EEPROM Data Memory
Data Memory Access Times
Figure 5-3.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
Figure 5-4.
The ATmega48/88/168 contains 256/512/512 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.
