2.2 Short Description

The miriac

EK-5744 is a functional safety evaluation kit, based on the NXP

MPC5744P MCU.

It provides a solid base for custom developments and shows how to use the

MPC5744P for devices meeting any of the standards IEC 61508/62061 (up to SIL3),

ISO 13849 categories 1 and 2 and performance levels a-d or similar.

Typical applications for devices based on the MPC5744 will run in the fields of man-

ufacturing systems engineering, plant engineering, transportation, automotive and

avionics where safety standards as shown above have to be implemented.

The MPC5744P microcontroller consists of two e200z4 Power Architecture cores

running in delayed lockstep mode. Each of these two cores monitors and supervises

the other. Additionally, the MCU implements system-wide error detection strategies.

The EK-5744 provides analog and digital inputs and outputs which have been im-

plemented following the safety requirements of IEC 61508 and ISO 13849. Single-

channel architecture is provided for lower safety requirements, dual-channel archi-

tecture will allow you to even fulfill higher safety requirements.

For safety related communication (e.g. via CANopen safety) you may use a redun-

dant CAN interface. This interface may also be used for non-safety-related

communication.

For integration into a network the board provides a 10/100MBps Ethernet interface

(RJ45). Utilizing an appropriate protocol stack, this interface may also be used for

safety-related communication (e.g. using openSAFETY or SoE). In addition to that,

the evaluation kit EK-5744 allows full access to all MCU signals. This gives you the

opportunity to enhance the EK-5744 with your own functionality.

The EK-5744 is shipped with a firmware. This firmware contains safety functions and

an API (“application programming interface”) used to access the MCU and EK-5744

features. Using this firmware and API makes it easier for you to build your own de-

vices conforming to the safety standards IEC 61508/62061 and ISO 13849.
