1. Valid only if programmed using a programming tool that is qualified
2. Circuits can be programmed more than 10 times but in that case, the retention time is no longer
guaranteed.
2.3 Current consumption
The tables below give the current consumption for the circuit in different configurations. The figures are indicative
only and may change as a function of the actual software implemented in the circuit.
Table 2-5 gives the current consumption for the flash version of the circuit. The peripherals are disabled. The
parallel ports are configured in input with pull up. Their pins are not connected externally.
