2 Specification
2.1
Figure 2-1 shows a detailed block diagram of the CM-BF537E module. Other than the SDRAM control pins the
CM-BF537E has all other pins of the Blackfin processor on its two main 60 pin connectors.
A special feature of the CM-BF537E Core Module is the on-board physical Ethernet transceiver from Micrel
(KSZ8041BL).
Dynamic voltage control allows reducing 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 = 000 (BMODE2 = low, BMODE1 = low, BMODE0 = low). All BMODE pins have
internal pull down resistors.
Connect BMODE0 to Vcc and leave BMODE1, BMODE2 pins open for boot mode 001 equals to 8 or 16 bit
PROM/FLASH boot mode, this is the default boot mode of the Blacksheep software. See Blackfin Datasheets
or Eval/DevBoard manuals for more details.
