Product Details

PIC18F2221/2321/4221/4321 8-Bit Microcontrollers

The PIC18F Microcontrollers from Microchip are the most capable 8-bit devices within Microchip’s offer. Available within the range is CAN, LIN and Ethernet capability as part of a comprehensive range of peripherals to meet the needs of embedded applications and versions featuring XLP (Extreme Low-Power) Technology for where power consumption is a key consideration.

The PIC18F2221/2321/4221/4321 family of Microcontrollers is based upon Microchip’s PIC18 architecture offering a 31 level hardware stack and 77 instructions. These MCUs provide up to 10 MIPS, up to 8 Kbytes program memory with 512 bytes RAM and Data EEPROM of 256 bytes. On board is a configurable oscillator with ±1% accuracy.
