MKL03Z32CAF4R

The Kinetis KL0 MCU family is the entry point into the Kinetis L series based on the ARM Cortex -M0+ core. The KL0 ultra-low-power MCUs provide a bridge for 8-bit customers migrating into the Kinetis portfolio and is software and tool compatible with all other Kinetis L series devices.

Ultra-Low-Power

• 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
• LPUART, SPI, I²C, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core

Memory

• 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
• 8 KB ROM and built-in boot loader simplifies the effort to program MCU and allows for easy flash upgrades

Performance

• ARM Cortex-M0+ core, 48 MHz core frequency over full voltage and temperature range (-40C to +105C)
• Bit manipulation eng
