This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
Figure 10. On-chip Data SRAM Access Cycles
The ATmega162 contains 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.
