EEPROM Data Memory
ATtiny261/ATtiny461/ATtiny861
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 ATtiny261/461/861 are all accessible through all these addressing modes.
The Register File is described in
Figure 6-2.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
Figure 6-3.
The ATtiny261/461/861 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 a detailed description of Serial data
downloading to the EEPROM, see
