It features 128KB of Flash program memory, 3,862 bytes of RAM, and 1,024 bytes of data EEPROM. The device integrates a 12-bit ADC with up to 30 input channels, two comparators, and a USB 2.0 Full-Speed device interface. Dual EUSART modules support LIN protocol, and dual MSSP modules provide SPI and I2C connectivity. The 68 I\/O pins with Peripheral Pin Select (PPS) on select peripherals allow flexible board routing. The -PTRSL suffix indicates tape and reel packaging with automotive-grade qualification. The device operates from 1.8V to 5.5V, making it suitable for both 3.3V and 5V systems. The extended instruction set with 16-level hardware stack and two levels of interrupt priority enable efficient real-time application development.","working_principle":"The PIC18F87K22-I\/PTRSL operates as a high-performance 8-bit PIC18 microcontroller. (1) PIC18 Core: The CPU executes an extended 83-instruction set with most instructions executing in a single cycle (4 clock edges). A 16-level hardware stack supports nested subroutine calls. Two interrupt priority levels allow time-critical interrupts to preempt lower-priority ones. (2) 12-bit ADC: The successive approximation ADC converts analog inputs to 12-bit digital values. The 30-channel input multiplexer allows monitoring multiple analog signals. The ADC supports automatic acquisition timing and can be triggered by timers or PWM events. (3) USB 2.0: The integrated USB transceiver and protocol engine handle USB Full-Speed (12Mbps) communication. The device supports 16 bidirectional endpoints with integrated FIFO buffers. (4) Peripheral Pin Select (PPS): Select digital peripheral inputs and outputs can be remapped to any of the available I\/O pins through configuration registers, providing PCB layout flexibility.","pin_description":"
