Notes
(1) Typical condition for playback of MP3 music with 44.1 KHz / 128 kbit with 32Ω headphones. The
internal charge pump generates VDD_CORE. No external SDRAM connected. USB2.0 in standby.
(2) Maximum condition for ARM running at 250 MHz, AHB/APB bus and memory at 64 MHz, USB 2.0 in HS
operation. For high current mode, the charge pump is disabled and IDD_CORE_OP is added to the total
current consumption at BVDD.
(3) For maximum value: assuming maximum output power of 2x40 mW sine-wave into headphones (16Ω).
Internal loss of headphone AB amplifier is included.
In the case of standby mode or in the case of configuring the device to stopped clock, following current consumption is measured.
