Unlock Microcontroller PIC18F85K22 Flash memory needs to depackage the silicon cap of the MCU PIC18F85K22 by IC breaking method, then cut of the security fuse bit through focus ion beam and then extract firmware from Microprocessor flash memory;
· Communications: The PIC18F87K22 family incorporates a range of serial communication peripherals including two Enhanced USART, that support LIN/J2602, and two Master SSP modules capable of both SPI and I2C™ (Master and Slave) modes of operation.
· CCP Modules: PIC18F87K22 family devices incorporate up to seven Capture/Compare/PWM (CCP) modules. Up to six different time bases can be used to perform several different operations at once if Unlock PIC18F4420 Microcontroller FLASH.
· ECCP Modules: The PIC18F87K22 family has three Enhanced CCP (ECCP) modules to maximize flexibility in control applications:
– Up to eight different time bases for performing several different operations at once
– Up to four PWM outputs for each module – for a total of 12 PWMs
– Other beneficial features, such as polarity selection, programmable dead time, auto-shutdown and restart, and Half-Bridge and Full-Bridge Output modes after reading Microcontroller PIC18F2510 program
· 12-Bit A/D Converter: The PIC18F87K22 family has differential ADC. It 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, reducing code overhead.
· Charge Time Measurement Unit (CTMU): The CTMU is a flexible analog module that provides accurate differential time measurement between pulse sources, as well as asynchronous pulse generation.
· Together with other on-chip analog modules, the CTMU can precisely measure time, measure capacitance or relative changes in capacitance, or generate output pulses that are independent of the system clock.
· LP Watchdog Timer (WDT): This enhanced version incorporates a 22-bit prescaler, allowing an extended time-out range that is stable across operating voltage and temperature. See
Section 31.0 “Electrical Characteristics” for time-out periods.
· Real-Time Clock and Calendar Module
(RTCC): The RTCC module is intended for applications requiring that accurate time be maintained for extended periods of time with minimum to no intervention from the CPU.
· The module is a 100-year clock and calendar with automatic leap year detection. The range of the clock is from 00:00:00 (midnight) on January 1, 2000 to 23:59:59 on December 31, 2099.
All other features for devices in this family are identical.
These are summarized in Table 1-1 and Table 1-2. The pinouts for all devices are listed in Table 1-3 and Table 1-4. Getting started with the PIC18F87K22 family family of 8-bit microcontrollers requires attention to a minimal set of device pin connections before proceeding with development when reading chip PIC18F2610 firmware memory.
