STR730FZ1T7 Datasheet, PDF (13/22 Pages) STMicroelectronics – ARM7TDMI 32-BIT MCU WITH FLASH, 3x CAN, 4 UARTs, 20 TIMERS, ADC, 12 COMM. INTERFACES

STR73xF Data Brief
Legend / Abbreviations for Table 3:
Type:
I = input, O = output, S = supply, HiZ= high impedance,
In/Output level: T_T= TTL 0.8V / 2V with input trigger
C_T= CMOS 0.3V_DD/0.7V_DD with input trigger
Port and control configuration:
– Input:
pu/pd = with internal 100kΩ weak pull-up or pull down
– Output:
OD = open drain (logic level)
PP = push-pull
Interrupts:
INTx =external interrupt line
WUPx =Wake-Up interrupt line
The reset state of the I/O ports is input floating. To avoid excess power consumption, unused I/O ports
must be tied to ground.
