Description

The ST72651 MCU supports volume data exchange with a host (computer or kiosk) via a full speed USB interface. The MCU is capable of handling various transfer protocols, with a particular emphasis on mass storage applications.ST7265x is compliant with the USB Mass Storage Class specifications, and supports related protocols such as BOT (Bulk Only Transfer) and CBI (Control, Bulk, Interrupt).It is based on the ST72651 standard 8-bit core, with specific peripherals for managing USB full speed data transfer between the host and most types of FLASH media card:

A full speed USB interface with Serial Interface Engine, and on-chip 3.3V regulator and transceivers.
A dedicated 24 MHz Data Buffer Manager state machine for handling 512-byte data blocks (this size corresponds to a sector both on computers and FLASH media cards).
A Data Transfer Coprocessor (DTC), able to handle fast data transfer with external devices. This DTC also computes the CRC or ECC required to handle Mass storage media.
An Arbitration block gives the ST7 core priority over the USB and DTC when accessing the Data Buffer. In USB mode, the USB interface is serviced before the DTC.
A FLASH Supply Block able to provide programmable supply voltage and I/O electrical levels to the FLASH media.
