USB Controller 16-Pin QFN

The enCoRe V family of devices are designed to replace multiple traditional full-speed USB microcontroller system components with one, low cost single-chip programmable component. Communication peripherals (I2C/SPI), a fast CPU, Flash program memory, SRAM data memory, and configurable I/O are included in a range of convenient pinouts. The architecture for this device family, as illustrated in the enCoRe V Block Diagram on page 1, consists of two main areas: the CPU core and the system resources. Depending on the enCoRe V package, up to 36 GPIO are also included. This product is an enhanced version of Cypress’s successful full speed-USB peripheral controllers. Enhancements include faster CPU at lower voltage operation, lower current consumption, twice the RAM and Flash, hot-swappable I/Os, I2C hardware address recognition, new very low current sleep mode, and new package options.
