1. Based on characterization, not tested in production.

2. I(5 V) = I(AVDD_5V_AFE) + I(AVDD_5V_PGA) + I(AVDD_5V_TXDRV).

I(DVDD_1V2)

1.2 V digital supply current RTE frequency = 48 MHz see(2)

I(DVDD_1V2)

1.2 V digital supply current RTE frequency = 120 MHz see(2)

1. Based on characterization, not tested in production.

2. The tests are performed with the following enabled digital blocks: 2 x GPT, 2 x SPI, 2 x USART, IPC, DMA, 2 x I2C, AES,

TRNG, QFS. Cortex™ frequency equals to 48 MHz and Cortex™ fetching by RAM. The value is calculated by measuring

the difference in the supply current with and without RTE enabled and running.
