Features & Applications
PIC18F24K20-I/SO is a 8-bit Microcontroller has 16 KBytes of Flash Program Memory with 25 I/O's. It's maximum CPU speed is 64 MHz with an operating voltage range of 1.8 V - 3.6 V in a 28-Pin SOIC package. It has an industrial temperature ranges from (-40°C to +85°C).


PIC18F2XK20/4XK20 devices can be programmed using either the high-voltage In-Circuit Serial Programming method or the low-voltage ICSP method. Both methods can be done with the device in the user's system.
