Input
A Low enables a Write to on-chip Flash
memory. If this pin is unconnected, on-chip
Flash memory is write-protected; not used
with the eZ80190 Module.
Notes: *External capacitive loads on RD, WR, IORQ, MREQ, D0–D7 and A0–A23 should be below 10 pF to satisfy
timing requirements for the 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 eZ80190 Peripheral Power-Down
Register.
All inputs are CMOS level 3.3 V (5 V tolerant), except where otherwise noted.

Onboard Component Description
Logic-Level I/Os
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, I2C,
UARTs, and bit I/O with edge- or level-triggered interrupt functions on each pin).
For more information on eZ80190 dual modes, please refer to the eZ80190 Product Specification (PS0066).
Onboard Battery Backup
An onboard 0.1 F capacitor (GoldCap) is used to bridge power outages of 2–4
hours if the power supply to the module is disconnected. The capacitor is charged
to 3.1 V during normal operation and is discharged through the on-chip Real Time
Clock. The VRTC pin is available on the I/O connector of the module to connect
external components to a power supply or to a larger GoldCap.
Caution: Do not connect a Lithium Battery to the GoldCap capacitor, because
onboard charging circuitry for the capacitor can destroy the lithium
battery.
Ethernet Media Access Controller
The eZ80190 contains a CS8900A EMAC which is attached to the data/address
bus of the processor. This chip is connected to the processor’s CS3 Chip Select,
A0–A3, D0–D7, RD, WR, and PD4 pins for interrupt purposes. Connection of pins
PD6 and PD7 for LANACT (wake-up from sleep) and SLEEP is optional and resistor-selectable onboard.
Ethernet LEDs
There are two green LEDs, a Link LED and a LAN LED, that are located adjacent
to each other on the eZ80190 Module. A steady LAN LED (top) indicates received
link pulses from the Ethernet. A flashing Link LED (bottom) indicates Traffic (RX or
TX) on the LAN.

An RJ45 loopback connector can be used to verify the correct operation of the
Receiver and the Transmitter. The green LED should be on if RX+ is connected
with TX+ and RX– is connected with TX–.
Ethernet Connector
The eZ80190 is equipped with an RJ45 connector that features integrated magnetics (transformer, common mode chokes). The remaining pins on the onboard
RJ45 connector are not connected.
Node assignments for the RJ45 Ethernet connector are shown in Table 3.

Node assignment, in contrast to hub assignment, means that a straight-through
cable (equivalent pin numbers on both sides of the cable are connected to each
other) is used to attach the board to an Ethernet hub or switch. To connect the
eZ80190 Module directly to another node (e.g., a personal computer), a crossover
cable must be used.
The EMAC can be additionally protected by placing a U9 ESD protection array on
the module. This array can be either of the LCDA15C-6 (Semtech) or ESDA25B1
(ST Microelectronics) devices.
GPIO Pins for Enabling LAN Activity, Sleep, Interrupt
GPIO input bit PD4 serves as an active High interrupt input for the EMAC’s
INTRQ0 output.
GPIO output bit PD7 can be used to place the EMAC into SLEEP mode. In
SLEEP mode, the CS8900 draws less current, because only the receiver is operating. A zero-Ohm resistor at position R14 on the eZ80190 is required for this
function. In this case, the PD6 pin is not available for GPIO on the I/O connector.
If LAN activity is detected, the LANACT signal is pulled Low. The LANACT is connected to GPIO input PD6 and can be used in interrupt edge-detection mode to
wake up and reinitialize the Ethernet chip. A zero-Ohm resistor at position R15 on

the module is required for this function. In this case, the PD6 pin is not available
for GPIO on the I/O connector.
EMAC Ports
The I/O base address is user-selectable. The EMAC is connected as an 8-bit
device.
EMAC Access
For 50MHz operation, set CS3_CTL (I/O address 0xB3) to 0xF8 (7 wait states for
I/O). CS3 is used for selecting the Ethernet MAC. By pulling JP1 pin 25 (DIS_Eth)
Low, access to the Ethernet MAC can be disabled on a per-cycle basis.
Memory
The eZ80190 offers SRAM and Flash memories and the wait states that support
memory operations, as described in this section.
Wait States
To ensure that valid data is read from or written to slower memories, a number of
wait states must be inserted into the memory or I/O access operations by the processor. The number of wait states that are required should be added by programming the chip select control registers. To calculate the minimum number of wait
states required, refer to Table 4.

