MKL26Z128VLH4R

The Kinetis KL2x is an ultra-low-power MCU family that adds a full-speed USB 2.0 On-the-Go (OTG) controller or a full-speed crystal-less USB 2.0 device controller in addition to the Kinetis KL1x series. The Kinetis KL2x MCU family is compatible with Kinetis K20 MCUs (based on ARM Cortex -M4), and with all other Kinetis KL1x, KL2x, KL3x, and KL4x series MCUs, providing a migration path to lower and higher performance and feature integration.

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, FlexIO, ADC, DAC, LP timer and DMA support low-power mode operation 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)
