LonWorks Twisted Pair Control Module User's Guide 17
The supply current requirements for the control modules are outlined in Table 8 ,
which includes peak requirements for the different operating states of the
Neuron Chip. The control modules require a 5 V ±5% power supply. The current
requirements are characterized for maximum number of devices on the channel
with I/O pins programmed as outputs at a logic low level with no load.
The values in
Table 8 are subject to change. Please consult current data sheets
for the latest information.
Table 8 . Typical Control 5 Volt Current Requirements
Control Module Typical DC Characteristics (+5.0 V)
Active, Receive (mA) Active, Transmit (mA)
TP/FT-10 (5 MHz) 25 40
TP/FT-10F (10 MHz) 50 60
TP/XF-78 (5 MHz) 35 45
TP/XF-78F (10 MHz) 50 60
TP/XF-1250 (10 MHz) 55 80
Notes :
1. Assumes internal I/O pullups are disabled and I/O lines are not connected
to a load.
2. Assumes SERVICE~ pullup is enabled.
3. Includes CMOS EPROM or flash chip running typical application with
system code.
4. These figures include typical PROM current consumption of 4 mA at 5
MHz or 5 mA at 10 MHz; the TP/FT-10F and TP/XF-78F figures include
flash memory reads, however, flash memory writes require an
additional 50 mA . These figures exclude current due to loading on the
I/O connector pins.
