EEPROM Read/Write Access
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
Figure 7-4.
The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P contains 256/512/512/1K bytes of
data EEPROM memory. It is organized as a separate data space, in which single bytes can be
read and written. The EEPROM has an endurance of at least 100,000 write/erase cycles. The
access between the EEPROM and the CPU is described in the following, specifying the
EEPROM Address Registers, the EEPROM Data Register, and the EEPROM Control Register.
”Memory Programming” on page 296
in SPI or Parallel Programming mode.
The EEPROM Access Registers are accessible in the I/O space.
The write access time for the EEPROM is given in
lets the user software detect when the next byte can be written. If the user code contains instruc-
tions that write the EEPROM, some precautions must be taken. In heavily filtered power
supplies, V
period of time to run at a voltage lower than specified as minimum for the clock frequency used.

situations.
In order to prevent unintentional EEPROM writes, a specific write procedure must be followed.
Refer to the description of the EEPROM Control Register for details on this.
When the EEPROM is read, the CPU is halted for four clock cycles before the next instruction is
executed. When the EEPROM is written, the CPU is halted for two clock cycles before the next
instruction is executed.
