New generation of Windows 98/Me/NT/2000/XP/2003/XPx64/Vista based ELNEC specialized programmers. Programmer is capable to support all currently available microcontrollers of the MCS51 series (up to 40 pins) and the AVR microcontrollers (8-40 pins) using parallel and serial algorithms. T51prog2 has been developed in close cooperation with Atmel W&M., therefore programmers hardware is focused to support all current and future microcontrollers of Atmel W&M MCS51 family.

T51prog2 is a small, very fast and powerful portable programmer for MCS51 series and Atmel AVR microcontrollers. T51prog also programs serial EEPROM with IIC (24Cxx), Microwire (93Cxx) and SPI (25Cxx) interface types. Using build-in in-circuit serial programming (ISP) connector programmer is able to program MCS51 family microcontrollers and Atmel AVR microcontrollers using serial algorithms.

Provides very competitive price with excellent hardware design for reliable programming. Nice value for money in this class.

Very fast programming due to high-speed FPGA driven hardware and support of high-speed USB port. Surely faster than competitors in this category.

T51prog interfaces with the IBM PC compatible or higher, portable or desktop personal computers through USB port.

T51prog2 is easy upgradeable to SmartProg2 programmer using upgrade kit Xprog2 to SmartProg2 ( 60-0048).


40 powerful TTL pindrivers provide H/L/pull_up/pull_down and read capability for each pin of socket. Advanced pindrivers incorporate high-quality high-speed circuitry to deliver signals without overshoot or ground bounce for all supported devices. Pin drivers operate down to 1.8V so you be ready to program the full range of todays advanced low-voltage devices.

The programmer performs device insertion test (wrong device position in socket) and contact check (poor contact pin-to-socket) before it programs each device. These capabilities, supported by signature-byte check help prevent chip damage due to operator error.

T51prog2 programmer performs programming verification at the marginal level of supply voltage, which, obviously, improves programming yield, and guarantees long data retention.

Various socket converters are available to handle device in PLCC, SOIC, SSOP, TSSOP, TQFP, QFN (MLF) and other packages.


Programmer is driven by an easy-to-use control program with pull-down menus, hot keys and on-line help. Selecting of device is performed by its class, by manufacturer or simply by typing a fragment of vendor name and/or part number.

Standard device-related commands (read, blank check, program, verify, erase) are enhanced by some test functions (insertion test, signature-byte check), and some special functions (autoincrement).

All known data formats are supported. Automatic file format detection and conversion during loading of file.

The rich-featured autoincrement function enables one to assign individual serial numbers to each programmed device - or simply increments a serial number, or the function enables one to read serial numbers or any programmed device identification signatures from a file.

The software also provide a many information about programmed device. As a special, the drawing of all available packages are provided. The software provide also explanation of chip labelling (the meaning of prefixes and suffixes at the chips) for each supported chip.

The software provide a full information for ISP implementation: Description of ISP connector pins for currently selected chip, recommended target design around in-circuit programmed chip and other necessary information.


It is important to remember that support of new devices with compatible GND/VCC/VPP pinout requires only a software update due to the T51prog2 hardware. With our prompt service you can have a new device added to the list of supported devices within hours! Free software updates are available by download from our WEB site. Keep-Current and AlgOR services, our next step towards customer satisfaction.

Keep-Current service means, that ELNEC ships the latest version of programmer software and updated user documentation (Keep-Current package) to customer . The Keep-Current service is your hassle-free guarantee that you are achieving the highest quality programming on ELNEC programmers, at minimal cost.

AlgOR (Algorithm On Request) service gives the user a tool to influence to amount and types of programmed devices as needed.
