47.11.1 Master Clock Characteristics
47.11.2 I/O Characteristics
Criteria used to define the maximum frequency of the I/Os:
Output duty cycle (40%-60%)
Minimum output swing: 100 mV to V
VDDIO
- 100 mV
Minimum output swing: 100 mV to V
VDDIO
- 100 mV
Addition of rising and falling time inferior to 75% of the period
Notes:
1. Pin Group 1 = PA14, PA29
2. Pin Group 2 = PA[4], PA[9-11], PA[15-25], PB[0-7], PB[12-13], PC[0-31], PD[2], PD[18:31], PE[0-5]
3. Pin Group 3 = PA[5:8], PA[12-13], PA[26-28], PA[30-31], PB[8:9], PB[14], PD[0:1], PD[3:17]
4. Pin Group 4 = PA[0-3]
5. Pin Group 5 = PB[10-11]
