1 Introduction
The CM-BF527 is a member of Blackfin based core modules incorporating the consumer temperature
version of the ADSP-BF527 (optional also ADSP-BF525 or ADSP-BF522). It is backwards compatible to
the CM-BF537E for most of its interfaces and can be used as a replacement module on any Bluetechnix
development or evaluation Board. A special feature of this module is the on-board 10/100Mbit Ethernet
interface which includes the physical transceiver chip and USB2.0 OTG Interface. The module allows
easy integration into high demanding applications where space and power are very limited.

2 Specification
2.1
Functional Specification
Figure 2-1: Detailed Block Diagram
Figure 2-1 shows a detailed block diagram of the CM-BF527 module. Besides the SDRAM control pins
and the Pins used by the Ethernet Physical Transceiver (Port H) the CM-BF527 has all other pins of the
Blackfin processor on its two main 60 pin connectors.
A special feature of the CM-BF527 Core Module is the on-board physical Ethernet transceiver from
Micrel (KSZ8721BLI).
Dynamic voltage control allows reduction of power consumption to a minimum adjusting the core
voltage and the clock frequency dynamically in accordance to the required processing power. A low
voltage reset circuit guarantees a power on reset and resets the system when the input voltage drops
below 2.93V.
2.2
Boot Mode
By default the boot mode = 0000 (BMODE3 = low, BMODE2 = low, BMODE1 = low, BMODE0 = low). All
BMODE pins have internal pull down resistors.

*) Please be aware that you have to unlock the flash before starting an erase process!
The maximum amount of memory addressable by a single asynchronous memory bank, of the Blackfin
processor is 2MB. In order to be able to use more than 2MB on a single bank, 2 GPIOs are used to select
which 2MB section of flash is visible in the memory window of the Blackfin processor. This frees up the
remaining banks for the user.

Please do not use the PH9 and PG11 pins as IO flags. You should leave these Pins disconnected! If one or
both IO pins are needed and 4MB or 2 MB flash memory is sufficient for your application, remove the 0Ω
resistors R26 and R19 from your Core Module. The flash address lines A20 and A21 are pulled Low.
To access more than 8MB flash memory (64MB) you can add the 0Ω resistor array R2. But be aware to
not connect the IO pins PG10, PG9 and PG1.

1)
Internally connected to 2.5V. If you want to program the OTP memory, just power this pin with 7.0V.
2)
These IO pins are normally used to access more flash memory. They should not be used as general
purpose IO pins. For more information please see chapter 2.3.
3.4.2 Connector X3 – (61-120)
Please mind the mounted pull up and pull down resistors on the Core Module. See the third column of

4 Software Support
4.1
BLACKSheep
The Core Module is delivered with a pre-flashed basic version of the BLACKSheep VDK multithreaded
framework. It contains a boot-loader for flashing the Core Module via the serial port.
The BLACKSheep for the CM-BF527 contains also a web server. By typing http://192.168.0.10 you can
see a standard web page installed on the Core Module.
Please consult the software development documents.
4.2
uClinux
The Core Module is fully supported by the open source platform at http://blackfin.uclinux.org. Since the
Core Modules are pre-flashed with BLACKSheep you have to flash uBoot first. To flash the uBoot you can
use the BLACKSheep boot-loader.