Static RAM
The eZ80190 features 512 KB of fast SRAM. Access speed is typically 12 ns or
faster, allowing zero-wait-state operation at 50 MHz. With the CPU at 50 MHz,
PS019101-1003
PRELIMINARY

eZ801905050MOD
eZ80190 Module Product Specification
15
onboard SRAM can be accessed with zero wait states. The CS1_CTL register can
be set to 08h (no wait states).
Flash Memory
The Flash Boot Loader, application code, and user configuration data are held
permanently in NOR Flash memory. A typical application requires eight times
more ROM for code than RAM. As an example, for 128 KB onboard SRAM, 1 MB
of ROM is required. The eZ80190 allows NOR Flash memories between
4 megabits (512 KB) and 32 megabits (4 MB) to be used. The chips are housed in
wide TSOP40 cases. Typical Flash ROM access time is 100 ns.
For 50 MHz CPU operation, set the Chip Select Control register CS0_CTL (I/O
address 0xAA) to 0xA8. This setting selects 5 wait states. CS0 is used for selecting Flash memory. By pulling JP1 pin 26 (DIS_Flash) Low, access to Flash memory can be disabled on a per-cycle basis.
Real-Time Clock
An onboard real-time-clock operates continually, even if the system power supply
is down. An onboard capacitor (GoldCap) or external accumulator/battery serves
as a standby power supply. The Real-Time-Clock M41T11 contains Binary Coded
Decimal (BCD) counting registers for Seconds, Minutes, Hours, Day, Month, and
Year; a Century bit and 56 bytes of backed-up RAM are also included. The fully
charged 0.1 F GoldCap bridges power outages with a maximum of 4 hours. The
GoldCap, in contrast to a battery or an accumulator, offers the dual advantage of
no service (replacement) requirements and no effects upon memory.
The I2C addresses of the RTC are 0xD0 for WRITE and 0xD1 for READ. The I2C
sequence for writing to the RTC is:
Start → 0xD0 → RegNo → VALUE1 → … → VALUEn → Stop
and the sequence for reading from the RTC is:
Start → 0xD1 → RegNo → VALUE1 → … → VALUEn → Stop
where VALUE1…VALUEn… are sent by the RTC. The processor (I2C Master)
requests another value by sending an ACK. The first register to be read is set by a
preceding WRITE sequence, without sending data values. Clock updates do not
occur while any of the seven clock registers are being read. See Figure 5.

Reset Generator
The onboard Reset Generator Chip performs reliable Power-On Reset. The chip
generates a reset pulse with a duration of 200 ms if the power supply drops below
2.93 V. This reset pulse ensures that the board always starts in a defined condition. The RESET pin on the I/O connector reflects the status of the RESET line. It
is a bidirectional pin for resetting external peripheral components or for resetting
the eZ80190 with a low-impedance output (e.g. a 100-Ohm pushbutton).
Serial Interface Ports
The processor contains two 16550-style UARTs with programmable baud rate
generators. When the eZ80190 Module is plugged in to the eZ80® Development
Platform, UART0 is connected to a console connector and UART1 is connected to
a modem connector. There are no RS232-level shifters on the eZ80190.
Note: Do not connect an RS-232 interface without level shifters.

ESD/EMI Protection
Caution: The eZ80190 is a component that is intended to be part of a system
design for end-user devices. Therefore, the user must exercise caution
to use ESD protection on the I/O pins.
The EMAC can be additionally protected by placing an ESD protection array on
the eZ80190 at position U9. Either use ESDA25B1 from ST Microelectronics or
LCDA15C-6 from Semtech. A mounting hole on the board can be used for
grounding the shield of the Ethernet RJ45 jack to prevent surge or ESD currents
from flowing through the digital circuitry.
The RJ45 Ethernet Connector on the eZ80190 contains a transformer and common mode chokes for EMI suppression.
Caution: CMOS I/Os are ESD-sensitive and must be handled with care.
Handling of the module should be performed in ESD-safe
environments (for example with a wrist-wrap attached). When

ESD/EMI Protection

developing applications, the user must provide for proper ESD
protection on external, user-accessible I/Os (e.g. suppressor arrays for
the I/Os).
The components are mounted on a multilayer PCB to provide a stable ground
plane for onboard components. The module features several GND pins next to
pins with higher switching frequency for short ground returns. If unused, the clock
output can be separated from the module header by removing a series resistor on
the module. Removing the series resistor further reduces electromagnetic emissions.
Absolute Maximum Ratings
Stresses greater than those listed in Table 6 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).
