EEPROM Data Memory
ATtiny25/45/85
Data Memory Access Times
When using register indirect addressing modes with automatic pre-decrement and post-incre-
ment, the address registers X, Y, and Z are decremented or incremented.
The 32 general purpose working registers, 64 I/O Registers, and the 128/256/512 bytes of inter-
nal data SRAM in the ATtiny25/45/85 are all accessible through all these addressing modes.
The Register File is described in
Figure 5-2.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
Figure 5-3.
The ATtiny25/45/85 contains 128/256/512 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. For details see
155.
