2.2.1 Interface supply voltage - IOVDD

For digital communication with other circuitry (peripherals) the digital I/O configured pins of the mixed signal sensor interface (ADIO0 to ADIO7) and the pins of the serial interface (SCSEDIO0, SCLKDIO1, WSDADIO2, RSDADIO3) may be operated from supply voltages different from DVDD. Therefore an interface voltage supply pin IOVDD is available which can be connected either to DVDD or to an external supply within the tolerated voltage range of IOVDD.

If DVDD=0 V (e.g. in any sleepmode) and IOVDD is supplied, there may be unpredictable and varying current from IOVDD caused by internal floating nodes. It must be taken care that the current into IOVDD does not exceed 10 mA while DVDD=0. If DVDD=0 V and IOVDD is not supplied, do not apply voltage to any above mentioned pin. This may lead to unpredictable malfunction of the device.

In TCM 320/TCM 320C VDD is internally connected to IOVDD! Therefore the above mentioned issues have to be considered when writing own firmware based on API.

IOVDD voltage must not exceed VDD voltage! A malfunction of the module may be caused by such inverse supply!

For I/O pins configured as analog pins the IOVDD voltage level is not relevant!

The operating mode is defined at start-up of the module via a measurement of the voltage at ADIO0.

As long as IDs are stored in ID memory, the operating mode can only be changed after deleting all IDs from memory, e.g. via CLR!
