PIC18F2525/2620/4525/4620 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 PIC18F2525/2620/4525/4620 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 with RAM of 3968 bytes and data EEPROM of 124 bytes. On board is a configurable RC oscillator.
