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.
