jdm 93c46

Hi,
i have an JDP programmer. I Can perfectly program 93C46 and others microwire memories but the 93C86 doesn´t works.
Anybody knows why??

Thank you!

Please see the text below . I extracted it from winpic800 . Indicate the suffix letter whether 93C86A or 93C86B follow the datasheet if it is B version as regards setting the ORG pin.

Description:

The Microchip Technology Inc. 93XX86A/B/C devices are 16K bit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93XX86C are dependent upon external logic levels driving the ORG pin to set word size. In the SOT-23 package, the 93XX86A devices provide dedicated 8-bit memory organization, while the 93XX86B devices provide dedicated 16-bit memory organization. A Program Enable (PE) pin allows the user to write-protect the entire memory array. Advanced CMOS technology makes these devices ideal for low-power, nonvolatile memory applications.

The entire 93XX Series is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, 6-lead SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is available.
