Chapter 1. Setting Up the
USB-Blaster Download Cable
Introduction The USB-Blaster™download cable interfaces to a standard USB PC port.
This cable drives configuration data from the PC to the device. Because
design changes are downloaded directly to the device, prototyping is
easy and multiple design iterations can be accomplished in quick
succession.
Device Support
The USB-Blaster download cable allows you to program and configure
Altera®devices. Specifically, you can do the following:
■Download configuration data to FPGA devices:
●Stratix®II, Stratix GX, and Stratix family of devices
●Cyclone™II and Cyclone family of devices
●APEX™II and APEX 20K family of devices
●ACEX®1K devices
●Mercury™devices
●FLEX™10K, FLEX 10KE, and FLEX 10KA family of devices
●Excalibur™devices
■Download configuration data to User Flash Memory (UFM) devices:
●MAX®II family of devices
■Download configuration data to EEPROM-based devices:
●MAX 3000 and MAX 7000 family of devices
■Perform in-system programming of advanced configuration devices:
●EPC2, EPC4, EPC8, EPC16, and EPC1441 devices
■Perform in-system programming of serial configuration devices:
●EPCS1, EPCS4, EPCS16, and EPCS64 devices
In addition, the USB-Blaster download cable supports target systems
using 5.0 V TTL, 3.3 V LVTTL/LVCMOS, and single-ended I/O
standards from 1.5 V to 3.3 V.
Power Requirements
The USB-Blaster download cable requires the following power sources:
■5.0 V from the USB cable
■Between 1.5 V and 5.0 V from the target circuit board
