物联网时代，网络无处不在，物体无不智能。要想使物体智能，就得给他们安上处理器。很多物体很小，那么处理器也必须很小。飞思卡尔的这个处理器大概是目前最小的32位处理器了，据说最适合物联网、可穿戴应用。
这个Kinetis KL03 处理器基于ARM Cortex-M0+ 架构，可支持复杂的算法、协议栈和人机界面。它的价格仅75美分。
KL03 MCU 的特性包括：
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 ADC
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
