Erase Suspend
AC Characteristics – Maximum Clock Frequencies for Read Operations
Issue: Parts may not program correctly if a device is in the Erase Suspend state.
Workaround: None. It is recommended to not use the Byte/Page Program commands (opcodes
02h and A2h) during an Erase Suspend state. Systems should resume from Erase Suspend first
before attempting to program a device.
Resolution: The Erase Suspend feature is being fixed with a new revision of the device. Please
contact Atmel for the estimated availability of devices with the fix.
Issue: Devices currently do not meet the maximum specified clock frequency for the following
read operations: Read Array, Read Sector Protection Registers, Read Sector Lockdown Regis-
ters, Read OTP Security Register, Read Status Register, and Read Manufacturer and Device
ID. Reading at clock frequencies higher than those listed below could cause read errors.
Workaround: None. Devices are limited to the clock frequencies specified above.
Resolution: The clock frequency issues are being fixed with a new revision of the device.
