... Chapter 1. Introduction and Overview 1.1 INTRODUCTION The PIC18F87J50 FS USB Plug-In Module (PIM) Demonstration Board and Kit is designed as an easy-to-use evaluation platform for Microchip's Full-Speed USB PIC18F87J50 family of microcontrollers. The PIM may be operated either stand-alone conjunction with the HPC Explorer board (microchipDIRECT part number DM183022) ...

... OVERVIEW OF THE PIC18F87J50 FAMILY USB CAPABILITIES The PIC18F87J50 microcontroller is the “superset” device in the PIC18F87J50 micro- controller family. The PIC18F87J50 has the highest memory and pin count in the family, but otherwise shares an identical feature set (except features which require pins not present on 64-pin devices) compared to the other devices ...

... I/O pins on the PIM are directly connected to the same I/O pins on the PIC18F8722 of the HPC Explorer board. For example, when the two boards are connected together, microcontroller pin, RD0 on the PIC18F87J50 FS USB PIM, is directly connected to the RD0 pin on the PIC18F8722, as well as one of the green LEDs on the HPC Explorer board ...

... PROGRAMMING THE MICROCONTROLLER The PIC18F87J50 microcontroller located on the PIM may be reprogrammed in excess of 10,000 cycles. The PIM is too small to feature a full size RJ11 jack used on most Microchip demonstration boards. Instead, the PIM uses a 6-pin right angle male header (J5) which is electrically compatible with common Microchip programmers, such as the ® ...

... Oscillator Configuration The PIC18F87J50 family devices use the same 96 MHz PLL found in prior full-speed USB microcontrollers, such as the PIC18F4550, but the implementation of the surround- ing clock structure is slightly different. When migrating up to the PIC18F87J50 family of devices, the most important change is the PLL does not automatically start when the microcontroller is powered on, even programmed to use one of the PLL-enabled modes (e ...

... Hardware Considerations for Compliance Testing 3.2 HARDWARE FEATURES The PIC18F87J50 FS USB PIM has a number of hardware features intended to make it useful as an initial development platform and demonstration board. Refer to Appendix A. “PIC18F87J50 FS USB Plug-In Module Schematics” for schematics of the PIM. The board offers the following hardware features: 1 ...

... CRYSTAL In order to use the USB module on the PIC18F87J50 family of microcontrollers, the module requires a fixed 48 MHz or 6 MHz clock for use in Full-Speed or Low-Speed modes, respectively. These clock frequencies can be derived from the internal 96 MHz PLL, and the microcontroller core need not run at the same frequency as the USB module ...

... J1 on the HPC Explorer board, the board will natively produce a regulated 5V provided by the on-board adjustable linear regulator. When a PIM requiring 3.3V (such as the PIC18F87J50 FS USB PIM) is plugged in, resistor, R2, located on the PIM alters the feedback circuit of the adjustable linear regulator and configures it to produce 3.3V. ...

... MCLR. It may be used to reset the microcontroller when the PIM is used either stand-alone or while connected to the HPC Explorer board. Pin, RB4 on the PIC18F87J50 microcontroller, is pulled resistor (R26 on the PIM). If push button the PIM, is pressed, it will pull RB4 low. This push button may be used for any general purpose user interfacing purposes. ...

... USB building blocks which have officially gone through the compliance testing process will have a Test ID (TID) number associated with them. Microchip’s USB microcontrollers, such as the PIC18F87J50, have TID numbers associated with them, and these numbers can be found at the USB design center: http://www.microchip.com/usb (click on the “ ...

... However, the pads of U1 have been designed to accommodate any of the products in the PIC18F87J50 family of microcontrollers, both the 80-pin TQFP and 64-pin TQFP. For example, if the PIC18F87J50 is carefully desoldered using hot air, and the pads are cleaned using solder wick possible to install the 64-pin TQFP PIC18F65J50 in its place ...
