EEPROM Data Memory
ATtiny13A
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 64 bytes of internal data
SRAM in the ATtiny13A 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 ATtiny13A contains 64 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
