Migration from AL-D to AL-J (8Mbit-16Mbit)

The two devices S29AL008D and S29AL016D manufactured with the 200nm floating-gate technology are being migrated to the next-generation AL-J 110nm floating-gate technology.

All the hardware/software features and most of the package options of the old devices have been maintained to assure a seamless pin-to-pin compatible migration for the great majority of the applications.

In addition, the S29AL008J and S29AL016J devices offer improved access time (55ns) with the regulated voltage option and faster erase/program speed.

As additional security features, the new devices are offering an improved hardware boot sector protection via a dedicated hardware pin (WP#) and a 256byte secure region, which can be either provided with a random serial number and factory locked or programmable and lockable by the user. The AL-J series Flash has Sector Group Protection security features replacing the individual Sector Protection feature of the AL-D.
