Programming Spec for Altera devices

[sheawh1]

I am looking for the programming specifications for the following Altera devices, wonder if I can get some document on how to read/ write/ erase the chips?

EPM7064LC68-12

EPM7128ELC84-20

EPM7160SLC84-10

EPC1213PC8

EPC1441

Hi there,

All these operation can do in the "programmer", the tools of Quartus. For example, there is the link of usg of programmer of erase flash.

https://www.intel.com/content/www/us/en/docs/programmable/683039/22-3/full-erase-of-flash-memory-sectors.html

Hope this can help u~

Not quite accurate.

True enough for read/write/erase recent versions of the EPCS configuration eprom devices.

But no currently available online versions of Quartus support read or erase of the EPM7K MAX devices.

13.0sp1 and 13.1 support program/verify. Examine/erase are not supported.

The EPC1213 and EPC1441 are small DIP8 one time programmable configuration devices.
They are programmed thru MaxPlusII/QuartusII via the ByteBlaster/USBBlaster cable.
They are NOT JTAG devices. The data sheet does not specify how to write to the devices.

Your referenced EPM7064 and EPM7128E devices are not JTAG reprogrammable, they use the old parallel pin algorithm.
The EPM7160S is a JTAG device and can be programmed via JTAG or the old parallel pin algorithm.
Unfortunately none of the programming algorithms are public knowledge.
Third party programmers like Xeltek or EEtools devices can program these parts, they have signed NDAs to get access to the algorithms.

I suspect even today you would need to justify your need and sign an NDA with Intel to get the algorithm.

Hi there,

Is it useful~

Hi, 

Thanks for asking.  Indeed we are a third party programmer manufacturer and want to support this device by ourselves not by other hardware. 

We do have an NDA with Intel for programming spec,  would there be other contact window for that?

Thanks

Hi there,

That's great, however I just know the tech question.

Please contact the sales in your country, they may have better answer~
