! 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
! External power can be applied via the 2.1 mm connector to the regulator in either
! 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
! 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.
full speed when running out of the Flash. The total current drawn by all the I/O lines
cannot exceed 200 mA.
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).
– DBGU COM Port
– UART COM Port with RTS/CTS handshake control possibility (USART 0)
