IRROFF is set to VDD, this value can be lowered to 1.7 V when the device operates in the 0 to 70 °C temperature range. a reduced temperature range. 2. When the ADC is used, refer to Table 64: ADC characteristics. 3. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV between VDD and VDDA can be tolerated during power-up and power-down operation. 4. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax. 5. In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax. Table 12. General operating conditions (continued) Symbol Parameter Conditions Min Max Unit Table 13. Limitations depending on the operating power supply range Operating power supply range ADC operation Maximum Flash memory access frequency (fFlashmax) Number of wait states at maximum CPU frequency (fCPUmax= 120 MHz)(1) I/O operation FSMC_CLK frequency for synchronous accesses Possible Flash memory operations VDD =1.8 to 2.1 V(2) Conversion time up to 1 Msps 16 MHz with no Flash memory wait state 7(3) – Degraded speed performance – No I/O compensation up to 30 MHz 8-bit erase and program operations only VDD = 2.1 to 2.4 V Conversion time up to 1 Msps 18 MHz with no Flash memory wait state 6(3) – Degraded speed performance – No I/O compensation up to 30 MHz 16-bit erase and program operations |
