PREPROM-02aLV is a small and powerful EPROM, EEPROM, Flash EPROM and serial EEPROM programmer and static RAM tester, designed for professional mobile applications. In addition, PREPROM-02aLV programmer with auxiliary modules support also microprocessors (MCS48, MCS51, PIC, AVR), GALs, etc. Generators for supply voltage and programming voltage are digitally controlled and level of H can be limited, therefore programmer can work with 'true LV' device too - from 2V. Performance, dimensions and speed of PREPROM-02aLV can be used both in maintenance and in production. Following high reliability of Elnec's programmers, 3 years warranty is provided for PREPROM-02aLV.

PREPROM-02aLV interfaces with the IBM PC 486 compatible or higher, portable or desktop personal computers. Programmers allows you to directly connect to your PC through any standard parallel (printer) port - no special interface card is needed.

Built-in protection circuits eliminate damage of programmed device due to mains supply error, communication error or if PC is frozen. Programmer's hardware afford enough resources for self-test (using diagnostic POD), that control program is any time be able to check pindrivers, presence and level of all voltages, check the timing and communication between programmer and PC.

A programming verification is performed by the programmer at the marginal level of VCCP, which, obviously, improves programming yield, and guarantees long data retention.

The advantage of PREPROM-02aLV is its easy-to-use comfortable software with pull-down menu, hot keys and on-line help. You can select device by classes, by manufacturers or simply type device vendor's name and part number. The standard device operation functions (read, blank check, program, verify) have been completed with some test functions (illegal bit test, insertion test). The program facilitates the use of the buffer and files, including automatic file format detection and conversion.

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 Autoincrement function of PREPROM-02aLV enables one to assign individual serial numbers to each programmed device. This function simply increments a serial number in the buffer each time a new device is inserted. Furthermore, the function enables an operator to read serial numbers and/or any programmed device identification from a file.

Free software updates are available by download

News in the customer support are Keep-Current and AlgOR services.

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

  • AlgOR (Algorithm On Request) service give to the user tool, with which can influence on amount and types programmed devices as need.

The PREPROM-02aLV can make for use of DIL to PLCC, SOIC and TSOP socket converters.

Taking into consideration the PREPROM-02aLV programmer design, protective circuits, and the components used, the manufacturer is able to provide a three-year warranty on parts and labor for the programmer (limited 25,000-cycle warranty on the ZIF socket).


Socket, pin driver, DAC

  • 32-pin DIL ZIF (Zero Insertion Force) socket accepts both 300/600 mil devices up to 32-pin
