Freescale announces world’s smallest ARM chip

March 7, 2013 in News by admin

Freescale introduces the Kinetis KL02 chip-scale package (CSP), the world’s smallest ARM Powered® MCU. Available in the ultra-small 1.9 mm x 2.0 mm wafer level chip-scale package, the KL02 CSP (MKL02Z32CAF4R) drastically reduces board space while retaining rich MCU feature integration. The KL02 CSP consumes 25 percent less PCB area, yet delivers 60 percent more GPIO than the nearest competing MCU.

The Kinetis KL0 family is the entry point into the low-power Kinetis L series MCUs based on the ARM® Cortex™-M0+ processor, delivering 32-bit performance with class-leading code density, integrated flash memory, precision analog, connectivity and timers.


  • Next-generation 32-bit ARM Cortex-M0+ core: 2x more CoreMark/mA than the closest 8/16-bit architecture
  • Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, keeping an 8-bit “look and feel”
  • Multiple flexible low-power modes, including new compute clocking option which reduces dynamic power by placing peripherals in an asynchronous stop mode
  • LPSCI, SPI, I2C, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core
  • Up to 32 KB flash with 64 byte flash cache, up to 4 KB RAM
  • Security circuitry to prevent unauthorized access to RAM and flash contents
  • ARM Cortex-M0+ core, 48 MHz core frequency over full voltage and temperature range (-40ºC to +105ºC)
  • Bit manipulation engine for improved bit handling of peripheral modules
  • Thumb instruction set combines high code density with 32-bit performance
  • Up to 4-ch. DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
  • Independent-clocked COP guards against clock skew or code runaway for fail-safe applications
  • 12-bit ADC with configurable resolution, sample time and conversion speed/power
  • Integrated temperature sensor
  • High-speed comparator with internal 6-bit DAC
  • 12-bit DAC with DMA support
  • One 6-ch. and one 2-ch. 16-bit low-power timer PWM modules with DMA support
  • 2-ch., 32-bit periodic interrupt timer provides time base for RTOS task schedule or trigger source for ADC conversion
  • Low-power timer allows operation in all power modes except for VLLS0
  • Real-time clock with calendar
  • Capacitive touch sense interface supports up to 16 external electrodes and DMA data transfer
  • GPIO with pin interrupt support, DMA request capability and other pin control options
  • I2C with DMA support, up to 100 kbps and compatible with SMBus V2 features
  • LPUART and SPI with DMA support
