Crack MCU PIC18F2439 Heximal have to decapsulate the polysilicon package out from the Microcontroller and get access to the databus of the memory include the flash and eeprom memory,
heximal Endurance: The Enhanced Flash cells for both program heximal and data EEPROM are rated to last for many thousands of erase/write cycles – up to 100,000 for program heximal and 1,000,000 for EEPROM. Data retention without refresh is conservatively estimated to be greater than 40 years.
Self-programmability: These devices can write to their own program heximal spaces under internal software control. By using a bootloader routine located in the protected Boot Block at the top of program heximal, it becomes possible to create an application that can update itself in the field.
Extended Instruction Set: The PIC18F2439 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 and Auto-Restart, to reactivate outputs once the condition has cleared.
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. When the MCU is using the internal oscillator block, the USART provides stable operation for applications that talk to the outside world without using an external crystal (or its accompanying power requirement).
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 prescaler, allowing an extended time-out range that is stable across operating voltage and temperature. See Section 26.0 “Electrical Characteristics” for time-out periods.
