PIC18F2420/2520/4420/4520 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 PIC18F2420/2520/4420/4520 family of Microcontrollers is based upon Microchip’s PIC18 architecture offering a 31 level hardware stack and 75 instructions. These MCUs provide up to 10 MIPS, up to 64 Kbytes program memory RAM of up to 3896 bytes. On board is a configurable oscillator.
