MKL43Z128VMP4

Kinetis KL43: 48MHz Cortex-M0+ Ultra-Low Power MCU, 128KB Flash, 16KB RAM, USB, Segment LCD, 64-BGA

Overview

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

## 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, maintaining an 8-bit look and feel?

* Multiple, flexible low-power modes including new compute mode that 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 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
