MKL43Z128VMP4

The Kinetis KL4x MCU family combines ultra-low-power performance with a rich suite of analog, communication, timing and control peripherals (including a segment LCD controller) for applications like electronic scales, flow meters, smart meters, and thermostats. Includes multiple flexible low-power modes, including new compute mode which reduces dynamic power by placing peripherals in an asynchronous stop mode Features security circuitry to prevent unauthorized access to RAM and flash contents Provides a migration path to lower and higher performance and feature integration through compatibility with other Kinetis families Backed by robust development tools and software

Ultra-Low-Power

• Next-generation 32-bit ARM Cortex™-M0+ core: 2x more CoreMark/mA than theclosest 8/16-bit architecture.
• Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, maintaining an 8-bit “look and feel”
• Multiple, flexible low-power modes including new compute mode that reducesdynamic power by placing peripherals in an asynchronous stop mode
• LPUART, SPI, I²C, ADC, DAC, LP timer and DMA support low-power modeoperation without waking up the core

Memory

• Up to 256 KB flash with 64 byte flash cache, up to 32 KB RAM
• Security circuitry to prevent unauthorized access to RAM and flash contents
• 16 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 (-40ºC to +105ºC)
• Bit manipulation engine
