MKL26Z256VMC4R IC MCU 32B 256KB

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.

## Features

### 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)

* 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

### Mixed-Signal

* Up to 16-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

### Timing and Control

* Two 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

### Human-Machine Interface

* 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

### Connectivity and Communications

* USB 2.0 On-The-Go (full-speed) with integrated USB low-voltage regulator supplies up to 120 mA off chip at 3.3 volts to power external components from 5-volts input or USB 2.0 Device (full-speed) with clock recovery feature without the need of external crystal

* FlexIO for universal or customized serial peripheral emulation

* High accuracy internal clock reference to support high performance communication

* Two I2C with DMA support, up to 1Mbps and compatible with SMBus V2 features

* One LPUART and two UART with DMA support

* Two SPI with DMA support

* I2S module for audio applications

* FlexIO module supports a wide range of protocols including UART, I2C, SPI, I2S, PWM waveform generation
