Chip Erase
Issue
Workaround
Resolution
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 60h and C7h) not be used.
Use the Block Erase (4KB, 32KB, or 64KB) commands as an alternative. The Block Erase func-
tion is not affected by the Chip Erase issue.
The Chip Erase feature is being fixed with a new revision of the device. Please contact Atmel for
the estimated availability of devices with the fix.
