microEngineering Labs U2 USB Programmer


The new and improved model of the popular melabs USB Programmer now offers even more features than before! More than 300 PIC Microcontrollers are supported! Support for future devices can be added via FLASH firmware updates.

Intelligent voltage regulation allows programming of the new, low-voltage PIC MCUs as well as standard five-volt devices. The U2 USB Programmer is powered by the USB port. No additional external power adapter is needed!

U2 USB Programmer Features:

  • Powered from USB port
  • Fast FULL SPEED USB data transfer
  • HID interface
  • Standard USB cable ("A" male to "B" male)
  • Full featured, command-line operation
  • Automatic Vdd and Vpp adjustment for different PIC MCUs
  • Dual-color indicator shows ready/busy states
  • In-Circuit Serial Programming (ICSP) connector for interface to project board
  • Full featured software included with support for ICSP-capable PIC MCUs
  • Flash firmware easily upgradeable to add support for future devices
  • Compatible with Microchip HEX format files
  • Compatible with all Programming Adapters

Programming Adapters: We offer an extensive line of programming adapters that allow you to program devices in DIP, Surface Mount, and PLCC packages. To find an adapter to fit the part/package that you need to program, see our Programming Adapters section.

In-Circuit Serial Programming: The U2 Programmer is capable of programming PIC MCUs in-circuit. This allows you to solder the chip to your board before you program it, making both development and production more convenient. To use this feature, your target board must have some means of connecting to the 10-pin header on the programmer. More information about ICSP may be found here.

Automated Programming: The melabs Programmer Software can be controlled with command-line switches. This allows you to automate repetitive programming processes for production or development. You can even disable the graphic user interface (GUI) so that options and settings cant be changed accidentally. This also makes it possible to perform multiple programming tasks from a batch file or custom application.

Software: The programmer includes software for Windows 98/Me/NT/2000/XP. This software allows you to control the programmer and set the configuration bits on the PIC. The software may be run as a standalone application or launched from most program editor/IDE packages like MicroCode Studio.

The melabs programmer software is compatible with the standard Microchip HEX format files. Any assembler or compiler for PICmicros can be used to create the program, including MPASM, the CCS C Compiler or the melabs PicBasic Pro Compiler.

The same software that controls the U2 Programmer can be used with all models of our programmers, including EPIC parallel port programmers and melabs Serial Programmer. The software can even control multiple programmers on one computer.

The software allows you to set configuration bits on the PIC with an easy-to-use list of options. Each configuration option is selectable in a drop-down list. Configuration data may be read from a hex file or from a PIC.

The consolidated view-memory window lets you view each section of memory in the PIC with a click.

A formidable list of options allow you to customize the way you interact with the software. You control what areas of the device are erased, programmed, and verified. Save mouse clicks with options like "Disable completion messages" and "Erase before programming".

The programmers firmware can be upgraded electronically with the click of the mouse. You dont have to worry about whether your hardware is compatible when purchasing a software upgrade. Any required firmware changes will be included in the purchased upgrade.

The U2 USB Programmer is now also available as a cased version. Same great funtionality as the standard version but enclosed in a tough plastic case for enhanced durability. Ideal for use in the field!

The U2 USB Programmer is also available in convenient, cost-saving bundles which include a U2 USB Programmer, USB Cable, 8-40 Pin DIP Adapter, Software and Documentation.
See our Programmer Bundles page for more information.

We offer a selection of adapters for various device packages.
