Hardware Description
Functional
Blocks
Figure 1 shows the V1.1 activity board and its different functional areas.
These areas are detailed in the following sections.
Figure 1 – Top View of the Playground
AVRcard slot
Two 32-pin headers connect to power and ports. A 6-pin header connects
to the CPU reset signal, as there is no reset signal on the standard
connectors of AVRcard. The reset signal is used only in conjunction with the
TCP/IP module.
TCP/IP Module
This slot receives the IIM7010 Ethernet module. Two positions are
provided:
Memory mapped
I2C connection
D-Sub connectors
Two D-Sub connectors, one female and one male, are provided for easy
connection to the two RS-232 interfaces of the AVRcard. Pin assignment of
each connector can be configured by jumpers (J13, J15).
The second D-Sub connector shares its board position with the TCP/IP
Module. If this module is used, the second D-Sub connector can be
connected via the 10-pin header J18.
Power supply
A standard 7805 voltage regulator is provided for the 5V supply. DC power
is applied through the power jack J8. A bridge rectifier ensures correct
polarity.
For the Ethernet-Module, a separate 3.3V regulator is used. A second 3.3V
regulator is used for the MMC.

Hardware Description
External SRAM
The Playground contains a footprint for a 28-pin DIP socket (U3) where an
external SRAM device can be mounted. Make sure the SRAM device has the
same voltage range as the rest of the design.
Note: The SRAM is disabled by default. To enable SRAM support, put a
jumper on J14. The SRAM occupies the memory space from $1000-$7FFF.
LCD
A small alphanumeric LCD (4 lines, 20 characters) can be mounted across
the prototyping area (J25). The connector pinout is designed for the EA
DIP204-4 module from Electronic Assembly. It is connected to the SPI bus.
Please refer to [5] for further details on this display.
Display contrast is adjusted by R5. R4 sets the background LED current.
MMC Connector
An adapter for MultiMediaCards (MMC) can be mounted on position J17.
The MMC is connected to the SPI bus via level converters 74VHC08 (U6).
Bit5 of PortB is used as SS signal in order not to interfer with the standard
SPI Bus Connection.
Header
Connectors
All CPU ports and some additional signals can be connected by standard
0.1” headers. Pin 1 has a square pad.
Port Connectors
The pinout for the I/O port headers is explained in Figure 2. The square
marking indicates pin 1.

A0-7 Connector
The connector J20, marked A0-7 contains the 8 least-significant bits of the
external address bus. The purpose of the connector is to provide easy
access to the address bus. The 8 most significant bits can be found on the
Port C connector J4.
This connector is handy when interfacing external devices.

dedicated connector J12. This pinout is compatible to the modules with I2C
interface from E-Lab Computers. Please refer to [6] for further details on
these modules.

Mode Selection for
Ethernet-Module
When the Ethnernet module is used in memory-mapped mode, closing of
jumper J19 selects the non clocked mode. Please refer to [4] for further
details.
