MKL33Z256VLH4

The Kinetis KL3x MCU family combines ultra-low power performance with a rich suite of analog, communication, timing, and control peripherals for consumer and industrial metering applications. Adds a segment LCD controller option to the Kinetis KL1x series Includes multiple, flexible low power modes including new compute mode that reduces dynamic power by placing peripherals in an asynchronous stop mode Provides a migration path to lower or higher performance and feature integration through compatibility with other Kinetis MCUs 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, 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 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 en"
