PIC18F4550-I/P

Microchip Technology

PIC18F4550-I/P is the PDIP-40 through-hole order code for Microchip's PIC18F4550 8-bit microcontroller with full-speed USB — for legacy USB device designs, data acquisition and human-interface hardware that was laid out around the 40-pin DIP, and for service replacement of socketed parts. The integrated USB 2.0 device peripheral with 32 KB Flash is the selection point: native USB without an external bridge chip, in the package that anchored countless DIY and industrial USB projects. Selection advice: the I/P suffix denotes the industrial temperature grade (-40 to +85 °C) in PDIP-40; the surface-mount sibling PIC18F4550-I/PT (TQFP-44) is on this site, and a QFN-44 code (I/ML) also exists in the DS39632 ordering system — match the full code to your board, since none of the three packages interchange. Confirm your USB class and driver needs against the datasheet, and note the 5 V-tolerant I/O for mixed-voltage designs.
