High-Voltage Serial Programming Algorithm
Table 17-10. Pin Name Mapping
The minimum period for the Serial Clock Input (SCI) during High-voltage Serial Programming is
220 ns.
Table 17-11. Pin Values Used to Enter Programming Mode
To program and verify the ATtiny13 in the High-voltage Serial Programming mode, the following
sequence is recommended (See instruction formats in
The following algorithm puts the device in High-voltage Serial Programming mode:
If the rise time of the Vcc is unable to fulfill the requirements listed above, the following alterna-
tive algorithm can be used.

1. Set Prog_enable pins listed in
2. Apply 4.5 - 5.5V between VCC and GND. Ensure that Vcc reaches at least 1.8V within
3. Wait 20 - 60µs, and apply 11.5 - 12.5V to RESET.
4. Keep the Prog_enable pins unchanged for at least 10µs after the High-voltage has
5. Release the Prog_enable[2] pin to avoid drive contention on the Prog_enable[2]/SDO
6. Wait at least 300µs before giving any serial instructions on SDI/SII.
7. Exit Programming mode by power the device down or by bringing RESET pin to 0V.
1. Set Prog_enable pins listed in
2. Apply 4.5 - 5.5V between VCC and GND.
3. Monitor Vcc, and as soon as Vcc reaches 0.9 - 1.1V, apply 11.5 - 12.5V to RESET.
