Description - (Input or Output)
Factory test pin - leave unconnected (I)
Digital supply voltage (same as AVDD) (i)
Not used - leave unconnected (NC)
Digital ground reference (same as AVSS) (I)
EnerChip charge indicator, pin pulses low in response to STATUS SW/ (O)
Enable Capacitor Charge goes low while charging the output capacitor (O)
Tie this pin to DVDD through a 100kΩ resistor (I)
Voltage generator input - range 0V to 2.5V (I)
Maximum Peak Power Tracking indicator (O)
EnerChip charge voltage feedback input (I)
Capacitor Charge indicator; this pin pulses low in response to STATUS SW/ (O)
Not used - leave unconnected
Not used - leave unconnected
Status state switch (see Status Indicators section) (I)
Analog ground reference - tie to system ground (same as DVSS) (I)
Analog supply voltage (same as DVDD) (I)
Not used - leave unconnected
Not used - leave unconnected
Not used - leave unconnected
Not used - leave unconnected
Not used - leave unconnected
Not used - leave unconnected
Not used - leave unconnected

Serial I/O transmit data out of the Energy Processer Data rate is 9600 8N1 (O)
Serial I/O receive data into the Energy Processer Data rate is 9600 8N1 (I)
A high level will cause the EnerChip to disconnect from the system load (O)
Used in conjunction with MODE SEL1 to select transducer type (I)
Used in conjunction with MODE SEL0 to select transducer type (I)
Output capacitor feedback monitor (I)
A high level will isolate all loads from the Energy Processer (0)
Not used - leave unconnected (future product enhancement) (NC)
A high level will force the EnerChip to connect to the system load (O)
Boost converter switch driver (O)
Only used in target system calibration (see Calibration Function section) (I)
When high connects the VCAP A/D pin to the output capacitor (O)
Not used - leave unconnected (future product enhancement) (I)
When low connects power to the application system (O)
