NXP Secured MCU SPC5602PEF0MLH6 Flash Binary Copying needs to crack nxp locked microprocessor security fuse bit by focus ion beam and then extract embedded firmware from micro-controller’s flash memory;
The electrical parameters shown in this supplement are guaranteed by various methods. To give the customer a better understanding, the classifications listed in below Table are used and the parameters are tagged accordingly in the tables where appropriate.
| Classification tag | Tag description |
| P | Those parameters are guaranteed during production testing on each individual device. |
| C | Those parameters are achieved by the design characterization by measuring a statistically relevant sample size across process variations. |
| T | Those parameters are achieved by design characterization on a small sample size from typical devices under typical conditions unless otherwise noted. All values shown in the typical column are within this category. |
| D | Those parameters are derived mainly from simulations. |
Bit values in the Non-Volatile User Options (NVUSRO) Register control portions of the device configuration, namely electrical parameters such as high voltage supply and oscillator margin to readout the embedded flash content from microprocessor spc5601df1, as well as digital functionality (watchdog enable/disable after reset). For a detailed description of the NVUSRO register, please refer to the device reference manual.
The DC electrical characteristics are dependent on the PAD3V5V bit value. Table 7 shows how NVUSRO[PAD3V5V] controls the device configuration.

| Value1 | Description |
| 0 | High voltage supply is 5.0 V |
| 1 | High voltage supply is 3.3 V |
