Errata

ATtiny2313 Rev C

No known errata.

ATtiny2313 Rev B

• Wrong values read after Erase Only operation: At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase Only operation may read as programmed (0x00).Problem Fix/Workaround: Use an Atomic Write operation with 0xFF as data to erase a location. The Write Only operation can be used as intended.
• Parallel Programming does not work: Parallel Programming is not functioning correctly.Problem Fix/Workaround: Serial Programming is still working correctly. Avoid disabling In-System Programming (SPIEN) and Reset (RSTDISBL) to allow reprogramming.
• Watchdog Timer Interrupt disabled: If the watchdog timer interrupt flag is not cleared before a new timeout occurs, the watchdog will be disabled.Problem Fix/Workaround: Ensure there is enough time to service the first timeout event before a new watchdog timeout occurs.
• EEPROM can not be written below 1.9 volts: Writing the EEPROM at VCC below 1.9 volts might fail.Problem Fix/Workaround: Do not write the EEPROM when VCC is below 1.9 volts.
