Hardware Configuration
Software Configuration
Hardware configurations are given for illustration only. The user should refer to the manufacturer
web site to check for memory device availability.
For Hardware implementation examples, please refer to ATSAM3S-EK schematics, which show
examples of a connection to an LCD module and NAND Flash.
Perform the following configuration:
In this example, the NAND Flash is not addressed as a “CE don’t care”. To address it as a “CE
don’t care”, connect NCS3 (if SMC_NFCS3 is set) to the NAND Flash CE.
• Assign the SMC_NFCSx (for example SMC_NFCS3) field in the CCFG_SMCNFCS Register
• Reserve A21 / A22 for ALE / CLE functions. Address and Command Latches are controlled
• NANDOE and NANDWE signals are multiplexed with PIO lines. Thus, the dedicated PIOs
• Configure a PIO line as an input to manage the Ready/Busy signal.
• Configure Static Memory Controller CS3 Setup, Pulse, Cycle and Mode according to NAND
