1 INTRODUCTION

The ST7265x MCU supports volume data ex-

change with a host (computer or kiosk) via a full

speed USB interface. The MCU is capable of han-

dling various transfer protocols, with a particular

emphasis on mass storage applications.

ST7265x is compliant with the USB Mass Storage

Class specifications, and supports related proto-

cols such as BOT (Bulk Only Transfer) and CBI

(Control, Bulk, Interrupt).

It is based on the ST7 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 trans-

ceivers.

– 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 re-

quired 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 serv-

iced before the DTC.

– A FLASH Supply Block able to provide program-

mable supply voltage and I/O electrical levels to

the FLASH media.
