Ethernet and MII Management
This section provides the AC and DC electrical characteristics for Ethernet and MII management.
8.1
Ethernet Controller (10/100 Mbps)—MII/RMII Electrical
Characteristics
The electrical characteristics specified here apply to all MII (media independent interface) and RMII
(reduced media independent interface), except MDIO (management data input/output) and MDC
(management data clock). The MII and RMII are defined for 3.3 V. The electrical characteristics for MDIO
and MDC are specified in Section 8.3, “Ethernet Management Interface Electrical Characteristics.”
8.1.1
DC Electrical Characteristics
All MII and RMII drivers and receivers comply with the DC parametric attributes specified in Table 22.
The potential applied to the input of a MII or RMII receiver may exceed the potential of the receiver’s
power supply (that is, a MII driver powered from a 3.6-V supply driving VOH into a MII receiver powered
from a 2.5-V supply). Tolerance for dissimilar MII driver and receiver supply potentials is implicit in these
specifications.

Notes:
1. Actual attainable baud rate will be limited by the latency of interrupt processing.
2. The middle of a start bit is detected as the 8th sampled 0 after the 1-to-0 transition of the start bit. Subsequent bit values are
sampled each 16th sample.
