2. EVB Features
The EVB provides the following key features:
•
MCU Socket supporting the 208BGA production package and the 256BGA development package.
•
Single 12-14V external power supply input with on-board regulators to provide all of the necessary
EVB and MCU voltages. Power may be 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.
•
Flexible on-board power supply configuration with the option to bypass the internal MCU regulators if
desired.
•
Master power switch and regulator status LED’s – Regulators connected to the ADC to allow
monitoring.
•
User reset switch with reset status LED’s
•
User configurable Low Voltage Inhibit to monitor the status of the 3.3V and 5V regulators.
•
Control of the BOOTCFG status via a dedicated jumper.
•
Flexible MCU clocking options:
40MHz Oscillator Crystal
32Khz Watch Crystal
SMA connector to allow external clock support
8Mhz Oscillator circuit.
•
SMA connector on MCU-CLKOUT signal for easy access.
•
Standard 14-pin ONCE debug connector and 38-pin MICTOR Nexus connectors.
•
All MCU signals are accessible on port-ordered groups of 0.1” pitch headers.
•
DSPI A signals can be routed to a set of shift registers to allow a 32-bit phantom port to be created.
•
SCI channels A and B can be routed to a standard DB9 female connector (PC RS-232 compliant) via
a Maxim physical interface.
•
SCI channels C and D can be routed to LIN interface header (0.1”) and molex connectors, both will
full physical transceivers.
•
FlexCAN channels A and B can be routed to 0.1” headers and DB9 connector via a Philips high speed
CAN transceiver which supports both 3.3V and 5V inputs.
•
FlexCAN channels C, D, E and F are routed to the prototyping area with DB9 connectors to allow
additions CAN physical interfaces to be easily integrated.
•
User prototyping area consisting of a 0,1” grid of through hole pads with easy access to the EVB
ground and power supply rails.
•
Ethernet signals routed to a National Semiconductor physical interface and Pulsejack RJ45 connector
with integrated magnetics.
•
MLB signals routed to SMSC MOST INIC with Tyco Optical Transceiver. INIC JTAG and MLB monitor
ports. Support for optional ROM INIC or MLB150 daughter card from SMSC.
•
4 active low LED’s and 4 pushbutton switches for development purposes.
•
Jumper selectable variable resistor connected to ADC channel 0, driving between VRH and VRL.
•
Liberal scattering of GND test points (surface mount loops) placed throughout the EVB.
Note – To alleviate confusion between jumpers and headers, all EVB jumpers are implemented as 2mm pitch
whereas headers are 0.1inch (2.54mm). This prevents inadvertently fitting a jumper to a header.
IMPORTANT
Before the EVB is used or power is applied, please fully read the following
sections on how to correctly configure the board.
Failure to correctly configure the board may cause irreparable component, MCU or EVB
damage.
