The above measurements are at typical process corner and room
temperature and do not account for process and temperature variations.
Peripheral operational current is measured with a 5 m cable with
maximum switching and BULK OUT transfers at 400 Mbps with 92.6%
bus utilization during one microframe. The actual average current in
customer applications will be lower.
MMC host operation current is measured with 8‐bit at 48 MHz writing
55AA pattern to an MMC 4.1 card at 15 Mbps throughput. The actual
average operational current will vary base on the data pattern and
throughput rates supported by the attached device.
ENVREG = 1 enables the internal voltage regulator.
