Microchip, 8bit PIC, PIC18F Microcontroller, 40MHz, 32 kB, 256 B Flash, 28-Pin SOIC

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 32 Kbytes program memory with RAM of up to 1536 bytes and 256 bytes of Data EEPROM. On board is a configurable oscillator.
