FTP and RAM memory mapping

The LDLL16EN is equipped with a 2-kbit EEPROM, used also to store device configuration data. Part of this

memory shall be managed by the customer.

The device can operate in standalone mode (no microcontroller used) thanks to full configurability by few time

programmable (FTPs) memory registers. In application, the FTPs can be programmed (up to NFTP cycles) via the

CAN FD light compatible interface, even if the device does not integrate any counter taking note about the FTP

writing cycles. By the way, for safety reason, any FTP sector can be locked to avoid unintentional writing.

The user can program FTPs setting the CS pin to "1" via HW or via SW.
