Other Parts Discussed in Thread: RM57L843, HALCOGEN

I have following qeustion for RM57L843 :

1) When production version of RM57L843 will be available?

2) According to datasheet following MII signals available but HDK schematic regards them as NC.

Can I use these MII signals for connecting PHY?

If yes, how can I configure them using HALCOGEN? (HALCOGEN doesn't provide enough information)

The production release for RM57L843 is scheduled for end of September.

Did you select MII on the PinMux tab in HALCoGen?

Dear Bob,

I appreciate your kind reply in advance.

According to RM57L843 datasheet pinout section,

there might be dedicated MII pins which are not need to be muxed with other signals.

One example is pin U8 as MII_TXD[0], this pin was NC on older familiy products.

But U8 is not shown on HALCOGEN Pin muxing section as captured below.

I'd like to use dedicated MII signals to keep pin confliction as low as possible.

Best Regards,

Kooyong

Yes, on the RM57L843 there are dedicated signals for MII. If you use the dedicated signals, then you do not check the MII Pin Muxing block shown above. No muxing is required when using the dedicated signals.

Hello Bob,

Thanks for your confirmation.
It will help a lot to my new design!!!

Hello Bob,

Could you provide whole pinmap(with pinmux info) excel table for RM57L843?

Best Regards,

I don't have that in an Excel table. The information is in the datasheet.
