Freescale shrinks world’s smallest ARM-based MCU by an additional 15 percent

by donpedro

Freescale Semiconductor announces a breakthrough addition to its Kinetis mini portfolio with the introduction of the Kinetis KL03 MCU, the world’s smallest and most

energy efficient 32-bit MCU based on ARM® technology. The Kinetis KL03 MCU builds on the previous generation Kinetis KL02 device with new features, advanced integra-tion, and greater ease-of-use – all in an even smaller 1.6 × 2.0mm2 package. The new capabilities of the Kinetis KL03 device help customers to achieve lower power in a smaller form factor, saving on product design time and cost.
Leveraging advanced wafer-level chip scale packaging, the Kinetis KL03 MCU is more than 15 percent smaller than the previous generation Freescale KL02 device, and 35 percent smaller than competing 32-bit ARM MCUs. The new SoC is ideally suited for space-constrained designs, including a wide range of applications in the consumer, healthcare, and industrial markets. It is ideal for the fast-growing Internet of Things (IoT) market, where edge nodes increasingly require more intelligence in ever-smaller form factors.
The Kinetis KL03 MCU combines the power efficiency of the Kinetis L series based on ARM® Cortex®- M0+ cores with enhanced low-power functionalities including register files, SRTC, low power UART, and additional low power wake up pins.
Additionally, the new product offers greater ease of use over the previous generation. An added ROM-based boot loader allows factory programming and on-line system firmware upgrades without adding circuitry to the board, reducing programming-related costs for customers. An internal high accurate voltage reference (Vref) delivers improved analog performance by supplying an embedded 1.2 volt reference for the ADC, enabling several use cases for applications requiring high ADC accuracy.
The Kinetis KL03 MCU integrates:
• 48 MHz ARM Cortex-M0+ core, 1.71-3.6V operation
• Bit manipulation engine for faster, more code-efficient handling of peripheral registers
• 32 KB flash memory, 2 KB RAM
• 8K ROM with on-chip boot loader
• High-speed 12-bit analog-to-digital converter
• Internal voltage reference for high ADC accuracy
• High-speed analog comparator
• Low power wake up
• Low-power UART, SPI, I2C (high speed)
• Secure real time clock
• Powerful timers for a broad range of applications including motor control
• -40 °C to +85 °C operation
