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.

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

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