The Atmel SAM4N Xplained Pro evaluation board contains a ATSAM4N16C microcontroller. The board itself is rather basic with only one user programmable LED and one user programmable push-button switch (the second switch is a reset switch). Pins of the microcontroller are available on headers on the board.
An on-board Embedded Debugger is included on the board, so that no external tools are required to program or debug the ATSAM4N16C.
The video below shows the evaluation board being unpacked.
Some features of the ATSAM4N16C microcontroller are:
- ARM Cortex-M4 that can run up to 100MHz
- 3 USARTs and 4 UARTS
- Real Time Clock (RTC) with calendar and alarm features
- 10 bit ADC and DAC
- 1Mb Flash memory
- 80kb SRAM
- The usual SPI, TWI, timers, PWM, etc.
The ATSAM4N16C does not contain any USB ports, Ethernet or external bus.
