4 SmartFusion Programming

SmartFusion cSoCs have three separate flash areas that can be programmed:

1. The FPGA fabric
2. The embedded nonvolatile memories (eNVMs)
3. The embedded flash ROM (eFROM)

There are essentially three methodologies for programming these areas:

1. In-system programming (ISP)
2. In-application programming (IAP)
   • FPGA fabric, eNVM, and eFROM
3. Pre-programming (non-ISP)

Programming, whether ISP or IAP methodologies are employed, can be done in two ways:

1. Securely using the on chip AES decryption logic
2. In plain text
