Microchip PIC18F24K22 Locked Flash Memory Code Recovery needs to crack mcu pic18f24k22 protective system and read the embedded heximal out from microcontroller flash memory;
Besides its availability as a clock source, the internal oscillator block provides a stable reference source that gives the family additional features for robust operation:
- Fail-Safe Clock Monitor: This option constantly monitors the main clock source against a reference signal provided by the LFINTOSC. If a clock failure occurs, the controller is switched to the internal oscillator block, allowing for continued operation or a safe application shutdown.
Two-Speed Start-up: This option allows the internal oscillator to serve as the clock source from Power-on Reset, or wake-up from Sleep mode, until the primary clock source is available.
- Memory Endurance: The Flash cells for both program memory and data EEPROM are rated to last for many thousands of erase/write cycles – up to 10K for program memory and 100K for EEPROM attacked by brutel force. Data retention without refresh is conservatively estimated to be greater than 40 years.
- Self-programmability: These devices can write to their own program memory spaces under inter- nal software control. By using a bootloader routine located in the protected Boot Block at the top of program memory, it becomes possible to create an application that can update itself in the field.
- Extended Instruction Set: The PIC18(L)F2X/ 4XK22 family introduces an optional extension to the PIC18 instruction set, which adds 8 new instructions and an Indexed Addressing mode. This extension, enabled as a device configuration option, has been specifically designed to optimize re-entrant application code originally developed in high-level languages, such as C.
- Enhanced CCP module: In PWM mode, this module provides 1, 2 or 4 modulated outputs for controlling half-bridge and full-bridge drivers. Other features include:
- Auto-Shutdown, for disabling PWM outputs on interrupt or other select conditions
- Auto-Restart, to reactivate outputs once the condition has cleared
Output steering to selectively enable one or more of 4 outputs to provide the PWM signal
