17. Errata

17.1

Chip Erase

17.1.1

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 60h and C7h) not be used.

17.1.2

Workaround

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.

17.1.3

Resolution

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.
