3.
Removed the Power Save (Psave) maximum numbers for all devices throughout ”Electrical Characteristics – (TA =
-40°C to 85°C)” on page 301.
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 301.
1. Updated Figure 1-1 on page 3. 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 22 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 22.
4.
Updated Table 18-8 on page 156, “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 157. 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 173. fosc is the system clock frequency (not XTAL pin frequency)
7.
Updated ”SPMCSR – Store Program Memory Control and Status Register” on page 263. 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 282 and in ”Fuse Bits” on page 283.
9. Updated ”Register Summary” on page 9 to include the bits: SIGRD and SPMEN in the SMPCSR register.
10. Updated the Table 29-1 on page 301. Removed the footnote.
11. Updated the footnote of the Table 29-18 on page 312. Removed the footnote “Note 2”.
12. Updated ”Errata” on page 29. Added “Errata” TWI Data setup time can be too short.
1. Added Atmel QTouch Sensing Capability Feature
2. Updated ”Register Description” on page 92 with PINxn as R/W.
3. Added a footnote to the PINxn, page 92.
4. Updated “Ordering Information”,”ATmega328” on page 22. Added “ATmega328-MMH” and “ATmega328-MMHR”.
5.
Updated “Ordering Information”,”ATmega328P” on page 23. Added “ATmega328P-MMH” and “ATmega328P-
MMHR”.
6. Added “Ordering Information” for ATmega48PA/88PA/168PA/328P @ 105C
7. Updated ”Errata ATmega328” on page 33 and ”Errata ATmega328P” on page 34
8. Updated the datasheet according to the Atmel new brand style guide.
1. Added 32UFBGA Pinout, Table 1-1 on page 3.
2. Updated the “SRAM Data Memory”, Figure 8-3 on page 19.
3. Updated ”Ordering Information” on page 16 with CCU and CCUR code related to “32CC1” Package drawing.
4. “32CC1” Package drawing added ”Packaging Information” on page 24.
