• Manufacturer Part Number: mc68160b
• Description: Enhanced Ethernet Transceiver
• Manufacturer: Freescale Semiconductor, Inc

NOTES: 1. Although LOOP input is not ordinarily classifed as a controller pin, it is included in this table because its sense varies according to the controller used.
MOTOROLA ANALOG IC DEVICE DATA
2. The Motorola controller interface contained in the MC68360 (QUICC ) is compatible with the AMD 7990 (LANCE ) and 79C900 (ILACC ) controllers.
3. The pin sense is shown from the perspective of the identified controller pin.

mode. Additionally, in the standby mode, all of the controller inputs and outputs are
driven to the high impedance state. When the standby mode is deasserted, an internal
reset pulse of approximately 6.0 s duration is generated.
Following a period of operation in the standby mode, the time required to insure stable
data reception is approximately 100 ms.
