! Internal bi-directional reset controller with brown out detector
! External reset pushbutton
! USB powered. The dynamic power consumption on VDDCORE is less than 50 mA at
full speed when running out of the Flash. The total current drawn by all the I/O lines
cannot exceed 200 mA.
! External power can be applied via the 2.1 mm connector to the regulator in either
polarity because of the diode-rectifying circuit (CR3 to CR6). The minimum voltage
required is 7V. The board has a voltage regulator providing +3.3V. The regulator
allows the input voltage to be from 7V to 14V (REG1).
! The two power supplies are separated from each other by the diodes CR1 and CR2.
! On-chip embedded VDDCORE 1.8V regulator
! Two serial interface via RS-232 DB9 male sockets
– DBGU COM Port
– UART COM Port with RTS/CTS handshake control possibility (USART 0)
! USB V2.0 full-speed compliant, 12 Mbits per second (UDP)
! Four analog inputs (0V to 3.3V) via J7, J8, J9, J10 footprints
! Four pushbuttons via general PIO lines
! Four LEDs via high current PIO lines
! 20-pin JTAG/ICE interface connector
! DBGU COM port
One expansion connector (J5) gives access to all the microcontroller's signals.
All I/Os of the AT91SAM7S256 are routed to this connector. This allows the developer
to check the integrity of the components and to extend the features of the board by add-
ing external hardware components or boards.
This allows the developer to fit additional components for prototyping use.
