Description _________________
System Connectivity __________
PowerDsine’s™ Microcontroller Unit, PD63000, is a
member of Motorola’s HCS08 Family of 8-bit
microcontroller units (MCUs). This MCU uses the
enhanced HCS08 core and is pre-programmed with a
special proprietary application. It is used in
conjunction with PowerDsine’s PD64012 PoE
Manager in Ethernet switches and Midspans to allow
next generation network devices to share power and
data over the same cable, according to IEEE 802.3af.
When used in conjunction with the PD63000, the
PD64012 operates in Enhanced mode.
In order to properly relate to the MCU in this
document, a diagram of basic system connectivity is
presented, hereafter. The various port groups are
depicted along with their respective port lines. This
block diagram can be compared with the application
schematics from PowerDsine’s Application Notes and
Data Sheets, so as to understand the circuits used.

The MCU features a 1 Mb/s SPI to each of the PoE
Managers and a communication interface with the
host CPU via UART or I2C protocol. The I/O lines, the
SPI bus and the control signals are loaded by 50-
ohm serial resistors. The MCU runs at about 10 MHz,
providing a 1 MHz clock frequency to the SPI bus. An
external resonator is used for clock generation.

Pin Configuration _____________
Program Burn-in ______________
Initial burn-in is accomplished via the background
header (BDM), by PowerDsine. Thereafter the MCU
is downloaded with a special Powerdsine program
referred to as the PD64012 Enhanced Mode
Software. This software can be downloaded via the
UART port (pins 14 & 15, PTE0/TxD1 & PTE1/RxD1)
or via the I2C port (pins 5 & 6, SDA & SCL.).
