ATtiny11/12
High-voltage Serial
Programming

ATtiny11/12
provides a convenient way to download program and data into the ATtiny12 inside the
user’s system.
The program and data memory arrays in the ATtiny12 are programmed byte-by-byte in
either programming mode. For the EEPROM, an auto-erase cycle is provided within the
self-timed write instruction in the Low-voltage Serial Programming mode.
During programming, the supply voltage must be in accordance with Table 22.
Table 22. Supply Voltage during Programming
This section describes how to program and verify Flash Program memory, EEPROM
Data memory (ATtiny12), lock bits and fuse bits in the ATtiny11/12.
