STMicroelectronics recently introduced an innovative bi-core controller chip for the fast-growing USB Flash Drive market. The ST72681 USB 2.0 Flash Drive Controller uses an advanced architecture based on an ST7 8-bit microcontroller tightly coupled with a fast, 16-bit, one-cycle-per-instruction input/output processor, which is dedicated to the Flash interface, and a Reed-Solomon error-correction processor for multilevel cell NAND Flash devices.
The ST72681 Flash drive controller is a complete low-cost turnkey solution for the interface between the USB port and the Flash memory, and is supported by a comprehensive set of tools for production including Vendor ID, Product ID, and serial-number customisation, as well as LED setting, formatting, boot capability, and public/private zone partitioning.
With exceptionally low power consumption - 290 μA in suspend mode and 50 mA operating supply current - the ST72681 comes in a small footprint TQFP48 package and in die form.
