Configuring
Using the
MicroBlaster
Driver
The MicroBlaster
TM
software driver allows you to configure Altera
devices in an embedded environment using PS or FPP mode. The
MicroBlaster software driver supports a Raw Binary File (.rbf)
programming input file. The source code is developed for the Windows
NT operating system, although you can customize it to run on other
operating systems. For more information on the MicroBlaster software
driver, go to the Altera web site (www.altera.com).

Configuration
Pins
The following tables describe the connections and functionality of all the
configuration related pins on the Stratix or Stratix GX device. Table 11–15
describes the dedicated configuration pins, which are required to be
connected properly on your board for successful configuration. Some of
these pins may not be required for your configuration schemes.

Pin Type Description
VCCSEL
N/A All Input Dedicated input that selects which input buffer
is used on the configuration input pins;
nCONFIG, DCLK, RUnLU, nCE, nWS, nRS, CS,
nCS and CLKUSR.
The
VCCSEL input buffer is powered by
V
CCINT
and has an internal 2.5 kΩ pull-down
resistor that is always active.
A logic high (1.5-V, 1.8-V, 2.5-V, 3.3-V) selects
the 1.8-V/1.5-V input buffer, and a logic low
selects the 3.3-V/2.5-V input buffer. See the
“V
CCSEL
Pins” section for more details.
PORSEL
N/A All Input Dedicated input which selects between a POR
time of 2 ms or 100 ms. A logic high (1.5-V, 1.8-
V, 2.5-V, 3.3-V) selects a POR time of about 2
ms and a logic low selects POR time of about
100 ms.
The
PORSEL input buffer is powered by
V
CCINT
and has an internal 2.5 kΩ pull-down
resistor that is always active.
