12 POWER CONSUMPTION MEASUREMENTS
The following values are actual current measurements for the oxcb950 device using prototype test boards. These values are to
be treated as indicators and do not necessarily represent actual figures or incur statistical spreads associated with production
parts.
12.1 Static current consumption
• DC current with the PCI clock and XTLI pins grounded
• Current drawn with the XTL1 Pin grounded but with the PCI interface clock running.
100uA
7.8mA
12.2 Current consumption in application
• Current when no accesses have been made to the UART and the UART
automatically enters its sleep state.
• Current when the UART is in full operation, transmitting and receiving via internal
loopback at maximum data rate (DLLDLM=1).
• Current when the UART divisor latch has been set to maximum divide and the UART
is in full speed operation.
• Current when the (UART) power management state is configured to power states D2
• Current when the (UART) power management state is configured to power states D3
4.5mA
14mA
12mA
3.2mA
3.2mA
