STV0680B hardware interfaces
STV0680B + VV6444/6410/6500
22/63
Version 3.4
Table 5 : Timing parameters for SDRAM read/write
4.3.3
SDRAM refresh period
The SDRAM refresh period from STV0680B is guaranteed to be no greater than 15.6
µS during
‘Snapshot’/self-timer/continuous/tethered video modes of operation (i.e. not standby mode). In
standby mode, the SDRAM is set to self-refresh, therefore no refresh from STV0680B takes place.
4.3.4
SDRAM initialisation period
The SDRAM initialisation period is currently set to 981
µS in STV0680B.

USB interface
STV0680B includes a USB Version 1.1 compliant Universal Serial Bus Interface, including a
transceiver. This allows direct connection from STV0680B to a USB connector with minimal
additional hardware (i.e. a small number of passive discretes) - see
Chapter 6
The USB interface interfaces the STV0680B to the USB at full speed 12MHz data rate. Some of the
features are:
q
Compliant with USB protocol revision 1.1.
q
USB protocol handling.
q
USB device state handling.
q
Clock and data recovery from USB.
q
Bit stripping and bit stuffing functions.
q
CRC5 checking, CRC16 generation and checking.
q
Serial to parallel conversion.
q
Single bulk end point.
USB drivers are supplied by ST. For USB timing information, please refer to the USB specification
V1.1.
