22.0
This section describes the details of the USB
peripheral. Because of the very specific nature of the
module, knowledge of USB is expected. Some
high-level USB information is provided in Section 22.9
“Overview of USB” only for application design refer-
ence. Designers are encouraged to refer to the official
specification published by the USB Implementers
Forum (USB-IF) for the latest information. USB Speci-
fication Revision 2.0 is the most current specification at
the time of publication of this document.

22.1
PIC18F87J10 family devices contain a full-speed and
low-speed, compatible USB Serial Interface Engine
(SIE) that allows fast communication between any USB
host and the PIC
interfaced directly to the USB, utilizing the internal
transceiver.
Some special hardware features have been included to
improve performance. Dual access port memory in the
device’s data memory space (USB RAM) has been
supplied to share direct memory access between the
microcontroller core and the SIE. Buffer descriptors are
also provided, allowing users to freely program end-
point memory usage within the USB RAM space.
Figure 22-1 presents a general overview of the USB
peripheral and its features.
