The SAM4SD32 features an External Bus Interface (EBI) that permits interfacing to a broad range of
external memories and virtually to any parallel peripheral. The SAM4S-EK2 board is equipped with a
memory device connected to the SAM4 EBI:
Figure 4-2.
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.
The clock generator of a SAM4SD32 microcontroller is composed of:
The SAM4S-EK2 board is equipped with one 12 MHz crystal, optional Piezoelectric Ceramic Resonator
12 MHz (Murata ref. CSTCE12M0G15L99-R0), one 32.768 Hz crystal and an external clock input con-
nector (optional, not populated by default).

One NAND Flash MT29F2G08ABAEA.
A Low Power 32.768 Hz Slow Clock Oscillator with bypass mode
A 3 to 20 MHz Crystal Oscillator, which can be bypassed (12 MHz needed in case of USB)
A factory programmed fast internal RC Oscillator. 3 output frequencies can be selected: 4 (default
value), 8 or 12 MHz.
A 60 to 130 MHz PLL (PLLB) providing a clock for the USB Full Speed Controller
A 60 to 130 MHz programmable PLL (PLLA), capable to provide the clock MCK to the processor and
to the peripherals. The input frequency of PLLA is from 7.5 to 20 MHz
