Page 9: Function Blocks
The SAM4E16 features an External Bus Interface (EBI) that permits interfacing to a broad range of external memories and virtually to any parallel peripheral. The SAM4E-EK board is equipped with one NAND Flash MT29F2G08ABAEA on the EBI. This can change to other type of flash by setting the Static Memory Controller. -

Conversely, it can be asserted low from the outside to reset the microcontroller Core and the peripherals. The NRST pin integrates a permanent pull-up resistor of 100kΩ to VDDIO. On the SAM4E-EK board, the NRST signal is connected to the LCD module and JTAG port. Note: At power-on, the NRST signal is asserted with default duration of two clock cycles. -
Page 11: Power Supply And Management
Power supply and management The Atmel SAM4E-EK board is supplied with an external 5V DC block through input J1. It is protected by a PolyZen diode (MN2) and an LC combinatory filter (MN3). The PolyZen is used in the event of an incorrect power supply connection. -
