Having sold hundreds of millions of units, the Cypress enCoRe low-speed USB microcontroller family is the most successful USB device in the industry, but it has not seen an update since its introduction in 2000. In order to keep up with the demands for increasing product functionality and decreasing system cost, Cypress has released the enCoRe II. This Application Note is targeted at developers who are familiar with the enCoRe devices, and who wish to migrate to the next generation enCoRe II. This highlights the differences between the products that require attention during the migration, and also provides guidance on how to use some of the enCoRe II features. Although it discusses some hardware issues, its emphasis is on firmware.
