PIC18F2220-I/SP - PIC18F2220 Flash 28-pin 4kB Microcontroller

Product Details

The Microchip PIC18F2220 Microcontroller is an advanced 28-pin 8-bit PIC Microcontroller featuring nanoWatt technology for reduced power consumption. The PIC18F2220 has 4 kBytes of Flash Program Memory and a Ten Channel 10-bit Accuracy A/D Converter, together with an Addressable USART module for RS-232 communication on a bus system. The microcontroller has a total of 25 I/O pins available with individual direction control and are suitable for directly driving LEDs.
