Table 35: Accordo5 - STA1295 - current consumption

provides an indication of power

consumption on each power supply rail for different use cases. All measurements are taken

on standard process samples, in typical conditions (midpoint of supply voltage range and

25°C junction temperature).

Cases 1 and 2 are relevant as low power consumption modes, typically operated on battery

supply.

Current consumption on VDD_IO_ON power rail is listed were relevant (which means in the

low power use cases, when battery operated). In the other use cases it can be considered

not relevant (< 0.1 mA).

A power consumption measurement campaign should be repeated by customer using their

actual application, that will surely differ from ST software demo applications in the way

software is implemented and optimized.

1. Values programmable through configurable PLL. Refer to SRC chapter for details.

2. The value of 600 MHz allows coupling with the maximum interconnect frequency of 200 MHz.

3. The value indicated as typical is the relevant one in some of the use cases where the IP itself can run up to

the frequency value indicated as maximum, but standard external components/cards cannot; typical setting

is recommended as a consequence.
