EEPROM programmer for NEC processor for Mercedes – Benz keys (programmer for “small fishes”)



Functions

The device meaned for erasing and EEPROM programming of NEC processors, which installed into Mercedes keys since 2000. To be programmed the processor should be soldered out from a key and installed to the device board.

The implemented functions

The software of the device has a module structure. The are 3 modules are available at the moment:
• Programmer for EEPROM processor;
• Module of key diagnostics by IK;
• Module for work with latches (ESL).

There are 2 modules in a checkout stage:
• CAN protocol analyzer;
• K-line protocol analyzer.

Lets view some modules in details.

EEPROM programmer

For programming or erasing EEPROM processor must be soldered out from a key and soldered in to module of programmer extension. In programmer software choose “NEC Programmer” module.

*Serial – Keyset ID, Static Code – Password

The following functions are available:
- test of processor;
- recording prepared data into EEPROM;
- EEPROM erasing and preparing the key to the following programming through IK port (after soldering in process into the key);
- Recording data to the key through IK (the processor should be prepared in advance).

We glad to note following features of the programmer:
- time of programming is never come up more the 15 seconds (!);
- it is a possible to set limit for a quantity of key abrasions. On reaching of given limit the car stops recognize the key. The key efficiency can be restored by programmer through IK port.

The module for work with a key through IK

The module mean for keys diagnostics. The programmer supports both NEC and Motorola processors (for oldest models).

Besides the module allows to reset all limits for key abrasions amount (if there were set any).
