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(R) 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 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, please refer to the 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 the EZ80F91 Product Specification (PS0192).
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 10Mbps, which works in either a 100 Mbps or a 10 Mbps network. Software can also configure the PHY for 100Mbps 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.

5MHz Clock
The EZ80F91 Mini Enet Module contains a 5MHz crystal oscillator (Y2) that is multiplied by the phase-locked loop in the EZ80F91 MCU to create a 50MHz system clock
Memory
The EZ80F91 MCU contains 256KB 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.

In (Default) On-chip Flash is enabled for writing to boot block. Out
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 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 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. Note: Do not connect an RS-232 interface without level shifters. There are no RS232-level shifters on the EZ80F91 Mini Enet Module.
Physical Dimensions
The footprint of the EZ80F91 Mini Enet Module PCB is 2.00 inches by 1.90 inches. See Figure 4 for dimensions and top-layer silkscreen.

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).
