Crack MCU PIC18F14K50 Heximal from its locked storage memory which include flash and eeprom, then copy the firmware like heximal or binary into blank Microcontroller;
All of the devices in the PIC18F/LF1XK50 family offer ten different oscillator options, allowing users a wide range of choices in developing application hardware.
· Four Crystal modes, using crystals or ceramic resonators
· External Clock modes, offering the option of using two pins (oscillator input and a divide-by-4 clock output) or one pin (oscillator input, with the second pin reassigned as general I/O)
· External RC Oscillator modes with the same pin options as the External Clock modes
· An internal oscillator block which contains a 16 MHz HFINTOSC oscillator and a 31 kHz LFINTOSC oscillator which together provide 8 user selectable clock frequencies, from 31 kHz to 16 MHz. This option frees the two oscillator pins for use as additional general purpose I/O.
· A Phase Lock Loop (PLL) frequency multiplier, available to both the high-speed crystal and internal oscillator modes, which allows clock speeds of up to 48 MHz. Used with the internal oscillator, the PLL gives users a complete selection of clock speeds, from 31 kHz to 32 MHz – all without using an external crystal or clock circuit.
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 1K for program memory and 100K 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 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 PIC18F/ LF1XK50 family introduces an optional extension to the PIC18 instruction set, which adds 8 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 4 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.
