16 Power Requirements
FT 5000 Control Module
The following sections describe the power requirements for the FT 5000 Control
Module.
Control Module Power Requirements
FT 5000 Control Modules require a +3.3 VDC power source with sufficient
current to power the control module in all modes of operation.
The supply current requirements for the FT 5000 Control Modules are outlined
in Table 7, including typical requirements for the different operating states of
the FT 5000 Smart Transceiver at various system clock rates.
Table 7. FT 5000 Current Requirements
Active SysClk Typical Maximum
Receive Current
5 MHz 9 mA 15 mA
10 MHz 9 mA 15 mA
20 MHz 15 mA 23 mA
40 MHz 23 mA 33 mA
80 MHz 38 mA 52 mA
Transmit Current 5 – 80 MHz
Receive Current
+ 15 mA
Receive Current
+ 18 mA
The FT 5000 Control Module requires a 3.3 V nominal power supply (3.0 V to 3.6
V range). The current requirements assume no load on digital I/O pins, and that
the I/O lines are not switching. In addition, the current consumption in transmit
mode represents a peak value rather than a continuous usage value because an
FT 5000 Smart Transceiver does not typically transmit data continuously.
Note that the stated current requirements do not include the requirements for
performing reads or writes to the external memory (the two-wire serial
EEPROM), which typically add 1 to 2 mA. When not in use, the EEPROM
typically requires only 2 μA.
Neuron 3150 Control Modules
The following sections describe the power requirements for the Neuron 3150
Control Modules.
Control Module Power Requirements
Twisted Pair Control Modules require a +5 VDC power source with sufficient
current to power the control module in all modes of operation.
