41.7.1 All peripheral except USB
Default conditions, except where noted:
- Operating conditions
- VVDDIN = 3.3 V
- Oscillators
- XOSC (crystal oscillator) stopped
- XOSC32K (32 kHz crystal oscillator) running with external 32kHz crystal
- OSC8M at 8MHz
- Clocks
- OSC8M used as main clock source
- CPU, AHB and APBn clocks undivided
- The following AHB module clocks are running: NVMCTRL, HPB2 bridge, HPB1 bridge, HPB0
bridge
- All other AHB clocks stopped
- The following peripheral clocks running: PM, SYSCTRL
- All other peripheral clocks stopped
- I/Os are inactive with internal pull-up
- CPU in IDLE0 mode
- Cache enabled
- BOD33 disabled
In this default conditions, the power consumption Idefault is measured.
Operating mode for each peripheral in turn:
- Configure and enable the peripheral GCLK (When relevant, see conditions)
- Unmask the peripheral clock
- Enable the peripheral (when relevant)
- Set CPU in IDLE0 mode
- Measurement Iperiph
- Wake-up CPU via EIC (async: level detection, filtering disabled)
- Disable the peripheral (when relevant)
- Mask the peripheral clock
- Disable the peripheral GCLK (when relevant, see conditions)
Each peripheral power consumption provided in table x.y is the value (Iperiph - Idefault), using the same measurement method as for global power consumption measurement
Peripheral | Conditions | Typ. | Unit |
---|---|---|---|
RTC | fGCLK_RTC = 32kHz, 32bit counter mode | 7.4 | μA |
WDT | fGCLK_WDT = 32kHz, normal mode with EW | 5.5 | μA |
AC | Both fGCLK = 8MHz, Enable both COMP | 31.3 | μA |
TCx(1) | fGCLK = 8MHz, Enable + COUNTER in 8bit mode | 50 | μA |
TCC2 | fGCLK = 8MHz, Enable + COUNTER | 95.5 | μA |
TCC1 | fGCLK = 8MHz, Enable + COUNTER | 167.5 | μA |
TCC0 | fGCLK = 8MHz, Enable + COUNTER | 180.3 | μA |
SERCOMx.I2CM(2) | fGCLK = 8MHz, Enable | 69.7 | μA |
SERCOMx.I2CS | fGCLK = 8MHz, Enable | 29.2 | μA |
SERCOMx.SPI | fGCLK = 8MHz, Enable | 64.6 | μA |
SERCOMx.USART | fGCLK = 8MHz, Enable | 65.5 | μA |
I2S(3) | fGCLK_I2S_0 = 12.288MHz with source FDPLL with fFDPLL = 49.152MHz | 26.4 | μA |
DMAC(4) | RAM to RAM transfer | 399.5 | μA |
- All TCs from 4 to 7 share the same power consumption values.
- All SERCOMs from 0 to 5 share the same power consumption values.
- The value includes the power consumption of the FDPLL.
- The value includes the power consumption of the R/W access to the RAM.
