29. Errata
29.1 Chip Erase
29.1.1
Issue
In a certain percentage of units (date code 0809 and earlier), 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
29.1.3
Workaround
Resolution
Use Block Erase (opcode 50H) as an alternative. The Block Erase function is not affected by the
Chip Erase issue.
The Chip Erase feature is supported on devices with data code 0810 and later.
