It operates up to 64 MHz (16 MIPS) with an internal oscillator or external clock. Communication peripherals include two Enhanced USART modules with auto-wake on sync break and two Master Synchronous Serial Port (MSSP) modules supporting both SPI and I2C master\/slave modes. The 10-bit ADC provides 11 analog input channels with programmable acquisition time. Two Enhanced Capture\/Compare\/PWM (ECCP) modules offer advanced PWM with dead-band control for motor drive applications. The nanoWatt XLP technology enables ultra-low-power sleep modes with fast wake-up. Packaged in 28-pin SOIC rated for -40C to +85C.","working_principle":"The PIC18F25K22 uses Microchips enhanced PIC18 core with a 16-bit instruction word and two-stage pipeline. Most instructions execute in a single cycle at 64 MHz (16 MIPS). The 64KB Flash uses a linear addressing scheme eliminating bank switching for program memory. The two MSSP modules operate independently, allowing simultaneous SPI and I2C communication. The ADC uses a successive approximation register (SAR) architecture with programmable acquisition time and auto-conversion on timer trigger for precise sampling intervals. The ECCP modules generate PWM with up to 10-bit resolution and half-bridge\/full-bridge output modes with programmable dead-band delay for motor drive FET switching. The XLP sleep mode shuts down all oscillators while maintaining RAM and register contents, with watchdog timer or pin-change wake-up.","pin_description":" 28-pin SOIC with 25 GPIO: Port A (RA0-RA7 with ADC\/ref\/osc), Port B (RB0-RB7 with ICSP\/interrupts\/KB), Port C (RC0-RC7 with UART\/SPI\/I2C\/PWM), plus MCLR, VDD\/VSS (multiple).
