8. Errata
The revision letter in this section refers to the revision of the ATtiny13 device.
8.1
ATtiny13 Rev. D
EEPROM can not be written below 1.9 Volt
1. EEPROM can not be written below 1.9 Volt
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.
8.2
ATtiny13 Rev. C
Revision C has not been sampled.
8.3
ATtiny13 Rev. B
Wrong values read after Erase Only operation
High Voltage Serial Programming Flash, EEPROM, Fuse and Lock Bits may fail
Device may lock for further programming
debugWIRE communication not blocked by lock-bits
Watchdog Timer Interrupt disabled
EEPROM can not be written below 1.9 Volt
8.3.1
Wrong values read after Erase Only operation
At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase Only oper-
ation may read as programmed (0x00).
Problem Fix/Workaround
If it is necessary to read an EEPROM location after Erase Only, use an Atomic Write opera-
tion with 0xFF as data in order to erase a location. In any case, the Write Only operation can
be used as intended. Thus no special considerations are needed as long as the erased loca-
tion is not read before it is programmed.
8.3.2
High Voltage Serial Programming Flash, EEPROM, Fuse and Lock Bits may fail
Writing to any of these locations and bits may in some occasions fail.
Problem Fix/Workaround
After a writing has been initiated, always observe the RDY/BSY signal. If the writing should
fail, rewrite until the RDY/BSY verifies a correct writing. This will be fixed in revision D.
8.3.3
Device may lock for further programming
Special combinations of fuse bits will lock the device for further programming effectively
turning it into an OTP device. The following combinations of settings/fuse bits will cause this
effect:
– 128 kHz internal oscillator (CKSEL[1..0] = 11), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled RSTDISBL = 0.
– 9.6 MHz internal oscillator (CKSEL[1..0] = 10), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled RSTDISBL = 0.
