BL1–BL4 Pins
These signals are used to indicate the current status of the battery to the ÉlanSC310
microcontroller. A high signal indicates normal operating conditions, while a low
indicates a warning condition. Access to these signals has been provided on the
evaluation board to allow designers to test their functionality. Switches 4–7 on
SW4 allow the BL1–BL4 signals to be toggles between GND (warning) and 5 V
(normal).
Breadboard Area
A breadboard area has been provided on the ÉlanSC310 microcontroller evaluation
board. This area can be used as a convenient place to build custom circuits to
interface to the evaluation board. The pins in this breadboard are all isolated from
other pins and the rest of the board.
Power Management
The ÉlanSC310 microcontroller offers unparalleled power management in its class.
In addition to low operating current, six power management modes are available:
High Speed, Low Speed, Doze, Sleep, Suspend, and Off. Refer to the ÉlanSC310
Microcontroller Data Sheet and Programmer’s Reference Manual for an in-depth
discussion of these modes.
