According the the MPC5744P data sheet,
I could find the many pin maps of Ethernet feature on LQFP144.
However orderable part table describes that eithernet is available only for 257 MAPBGA.
Why pin maps related to Ethernet is available for LQFP144?
Is there any way to utilize Ethernet on LQFP144?
The pin numbers for LQFP144 are described as follows:
Ethernet Transmit Error: 80
Ethernet MII/RMII Receive data 1: 33
Ethernet MII/RMII Receive data 0: 34
Ethernet Receive valid data: 37
Ethernet Receive clock: 32
Ethernet MII Transmit data: 76
Ethernet Timer output: 121
Ethernet MDIO Clock output: 133
Ethernet Timer output2: 139
Ethernet Transmit data valid: 85
Ethernet RMII clock/Transmit clock: 81
Ethernet MII/RMII Transmit data 0: 79
Ethernet MII/RMII Transmit data 1: 77
Ethernet MII/RMII Transmit data 3: 75
Ethernet MII Carrier sense: NA (only for MAPBGA: F4)
Ethernet MII Collision: NA (only for MAPBGA: F3)
....
Dear Peter,
Thank you for your clarificatoin.
By the way, could you recommend me an MPC5xxx LQFP device (other than MPC5744P) which supports ethernet?
Best regards,
Jaecheol Lee
Hi,
This really depends on target application.
I can recommend you MPC574xG/C family which is targeted for communication.
Peter
Hello,
If you require Ethernet then you must order 257 MAPBGA. Otherwise no all pins are available.
