41.7 Rev. 8271E – 07/2012
41.8 Rev. 8271D – 05/11
1. Added ”DC Characteristics” on page 308. The following tables for DC characteristics - T
A
= -40C to 105C added:
Table 29-2 on page 309
Table 30-3 on page 324
Table 30-4 on page 325
Table 30-5 on page 325
2. Replaced the following typical characteristics by the plots that include les characteristics at “T
A
=-40C to 105C”:
”ATmega48PA Typical Characteristics” on page 352
”ATmega88PA Typical Characteristics” on page 401
”ATmega168PA Typical Characteristics” on page 451
”ATmega328P Typical Characteristics” on page 501
3. Removed the Power Save (Psave) maximum numbers for all devices throughout ”Electrical Characteristics – (TA =
-40°C to 85°C)” on page 308.
4. Changed the powerdown maximum numbers from 8.5 and 3µA to 10 and 5µA (ATmega48PA, ATmega88PA,
ATmega168PA and ATmega328P).
5. Changed the table note “Maximum values are characterized values and not test limits in production” to “Max values
are test limits in production throughout ”Electrical Characteristics – (TA = -40°C to 85°C)” on page 308.
1. Updated Figure 1-1 on page 12. Overlined “RESET” in 28 MLF top view and in 32 MLF top view.
2. Added EEAR9 bit to the ”EEARH and EEARL – The EEPROM Address Register” on page 31 and updated the all bit
descriptions accordingly.
3. Added a footnote “EEAR9 and EEAR8 are unused bits in ATmega48A/48PA and must always be written to zero” to
”EEARH and EEARL – The EEPROM Address Register” on page 31.
4. Updated Table 18-8 on page 164, “Waveform Generation Mode Bit Description” . WGM2, WGM1 and WGM0
changed to WGM22, WGM21 and WGM20 respectively.
5. Updated ”TCCR2B – Timer/Counter Control Register B” on page 165. bit 2 (CS22) and bit 3 (WGM22) changed
from R (read only) to R/W (read/write).
6. Updated the definition of fosc on page 181. fosc is the system clock frequency (not XTAL pin frequency)
7. Updated ”SPMCSR – Store Program Memory Control and Status Register” on page 270. Bit 0 renamed SPMEN
and added bit 5 “SIGRD”.
8. Replaced “SELFPRGEN” by “SPMEN” throughout the whole datasheet including in the “code examples”, except in
”Program And Data Memory Lock Bits” on page 289 and in ”Fuse Bits” on page 290.
9. Updated ”Register Summary” on page 621 to include the bits: SIGRD and SPMEN in the SMPCSR register.
10. Updated the Table 30-1 on page 322. Removed the footnote.
11. Updated the footnote of the Table 29-13 on page 315. Removed the footnote “Note 2”.
12. Updated ”Errata” on page 641. Added “Errata” TWI Data setup time can be too short.
1. Added Atmel QTouch Sensing Capability Feature
2. Updated ”Register Description” on page 100 with PINxn as R/W.
3. Added a footnote to the PINxn, page 100.
4. Updated “Ordering Information”,”ATmega328” on page 634. Added “ATmega328-MMH” and “ATmega328-MMHR”.
5. Updated “Ordering Information”,”ATmega328P” on page 635. Added “ATmega328P-MMH” and “ATmega328P-
MMHR”.
6. Added “Ordering Information” for ATmega48PA/88PA/168PA/328P @ 105C
7. Updated
”Errata ATmega328” on page 651 and ”Errata ATmega328P” on page 654
8. Updated the datasheet according to the Atmel new brand style guide.
