资料介绍

The Freescale Freedom development platform is a set of software and hardware tools for evaluation and development. It' sleal for the rapid prototyping of microcontroller-based applications. The Freescale Freedom KL26Z hardware (FRDM-KL26Z) is a capable and cost-effective design featuring a Kinetis L series microcontroller, the industry 's first microcontroller built on the ARM? Cortex?-MO+core.

FRDM-KL26Z can be used to evaluate the KL16 and KL26 Kinetis L series devices. It features a KL26Z128VLH4,a device boasting a maximum operating frequency of 48MHz,128KB of flash,a full-speed USB controller, and numerous analog and digital peripherals. The FRDM-KL26Z hardware is form-factor compatible with the Arduino? R3 pin layout, providing a broad range of expansion board options. The on-board interfaces include an RGB LED,a 6-axis digital sensor (combining a 3D accelerometer and 3D magnetometer), ambient light sensor, and a capacitive touch slider.

The Kinetis KL2x MCU family is pin, software and tool compatible with all other

Kinetis L families, and adds a Full-Speed USB 2.0 On-The-Go controller with

an integrated low-voltage regulator. The Kinetis KL2x MCU family is also

compatible with the Kinetis K20 family of MCUs built on the ARM?

CortexTM-M4 core, providing a migration path to higher performance and

feature integration. Devices start from 32 KB of flash in a small-footprint 5 x 5

mm 32 QFN package, extending up to 256 KB in a 100 LQFP/121 MBGA

package. Each family member combines ultra-low-power performance with a

with a rich suite of analog, communication, timing and control peripherals.

Kinetis KL2x MCU 主要特性:

Ultra Low Power

? Next-generation 32-bit ARM Cortex-M0+core. Two times 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 which

reduces dynamic power by placing peripherals in an asynchronous stop mode

? LPUART, SPI, I2C, ADC, DAC, LP timer and DMA support low

operation without waking up the core

-power mode

Flash and SRAM

? 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

Performance

? ARM Cortex -M0+ core, 48 MHz core frequency over full voltage and

temperature range ( –40?C +105?C)

? 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
