32099F–11/2010
Chip
I/O Pins
6. The aWire debug interface is reset after leaving Shutdown mode
1. Power consumption in static mode is too high
2. Shutdown mode is not functional
3. VDDIN current consumption increase above 1.8V
4. Increased Power Consumption in VDDIO in sleep modes
1. PB10 is not 3.3V tolerant
2. Analog multiplexing consumes extra power
3. PA02, PB01, PB04, PB05, and RESET_N have half of the pull-up strength
4. OCD MCKO and MDO[3] are swapped in the AUX1 mapping
If the aWire debug mode is used as debug interface and the program enters Shutdown
mode, the aWire interface will be reset when the device receives a wakeup either from the
WAKE_N pin or the AST.
Fix/Workaround
None.
Power consumption in static mode is too high when PA21 is high.
Fix/Workaround
Ensure PA21 is low.
Do not enter Shutdown mode.
Fix/Workaround
None.
When VDDIN increases above 1.8V, current on VDDIN increases with up to 40µA.
Fix/Workaround
None.
If the OSC0 is enabled in crystal mode when entering a sleep mode where the OSC0 is dis-
abled, this will lead to an increased power consumption in VDDIO.
Fix/Workaround
Solution 1: Disable the OSC0 by writing a zero to the Oscillator Enable bit in the System
Control Interface (SCIF) Oscillator Control Register (SCIF.OSC0CTRL.OSCEN) before
going to any sleep mode where the OSC0 is disabled
Solution 2: Pull down or up XIN0 and XOUT0 with 1Mohm resistor.
PB10 should be grounded on the PCB and left unused.
Fix/Workaround
None.
Current consumption on VDDIO increases when the voltage on analog inputs is close to
VDDIO/2.
Fix/Workaround
None.
Pins PA02, PB01, PB04, PB05, and RESET_N have half of the specified pull-up strength.
Fix/Workaround
None.
When using the OCD AUX1 mapping of trace signals MDO[3] is located on pin PB05
and MCKO is located on PB01.
