4.3.1

Processor

The Atmel SAM4E-EK is equipped with a SAM4E16 device in BGA144 package.
4.3.2

Memory

The SAM4E16 chip embeds:
•
1024kB of embedded Flash
•
128kB of embedded SRAM
•
16kB of ROM with embedded boot loader routines (UART, USB) and In-Application Programming functions
(IAP) routines
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.

NCS0 chip select signal is used for NAND Flash chip selection. Furthermore, a dedicated jumper can disconnect it from
the on-board memories, thereby letting NCS0 free for other custom purposes.
