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 withthe 38000, 7200, 7400, and the 7500 series, and pro-vides many performance enhancements to the instruction set.

This 7640 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.
