Description PIC18F2221/2321/4221/4321 8 The PIC18F microcontroller from Microchip is the most powerful 8-bit device in Microchip's product line. The CAN, LIN, and Ethernet functions included in this series are part of the complete series of peripheral devices, which can meet the needs of embedded applications and versions. It adopts XLP (Ultra Low Power) technology for applications where power consumption is a key consideration. The PIC18F2221/2321/4221/4321 series microcontrollers are based on Microchip's PIC18 architecture, providing a 31 level hardware stack and 77 instructions. These MCUs provide up to 10 MIPS, up to 8 kb of program memory, 512 kb of RAM, and 256 kb of data EEPROM. Onboard configurable oscillator with an accuracy of ± 1%. ###Microcontroller function 40 MHz maximum CPU speed 77 instructions 31 level hardware stack configurable internal oscillator - optional frequency range 8 mHz to 31 kHz 25 input/output pins - PIC18F2221/2321 model 36 input/output pins - PIC18F4221/4321 model nanoWatt XLP technology power on reset (POR) power on timer (PWRT) oscillator start timer (OST) power off reset (BOR) extended monitoring timer (WDT) low voltage programming (LVP) online serial programming (ICSP) online debugging (ICD) # # # peripheral 10 bit analog-to-digital converter (ADC) - PIC18F2221/2321 10 channel; PIC18F4221/4321 13 channel enhanced acquisition, comparison, PWM module - PIC18F4221/4321 model only acquisition, comparison, PWM module - PIC18F2221/2321 x 2, PIC18F4221/4321 x 1 Two comparators, one 8-bit timer, three 16 bit timers, high/low voltage detection (HLVD) module, main synchronous serial port (MSSP) module, with SPI and I2C enhanced universal synchronous asynchronous receiver transmitter (EUSART) # # # PIC18 microcontroller
