Features

SIMEPROM-02aLV is an EPROM simulator, designed for the development workplaces, where are using EPROMs or PROMs. SIMEPROM-02aLV application is in the cases, where is emulator's use ineffective or impossible. Typical applications example of simulator EPROM are low-cost microprocessors system debugging, character generator in videocards/monitors tuning, etc. Special desirable is use of SIMEPROM-02aLV in target systems with + pole grounded (e.g. some telephone exchange) or in cases, when is needed galvanic isolation between PC and target system. SIMEPROM-02aLV can replace EPROM from 2716 to 27040 with the access time above 85 ns. Because output buffer of SIMEPROM-02aLV is powered from target system, there is possible to perform RESET of the target system by its power-off and power-on without problems.

Because simulator are in generally susceptible to damage by ESD (electrostatic discharge), there was developed and build-in into SIMEPROM-02aLV special protection circuit without influence to parameters of simulator. This mean, that simulator SIMEPROM-02aLV is protected either against electrostatic discharge (ESD) and against balancing current that might flow between emulator and target systems.

Quality of SIMEPROM-02aLV and negligible sales returns allows afford nearly lifetime - 3 years - guarantee for it.

Since SIMEPROM-02aLV simulator contains CMOS RAMs, whose contents can be easily changed anytime, it can replace obsolete debugging cycle:
  • switching off the target system
  • removing the EPROM from the socket
  • EPROM erasing
  • EPROM programming
  • inserting EPROM into the socket
  • switching on the target system
    (about 20 minutes)
with much simple procedure:
  • SIMEPROM-02aLV re-downloading
    (about 25 seconds)
In addition, the SIMEPROM-02aLV enables the user forced the RESET signal on a device under development. Thus, a software can be debugged without handling the device.

SIMEPROM-02aLV interfaces with the IBM PC, XT to Pentium Pro, portable or desktop personal computers. Simulators allow you to directly connect to your PC through any standard parallel printer port or through standard (RS232) serial port. In case connection through serial port, SIMEPROM-02aLV is optically isolated from target systems. Using a Y-cable they are possible to connect two SIMEPROM-02aLV simulators on the same parallel port. Generally, on the one PC, it can be connected four SIMEPROM-02aLV simulators.

The SIMEPROM-02aLV simulator is controlled from the PC by the control program, which is common for all of the ELNEC's EPROM simulators. It is easy-to-use nice software with pull-down menu, hot keys and on-line help. The control program find himself type and port of connected simulator. Thus, it's possible connect all types of ELNEC's simulators on the same computer at the same time. User can do:

  • all necessary functions with simulator (download, RESET control)
  • with buffer (view, edit, fill, copy, swap, checksum, print)
  • read/write buffer in binary or wide range of HEX formats.
Before exit of program, it can save all of the configuration for next use.

There is a BAT file version of control program, which can download of simulator content and can change the RESET status. For DOS operating system is available resident version of control program too.

DOS-Software download

There is available appropriate package convertor PLCC32/DIL32 for work with EPROM in PLCC32.
