Errata for AT91FR40162
AT91FR40162
This Errata described below refers to:
1. Full Chip Erase Command May Not Fully Erase Flash
2. Concurrent Read Feature May Lead to Incorrect Flash Accesses
3. Sector Erase Command May Not Fully Erase the Sector
4. Flash Memory Uploader (FMU) Does Not Work at High Speed
5. Powering VPP Over VDDIO Might Lead to Partially Erased Sectors.
• The following datasheet:
• 121-lead BGA devices with the following references in the marking:
AT91FR40162-CI
58A03X
When using the Full Chip Erase Command to erase the Flash, the Flash may not be fully
erased. Some bytes may be different than 0xFF.
Workaround: Erase the Flash sector by sector with the Sector Erase command.
As the Flash is dual-plane, the Concurrent Read feature when programming or erasing is
implemented. Using that feature may lead to incorrect Flash accesses.
Workaround: Consider the Flash as single-plane and do not use Concurrent Read
feature when programming or erasing.
When using the Sector Erase Command to erase a sector, the Sector Erase operation
may not be successful if only few bytes are programmed in the sector.
If there are many programmed bits in the sector, Sector Erase operation is carried out
successfully.
Workaround: Before sending a Sector Erase Command, the corresponding sector
must be programmed with all bits to 0.
Because of lacking wait states, the ROMed FMU does not work at 66 MHz for the follow-
ing lot IDs: AK1216220, AK2030170, AK3120110, 3R1857, 3.2067, 3R2801, 3R2802,
3R3177, 3R3301, 3S4262, 3S3804 and 3S3805. The maximum frequency for these lots is
40 MHz.
Other lots contain a corrected FMU.
Workaround: None
When using the Sector Erase Command to erase a sector, the Sector Erase operation
may not be successful if VPP is higher than VDDIO.
