1 Overview
The NXP MC56F80000 Evaluation Kit board (MC56F80000-EVK) is a simple, yet
sophisticated design featuring the MC56F80748 digital signal controller (DSC), a
device that combines the processing power of a digital signal processor (DSP) and the
functionality of a microcontroller (MCU).
The MC56F80xxx device family is based on a 32-bit 56800EF core with:
•Up to 100 MIPS at 100 MHz core frequency
•DSP and MCU functionality in a unified C-efficient architecture
•Enhanced single-precision floating-point unit (eFPU)
•Coordinate rotation digital computer (CORDIC) engine
MC56F80748 has 64 kB on-chip Flash memory and 8 kB on-chip RAM.
The MC56F80000-EVK board features OpenSDA, which provides an onboard debugger
(consider it as an on-chip Multilink debugger) and a virtual serial port for rapid prototyping
and product development. On MC56F80000-EVK, the OpenSDA MCU is a Kinetis K
Series K26 family device, MK26FN2M0VMI18.
The MC56F80000-EVK hardware is form-factor compatible with the Arduino™ R3 pin
layout, providing a broad range of expansion board options. The onboard interface
includes a 3-axis MEMS accelerometer, PWM and user LEDs, buttons, ADC test circuits,
OPAMP test circuits, and external serial flash memory.
This document provides detailed information about the MC56F80000-EVK board
interfaces, power supplies, clocks, LEDs, and other interfaces.
