Increased AC offset on low input voltages
Analog comparator may have an offset greater than 40 mV on low input
voltages (Vin < 0.5V) when VCC > 3.6V.
Fix/Workaround:
Avoid using low input voltages to the analog comparator when VCC is
greater than 3.6V
38.2 Errata ATmega88PA
The revision letter in this section refers to the revision of the ATmega88PA device.
38.2.1 Rev. F
1 –
Analog MUX can be turned off when setting ACME bit
If the ACME (Analog Comparator Multiplexer Enabled) bit in ADCSRB is set
while MUX3 in ADMUX is '1' (ADMUX[3:0]=1xxx), all MUXes are turned off
until the ACME bit is cleared.
Fix/Workaround:
Clear the MUX3 bit before setting the ACME bit.
2 –
TWI data setup time can be too short
When running the device as a TWI slave with a system clock above 2 MHz,
the data setup time for the first bit after ACK may in some cases be too
short. This may cause a false start or stop condition on the TWI line.
Fix/Workaround:
Insert a delay between setting TWDR and TWCR.
3 –
Increased AC offset on low input voltages
Analog comparator may have an offset greater than 40 mV on low input
voltages (Vin < 0.5V) when VCC > 3.6V.
Fix/Workaround:
Avoid using low input voltages to the analog comparator when VCC is
greater than 3.6V
38.2.2 Rev. B to E
Not sampled.
38.2.3 Rev. A
1 –
Power consumption in power save modes
Power consumption in power save modes will be higher due to improper
control of internal power management.
Fix/Workaround:
This problem will be corrected in Rev B.
2 –
Start-up time for the device
Due to implementation of a different NVM structure, the startup sequence for
the device will require longer start-up time.
