DebugJet Hardware Specifications

The table below specifies DebugJet technical specification and features.

DebugJet Hardware Specification
Feature Specification

Host interface

USB 2.0 and Fast Ethernet interface.

Host interface speed

480Mb/S USB port and 10/100/1000Mb/S Ethernet.

Host Ethernet protocols

DebugJet supports TCP/IP, FTP and Telnet Ethernet protocols.

Ethernet boot protocols

BOOTP, DHCP and static IP address are supported. Protocol is user selectable.

Target hardware interface

DebugJet supports JTAG as well as FLASH Memory emulation using PROMJet.

Debug port voltage

JTAG interface and Input/Output ports support target voltage between 1.5 and 3.3V.

Aux I/O Port

User can optionally read or set target hardware via a 4-bit Input and a 4-bit output port on the JTAG connector.

Trigger Input

The trigger input line can be optionally used to start/stop the target processor.

Trigger Output

DebugJet can optionally set the trigger-out line when the target processor stops/starts executing code.

Serial Port

Serial Port is used for optional System setup if USB or Ethernet are not available. User can also use it via an TCP/IP telnet session for an Ethernet to serial port conversion.

GNU Debugger support

GDB native debug protocol is supported.

Flash Memory Programming

DebugJet supports Flash programming via the JTAG interface. Support is available for the AMD, Intel and CFI Flash memory chips.

FPGA/CPLD Programming

DebugJet supports programming of FPGA and CPLD chips from Altera, Lattice and Xilinx.

Trace Support

DebugJet supports Trace collection via TraceJet module.

Flash Emulation (optional)

SPI, LPC as well as 8/16/32 Bit Parallel Flash emulation are integrated in the JTAG debug protocol. Support is also added for code/data image downloading via FLASH socket.

Memory On-The-Fly Access (optional)

DebugJet integrates PROMJet ability to access target memory without stopping target processor into the JTAG debug protocol. Supports debugger data viewing and editing without stopping target CPU as well as data communication channels via FLASH memory interface.


DebugJet is upgradeable to the latest firmware revision via USB or Ethernet interface.


32 bit RISC processor with 32MB SDRAM, 2MB Flash and FPGA for JTAG interface logic.


DebugJet ships complete with software, manual, cables and connectors.

Power supply

DebugJet uses a world power supply (90~240VAC).

Physical dimensions

4.0" x 2.4" x 1.0" (101 x 61 x 25 mm).
