Microcontroller PIC18F13K50 Flash Memory Attacking needs to crack pic18f13k50 protective system and read embedded heximal from mcu pic18f13k50;

• 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 1K for program memory and 100K for EEPROM. Data retention without refresh is conservatively estimated to be greater than 40 years which has provide the PIC18F2520 flash binary recovery become possible.
• Self-programmability: These devices can write to their own program memory spaces under internal software control. Using a bootloader routine located in the code protected Boot Block, it is possible to create an application that can update itself in the field.
• Extended Instruction Set: The PIC18(L)F1XK50 family introduces an optional extension to the PIC18 instruction set, which adds eight new instructions and an Indexed Addressing mode. This extension 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 four outputs to provide the PWM signal.
• Enhanced Addressable USART: This serial communication module is capable of standard

RS-232 operation and provides support for the LIN bus protocol. Other enhancements include automatic baud rate detection and a 16-bit Baud Rate Generator for improved resolution.

• 10-bit A/D Converter: This module incorporates programmable acquisition time, allowing for a channel to be selected and a conversion to be initiated without waiting for a sampling period and thus, reduce code overhead.

Extended Watchdog Timer (WDT): This enhanced version incorporates a 16-bit postscaler, allowing an extended time-out range that is stable across operating voltage and temperature.
