TS-7250 MANUAL
CONNECTORS AND HEADERS
5.10 Power Supply Header
The
TS-7250
requires regulated 5VDC at 450 mA @ 200 MHz(maximum). It is possible to
lower this power significantly by lowering the CPU clock rate or by powering-down the
Ethernet PHY chip. For example, by shutting down the Ethernet PHY chip and scaling
down the CPU clock rate to 20 MHz, one can obtain power consumptions less than 150
mA. If you really need a low-power board, consider the
TS-7260
, which is optimized for
low power applications.
A quick release screw-down terminal block for the 5V power and power GND connections
is provided for easy connection to an external power supply.
!
Warning
Supply voltages over 6 VDC may damage the
TS-7250
.
Be sure to use a regulated 5 VDC power supply, preferably with current limiting to 1 to 3
Amps. A current limited supply is very forgiving of common errors during development. A
PC power supply that may be capable of supplying 20 Amps or more is not
recommended. It is possible to do irreversible damage to the
TS-7250
if the polarity on the
power leads is reversed.
