This application note provides measurements of the current (ICC) consumed by the LAN91C111 as a

stand-alone device, as well as the measurement of the current consumed by the LAN91C111

Evaluation Board. This application note also details the procedures for measuring these currents.

The ICC current consumed by LAN91C111 as a stand-alone device includes all of the digital and

analog current consumed by both the MAC and PHY blocks inside the LAN91C111. Measuring this

current requires measuring the total current flowing into all of the Vdd and Avdd pins of the

LAN91C111. This current does not include the current consumed by the termination resistors for the

Ethernet transmit and receive circuits.

The current consumed by the LAN91C111 Evaluation Board includes the current consumed by the

LAN91C111 as a stand-alone device plus the supply current consumed by the passive components

used in the analog front end. These passive components consist of magnetics, resistors on the

Ethernet transmit circuit.

Current consumption of the LAN91C111 varies according to which state it is in. These states include

the idle state, three power-down states and normal operation.

For the LAN91C111 TQFP package, the Vdd and AVdd pins are located as follows: Pin #1, #11, #16,

#33, #44, #62, #77, #98, #110, #120.

For the LAN91C111 QFP package, the Vdd and AVdd pins are located as follows: Pin #3, #13, #18,

#35, #46, #64, #79, #100, #112, #122.

All of the measurements made for this application note were made using the TQFP package.
