1 INTRODUCTION
The ST7265 MCU supports volume data ex-
change with a host (computer or kiosk) via a full
speed USB interface. The MCU is capable of
handing various transfer protocols, with a particu-
lar emphasis on FLASH media card mass storage
applications.
ST7265 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 card.
