TMS320F28379D: EMIF LAN9252

Part Number: TMS320F28379D

Hi Team,

Here're some issues from the customer may need your help:

1. What mode can be configured to communicate with the HBI of LAN9252?

2. LAN9253 supports 16-bit data address line multiplexing. Which control signal is used to control it in TMS320F28379D?

3. The 8bit data address lines are separated, how to connect the high bits of DSC? Floating?

Thanks & Regards

Yale

    Yale,

                I am not familiar with LAN9252. I downloaded the datasheet and took a look. It doesn’t appear interfacing with EMIF is possible. Customer may be better off interfacing through SPI or GPIO port.

    There is no Address Latch Enable (ALE) signal in 28379. EMIF does not support multiplexed address/data bus.
