Features & Applications
The PIC18F2321-I/SS is a part of PIC18F series 8-bit Microcontroller. It has 8 Kbytes of Flash Program Memory in a 28 Pin SSOP package. It has an industrial temperature ranges from -40°C to +85°C.

The PIC18F2321 is a powerful 10 MIPS (100 nanosecond instruction execution), yet easy-to-program (only 77 single word instructions) CMOS Flash-based 8-bit microcontroller into an 28-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX, PIC16CXX and PIC17CXX devices and provides a seamless migration path of software code to higher levels of hardware integration.
