Break ST72F321J9 Microcontroller Flash/ROM Memory and extract embedded data from secured flash controlled by microprocessor ST72F321J9, and then crack secured mcu st72f321j9 security fuse bit;

PIN DESCRIPTION (Cont’d)

For external pin connection guidelines, refer to See “ELECTRICAL CHARACTERISTICS” on page 113.

Legend / Abbreviations for Table 1:

Type:                 I = input, O = output, S = supply

Input level:         A = Dedicated analog input In/Output level: C = CMOS 0.3VDD/0.7VDD

CT= CMOS 0.3VDD/0.7VDD with input trigger Output level:                        

HS = 20mA high sink (on N-buffer only)

Port and control configuration:

• Input:          
• float = floating, wpu = weak pull-up, int = interrupt 1), ana = analog ports
• Output:        OD = open drain 2), PP = push-pull

Refer to “I/O PORTS” on page 42 for more details on the software configuration of the I/O ports.

The RESET configuration of each pin is shown in bold. This configuration is valid as long as the device is in reset state.

1. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up column (wpu) is merged with the interrupt column (int) when breaking st72f32ak1 microcontroller flash memory, then the I/O configuration is pull-up interrupt input, else the configuration is floating interrupt input.
2. In the open drain output column, “T” defines a true open drain I/O (P-Buffer and protection diode to VDD are not implemented). See See “I/O PORTS” on page 42. and Section 12.8 I/O PORT PIN CHARACTER- ISTICS for more details.
3. OSC1 and OSC2 pins connect a crystal/ceramic resonator, or an external source to the on-chip oscil- lator; see Section 1 INTRODUCTION and Section 12.5 CLOCK AND TIMING CHARACTERISTICS for more details.
4. On the chip, each I/O port has 8 pads. Pads that are not bonded to external pins are in input pull-up configuration after reset and restore st72f32ak2 mcu encrypted flash heximal. The configuration of these pads must be kept at reset state to avoid added current consumption.
