ATmega640/V-1280/V-1281/V-2560/V-2561/V [SUMMARY]

2549QS–AVR–02/2014

Problem Fix/Workaround

None.

2.

High current consumption in sleep mode

If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will

increase during sleep when executing the SLEEP instruction directly after a SEI instruction.

Problem Fix/Workaround

Before entering sleep, interrupts not used to wake the part from the sleep mode should be disabled.

11.5

ATmega1281 rev. B

• High current consumption in sleep mode

1.

High current consumption in sleep mode

If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will

increase during sleep when executing the SLEEP instruction directly after a SEI instruction.

Problem Fix/Workaround

Before entering sleep, interrupts not used to wake the part from the sleep mode should be disabled.

11.6

ATmega1281 rev. A

• Inaccurate ADC conversion in differential mode with 200× gain

• High current consumption in sleep mode

1.

Inaccurate ADC conversion in differential mode with 200× gain

With AVCC <3.6V, random conversions will be inaccurate. Typical absolute accuracy may reach 64 LSB.

Problem Fix/Workaround

None.

2.

High current consumption in sleep mode

If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will

increase during sleep when executing the SLEEP instruction directly after a SEI instruction.

Problem Fix/Workaround

Before entering sleep, interrupts not used to wake the part from the sleep mode should be disabled.

11.7

ATmega2560 rev. F

• ADC differential input amplification by 46dB (200x) not functional

1.

ADC differential input amplification by 46dB (200x) not functional

Problem Fix/Workaround

None.

11.8

ATmega2560 rev. E

No known errata.

11.9

ATmega2560 rev. D

Not sampled.
