FRDM-K20D50M Overview
The Freescale Freedom development platform is a set of software and hardware tools for evaluation and
development. It is ideal for rapid prototyping of microcontroller-based applications. The Freescale Freedom
K20D50M hardware, FRDM-K20D50M, is a simple, yet sophisticated design featuring a Kinetis K series
microcontroller, The K family microcontroller built on the ARM® Cortex™-M4 core with DSP capabilities.
FRDM-K20D50M features a K20DX128VLH5, this device boasting a max operating frequency of 50MHz, 128KB of
flash, a full-speed USB controller, and loads of analog and digital peripherals. The FRDM-K20D50M 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 3-axis digital accelerometer, and a capacitive touch slider, and
ambient light sensor.
The FRDM-K20D50M features the Freescale open standard embedded serial and debug adapter known as
OpenSDA. This circuit offers several options for serial communications, flash programming and run-control
debugging.
