Hardware
- NIC 50-RE and NIC 52-RE are pin compatible. You can take this from the following pages: Page 129 (NIC 50-RE), page 162 (NIC 52-RE)
Page 114: Do not place any electronic components in your design below the DIL32 socket! This may cause problems, especially if the NIC52-RE is used.
Page 122: Design your host system in such a way, that voltages up to 1.3 V at pins 29, 30 and 31 are logically interpreted as LOW. This must be assured by the design of your host system in order to avoid malfunction.
The cause for this behavior lies in the difference of the internal design of netX 50 and netX 52 (netX 50 has internal pull-down resistors, netX 52 has internal pull-up resistors) and in the necessity of additional pull-down resistors (10 kΩ) in NIC52-RE due to compatibility reasons
