評估板S32R274EVB

The S32R274EVB evaluation board (EVB) is an evaluation tool for the S32R274 Radar MCU to enable hardware and software development.

For maximum flexibility and simplicity, the EVB has been designed as a modular development platform. The EVB main board does not contain an MCU. Instead, the MCU is fitted to an MCU daughter card (occasionally referred to as an adapter board). This approach means that the same EVB platform can be used for multiple packages and MCU derivatives within the MPC57xx and further families. High density connectors provide the interface between the EVB and MCU daughter cards as shown in the diagram below.

Both variants allow you to start with the software development, and to experience the highly integrated Radar Signal Processing Toolbox (SPT) along with state of the art functional safety and hardware security features (CSE2).

評估板S32R274EVB包括不同特性的主板和子板.

主板主要特性:

? Support provided for different MCUs by utilising MCU daughter cards
? Single 12V external power supply input with four on-board regulators providing all of the necessary EVB and MCU voltages; Power supplied to the EVB via a 2.1mm barrel style power jack or a 2-way level connector; 12V operation allows in-car use if desired
? Master power switch and regulator status LEDs
? Two 240-way high-density daughter card expansion connectors allowing connection of the MCU daughter card or a custom board for additional application specific circuitry
? All MCU signals readily accessible at a port-ordered group of 0.1” pitch headers
? RS232/SCI physical interface and standard DB9 female connector
? FlexRAY interface
? LINFlexD interface
? 2 CAN interfaces, one configurable to be connected to one out of two CAN modules, and one connected to a dedicated third CAN module
? Ethernet interface
? Variable resistor, driving between 5V and ground
? 4 user switches and 4 user LEDs, freely connectable
? Liberal scattering of GND test points (surface mount loops) placed throughout the EVB

子板主要特性:

? MCU (soldered or through a socket)
? Flexible MCU clocking options allow provision of an external clock via SMA connector or 40MHz EVB clock oscillator circuit. Solder pads on the daughter card allow selection between these external clocks. SMA connectors (including differential clock input) on CLKIN signal for easy access.
? User reset switch with reset status LED
? Standard 14-pin JTAG debug connector and 34-pin Nexus Aurora connector
? 10-pin Serial Interprocessor Interface (SIPI) connector
? Gb Ethernet Physical interface IC, with RJ45 connector
? MIPI-CSI2 connector intended for use with Eagle MR3003 RADAR front end EVK (Evaluation Kit)
? Liberal scattering of ground and test points (surface mount loops) placed throughout the EVB
