Errata

27.1

Chip Erase

27.1.1 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.

27.1.2 Workaround

Use block erase (opcode 50H) as an alternative. The block erase function is not affected by the chip erase issue.

27.1.3 Resolution

The chip erase feature may be fixed with a new revision of the device. Please contact Adesto for the estimated availability of

devices with the fix.
