16 through 17.
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 V
or GND, depending on their inactive levels to reduce power consumption and
DD
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
general-purpose I/O pins support dual mode functions (SPI, Timer I/O, UARTs and bit I/O
with edge- or level-triggered interrupt functions on each pin). For more information on
eZ80F91 dual modes, refer to eZ80F91 Product Specification (PS0192)
.
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 eZ80F91 Product Specification
(PS0192).
Ethernet PHY and RJ45 Connector
The eZ80F92 Ethernet 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 eZ80F92 Ethernet 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) which is
multiplied by the phase-locked loop in the eZ80F91 MCU to create a 50 MHz system
clock

Memory
The eZ80F91 MCU contains 256 KB of internal Flash memory. Additional 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. Table 3 lists the status of the
jumper.

On-chip Flash memory boot block On-chip Flash
is write-protected.
There is 128 KB of fast SRAM on the eZ80F91 Mini Enet Module. 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 is 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 MCU 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.
Do not connect an RS232 interface without level shifters. There are
no RS232-level shifters on the eZ80F91 Mini Enet Module.
Note:
Physical Dimensions
The footprint of the eZ80F91 Mini Enet Module PCB is 2.00 " x 1.90 ". See Figure 4 for
dimensions and top-layer silkscreen.

Absolute Maximum Ratings
The stress 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).
