A Low enables a write to on-chip Flash
memory. If this pin is unconnected, on-chip
Flash memory is write-protected.
Notes:
1. External capacitive loads on RD, WR, IORQ, MREQ, D0–D7, and A0–A23 must be below 10 pF to satisfy timing
requirements for the CPU.
2. All unused inputs must be pulled to either VDD or GND, depending on their inactive levels, to reduce power
consumption and to reduce noise sensitivity.
3. All inputs are CMOS level 3.3 V (5 V-tolerant), except where otherwise noted.

Input/Output Connector
Figure 3 presents a pin layout of the 60-pin I/O connector (J2) of the modules. However,
the eZ80® Development Platform features a 50-pin connector. eZ80Acclaim!™/
eZ80AcclaimPlus!™ Ethernet Modules are designed to interface pin 60 of their J2 connectors to pin 50 of the eZ80 Development Platform’s JP2 connector so that pins 1–10 of the
Modules overlap the edge of the eZ80 development platform. Table 2 describes the pins.

requirements for the CPU.
2. All unused inputs must be pulled to either VDD or GND, depending on their inactive levels, to reduce power
consumption and to reduce noise sensitivity.
3. All inputs are CMOS level 3.3 V (5 V-tolerant), except where otherwise noted.

eZ80Acclaim!™/eZ80AcclaimPlus!™ Ethernet Modules
Product Specification
Onboard Component Description
This chapter describes each individual component of the eZ80Acclaim!™/
eZ80AcclaimPlus!™ Ethernet Module.
Logic-Level Input/Outputs
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 about the
eZ80Acclaim!™ MCU, refer to the eZ80F91 MCU Product Specification (PS0192). To learn
more about the eZ80AcclaimPlus!™ MCU, refer to the eZ80F91 ASSP Product Specification
(PS0270).
Onboard Battery Backup
An onboard Panasonic ML2020 3 V Lithium battery powers the 32 kHz real-time clock
when external power is removed. The battery is charged through diode D2 and resistor
R17 when external power is applied to the board.
Ethernet PHY and RJ45 Connector
The Module is equipped with an RJ45 connector with integrated magnetics and two LEDs
manufactured by IDT.
Ethernet LEDs
Ethernet activity is indicated by two LEDs located on the RJ45 connector. When the PHY
is receiving data, the green LED is ON. When the PHY is transmitting data, the yellow
LED is ON.
Fast Buffer (U6)
The eZ80Acclaim!™/eZ80AcclaimPlus!™ Ethernet Module features a fast buffer (see Figure 1 on page 3) that is used to prevent bus contention that can occurs due to slow turn-off
time of the module’s external Flash memory, and the fast bus turn-around time of the
PS030603-1013
12
eZ80Acclaim!™/eZ80AcclaimPlus!™ Ethernet Modules
Product Specification
eZ80F91 MCU (i.e, a generic feature of the eZ80® family when it is used in NATIVE
Mode).
When developing with the eZ80 family of products in NATIVE Mode, the challenge with
bus contention occurs when two or more devices drive a common bus. The eZ80F91
MCU’s CS0 drives the Flash CE. After accessing the Flash memory space, CS0 is driven
High a maximum of 8.8 ns after the next rising edge of the clock (refer to T6 in Figure 4).
The Flash turn-off time (TOD) is 25 ns, which is the period from OE or CE going High to
the Flash output drivers going into High-Z Mode. In essence, after the end of the MCU’s
read access to Flash, a period of 8.8 ns + 25 ns = 33.8 ns must occur before Flash memory
stops driving the data bus. At this point, the eZ80F91 device is already well into the next
bus cycle.

Fast Buffer Feature
During a memory write cycle, data (output) from the eZ80F91 device is valid not later
than T3 = 7.5 ns, and the write pulse is asserted not later than 4.5 ns after the falling edge
of the Clock (14.5 ns from the rising edge if Clock is 50 MHz). The result is that during
TCON = (33.8 ns – 7.5 ns) = 26.3 ns, two devices drive the common data bus: the eZ80F91
MCU itself, and Flash memory. In turn, data that is being written during the write opera-
PS030603-1013
13
eZ80Acclaim!™/eZ80AcclaimPlus!™ Ethernet Modules
Product Specification
tion could become corrupted. The part used to isolate a slow Flash data bus from a fast
eZ80F91 bus has a 5.5 ns turn-off time, which reduces the 25 ns duration of the TCON to
5.5 ns. As a result, bus contention still occurs, but its duration is not 26.3 ns, as described in
the following equation:
Time of contention = (8.8 ns – 7.5 ns + 5.5 ns = 6.8 ns
Data being written is not corrupted because the write pulse is not yet asserted.
For more information about bus contention on the eZ80Acclaim!™ MCU, refer to the eZ80F91
MCU Product Specification (PS0192). To learn more about bus contention on the
eZ80AcclaimPlus!™ MCU, refer to the eZ80F91 ASSP Product Specification (PS0270).
Memory
The Module’s onboard memory consists of the following components:
•
•
•
U4, CY7C1049: 512 KB SRAM with a 10 ns access time
U5, S29GL064N: 8 MB NOR Flash with 90 ns access time
U3, S25FL032: 32 Mb NAND Flash with an SPI interface
The Module contains external Flash memory, and the eZ80F91 MCU contains internal Flash
memory. To allow read/write access to Flash memory on the Module, there are two signals
provided, on connectors J1 and J2. A jumper on the module, JP3, enables the programming of
on-chip Flash. There is also a signal that duplicates the function of this JP3 jumper. Table 3
indicates the states of the signals and the status of the JP3 jumper for different modes.

The external Flash memory space of the eZ80Acclaim!™/eZ80AcclaimPlus!™ Ethernet
Module has an access time of 90 ns. At least five wait states must be added to the cycle
when accessing external Flash at 50 MHz clock speed. The eZ80F91 devices on-chip Flash

is faster; its minimum access time is 60 ns, which requires only three wait states at
50 MHz.
The Modules feature 512 KB of fast SRAM. Access time is 10 ns, which requires onewait-state access. The eZ80F91 MCU’s on-chip SRAM is used with zero wait states. An
additional memory component on the Module is NAND Flash memory with an SPI interface. This 32 Mb device is manufactured by Spansion.
Serial Interface Ports
The CPU 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 RS-232 level
shifters on the eZ80Acclaim!™/eZ80AcclaimPlus!™ Ethernet Module.
Physical Dimensions
The footprint of each Modules’ PCB is 63.5 mm x 78.7 mm. With an RJ-45 Ethernet connector, the overall height is 25 mm, see Figure 5.

Stresses greater than those listed in Table 4 causes 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 must be tied to one of the supply voltages (VDD or VSS).
