29. Errata

29.1 Chip Erase

29.1.1

Issue

In a certain percentage of units, the Chip Erase feature may not function correctly and may

adversely affect device operation. Therefore, it is recommended that the Chip Erase commands

(opcodes C7H, 94H, 80H, and 9AH) not be used.

29.1.2

Workaround

Use Block Erase (opcode 50H) as an alternative. The Block Erase function is not affected by the

Chip Erase issue.

The Chip Erase feature may be fixed with a new revision of the device. Please contact Atmel for

the estimated availability of devices with the fix.
