetis KL02 MCU is 25 percent smaller than the industry’s next-smallest ARM® MCU. Within this miniscule device, Freescale has included the latest 32-bit ARM Cortex™-M0+ processor, cutting-edge low-power functionality and a range of analog and communication peripherals. This enables system designers to dramatically reduce the size of their boards and products while retaining the all-important performance, feature integration and power consumption characteristics of their end devices. In addition, space-constrained applications that previously couldn’t incorporate an MCU now can be upgraded to become smart applications, adding a new tier of devices to the IoT ecosystem.
“Freescale has been a pioneer in many aspects of the ARM Powered MCU
market with our Kinetis portfolio,” said
“The Internet of Things will soon be a vast and diverse ecosystem of
smart connected devices and screens that embed intelligence into many
new areas of our lives. This could range from tiny sensors helping to
monitor crops and deliver irrigation, to microcontrollers that enable
entire buildings to be more energy efficient. Our mobile devices could
be soon controlling and managing this data and making our lives easier
to manage," said
Advanced chip-scale packaging
The Kinetis KL02 is a wafer-level chip-scale package (CSP) MCU. Freescale’s CSP MCUs use the latest in package manufacturing technology to connect the die directly to the solder ball interconnects and, in turn, to the printed circuit board (PCB). This removes the need for bond wires or interposer connections, which minimizes die-to-PCB inductance and improves thermal conduction and package durability for physically harsh environments. The KL02 device is the third CSP MCU in the Kinetis portfolio, joining the larger 120/143-pin Kinetis K series K60/K61 variants. Additional Kinetis CSP MCUs with increased performance, memory and feature options are planned throughout 2013.
Energy efficiency and feature integration
Building upon the energy efficiency of the Cortex-M0+ core, the Kinetis KL02 MCU reduces the power consumption threshold of the Kinetis L series to an even lower entry point and is ideal for the demanding power profiles of miniaturized, IoT-linked systems. The ultra efficient KL02 delivers 15.9 CM/mA* and, like the other Kinetis MCUs, it includes autonomous, power-smart peripherals (in this case, an ADC, UART and timer), 10 flexible power modes and wide clock and power gating to minimize power loss. A low-power boot mode reduces power spikes during the boot sequence or deep sleep wake-up. This is useful for systems in which battery chemistry limits the allowable peak current, such as those employing lithium-ion batteries frequently used in portable devices.
Kinetis KL02 MCU features include:
Freescale will demonstrate the energy efficiency of the L-series
microcontrollers and have samples of the Kinetis KL02 CSP at
Availability and enablement
The Kinetis KL02 CSP MCU is expected to begin sampling to lead customers
The new FRDM-KL02 Freescale Freedom development platform and accompanying Freescale and third-party enablement support will also be available in July. Customers can start development with the FRDM-KL05Z Freescale Freedom development platform in late March. This contains the superset Kinetis KL05 MCU and provides access to the core, key peripherals and Freescale and third-party enablement.
