SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
1.1 DESCRIPTION
The 7640 group, an enhanced family of CMOS 8-bit
microcontrollers, offers high-speed operation, large
internal-memory options, and a wide variety of stan-
dard peripherals. The series is code compatible with
the 38000, 7200, 7400, and the 7500 series, and pro-
vides many performance enhancements to the
instruction set.
This device is a single chip PC peripheral microcon-
troller based on the Universal Serial Bus (USB)
Version 1.1 specification. This device provides data
exchange between a USB-equipped host computer
and PC peripherals such as telephones, audio sys-
tems and digital cameras. See Figure 1.1 for a pin
layout diagram. See Figure 1.2 for the functional
block diagram.
