5 / 34 page 5 2586N-Appendix B–AVR–08/11 ATtiny25 2.4 Brown-Out Detection Note: 1. VBOT may be below nominal minimum operating voltage for some devices. For devices where this is the case, the device is tested down to V CC = VBOT during the production test. This guar- antees that a Brown-out Reset will occur before VCC drops to a voltage where correct operation of the microcontroller is no longer guaranteed. 2.5 Serial Programming Characteristics Note: 1. 2 t CLCL for fck < 12 MHz, 3 tCLCL for fck >= 12 MHz Table 2-4.
