Notes
1. For the sake of simplicity in describing the interface, Power and Ground nets are omitted
from this table. The entire interface is represented in the eZ80F91 Mini Enet Module
schematics (see Figure 5 on page 14 and Figure 6 on page 15).
2. Additional note: external capacitive loads on RD, WR, IORQ, MREQ, D0–D7 and A0–A23
should be below 10 pF to satisfy the timing requirements for the eZ80® CPU. All unused
inputs should be pulled to either VDD or GND, depending on their inactive levels to
reduce power consumption and to reduce noise sensitivity. To prevent EMI, the EZ80CLK
output can be deactivated via software in the eZ80F91’s Peripheral Power-Down
Register.

Onboard Component Description
I/O Connector
The I/O connector features 32 general-purpose 3.3 V CMOS I/O pins that can be used as
outputs or inputs interfacing to external logic. All I/Os are 5 V tolerant. Some of the GPIO
pins support dual mode functions (SPI, Timer I/O, UARTs, and bit I/O with edge- or leveltriggered interrupt functions on each pin). For more information on eZ80F91 dual modes,
refer to eZ80AcclaimPlus! Connectivity ASSP eZ80F91 ASSP Product Specification
(PS0270).
Peripheral Bus Connector
The peripheral bus connector features 24 pins that provide access to the eZ80F91 Mini
Enet Module address bus and 8 pins that provide access to the module data bus. For more
information on eZ80F91 address and data buses, refer to eZ80AcclaimPlus! Connectivity
ASSP eZ80F91 ASSP Product Specification (PS0270).
Ethernet PHY and RJ45 Connector
The eZ80F91 Mini Enet Module contains a Micrel KS8721BL 10/100 Ethernet PHY with
Media Independent Interface (MII) and a HALO RJ45 with integrated magnetics and two
LEDs (transformer and common-mode chokes).
The eZ80F91 Mini Enet Module defaults to 10 Mbps, which works in either a 100 Mbps
or a 10 Mbps network. Software can also configure the PHY for 100 Mbps or autosense.
Ethernet LEDs
The Ethernet connection is provided by the HALO RJ45 connector. It contains two green
LEDs that are located next to each other on the eZ80F91 Mini Enet Module. When PHY is
receiving data, the left LED is ON. When the PHY is transmitting data, the right LED is
ON.
5 MHz Clock
The eZ80F91 Mini Enet Module contains a 5 MHz crystal oscillator (Y2) that is multiplied by the phase-locked loop (PLL) in the eZ80F91 ASSP to create a 50 MHz system
clock

Memory
The eZ80F91 ASSP contains 256 KB of internal Flash memory. Additional user memory
can be accommodated via the system bus on connectors J1 and J2. To program the on-chip
Flash memory, install jumper JP1 on the mini module (see Table 3).

There is 128 KB of fast SRAM on the eZ80F91 Mini Enet Module for eZ80AcclaimPlus!.
Access time is 12 ns, which requires one wait-state access. The eZ80F91 on-chip SRAM
can be used with zero wait states.
IrDA Transceiver
The eZ80F91 Mini Enet Module is shipped without an IrDA transceiver installed.
If you install an on-board transceiver, such as the Zilog ZHX1810, it is connected to PD0
(TX), PD1 (RX), and PD2 (Shutdown, IR_SD). The IrDA transceiver is of the LED type
870 nm Class 1.
The IrDA transceiver is accessible via the IrDA controller attached to UART0 on the
eZ80F91 device.
To use the UART0 for console or to save power, the transceiver can be disabled by the
software or by an off-board signal when using the proper jumper selection. The transceiver
is disabled by setting PD2 (IR_SD) High or by pulling the DIS_IRDA pin on the I/O connector Low. The shutdown is used for power savings. To enable the IrDA transceiver,
DIS_IRDA is left floating and PD2 is set to Low.
Serial Interface Ports
The eZ80F91 ASSP contains two UARTs with programmable baud rate generators.
UART0 is connected to GPIO PD[0:7] on the I/O connector. UART1 is connected to
GPIO PC[0:7] on the I/O connector.

Absolute Maximum Ratings
Stresses greater than those listed in Table 4 can cause permanent damage to the device.
These ratings are stress ratings only. Operation of the device at any condition outside those
indicated in the operational sections of these specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
For improved reliability, unused inputs should be tied to one of the supply voltages (VDD
or VSS).
