1. The SPI1, SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the I2S audio
mode.
2. Since the LQFP100 package does not feature the PDR_ON pin (tied internally to V
DD
), the minimum V
DD
value for this
package is 1.71 V.
3. V
DD
/V
DDA
can drop down to 1.62 V by using an external power supervisor (see Section 3.5.2: Power supply supervisor)
and connecting PDR_ON pin to V
SS
. Otherwise the supply voltage must stay above 1.71 V with the embedded power
voltage detector enabled.
4. The product junction temperature must be kept within the –40 to +125 °C temperature range.
5. This package is under development. Please contact STMicroelectronics for details.
