Mini Module Connector J1 – Peripheral Bus

Figure 2 displays the pin layout of the 56-pin Peripheral Bus Connector (J1) of the

eZ80F91 Mini Enet Module for eZ80AcclaimPlus!™. The eZ80F91 Mini Enet Module is

designed to connect to end-user applications via connectors J1 and J2, where the entire

system bus and I/O port signals are available. The module is also compatible with Zilog’s

eZ80F91 Modular Development System (eZ80F910200KITG). Table 1 lists the pins and

their functions.
