content: I was checking for updated software for my XGecu T56 programmer today and noticed they’re now selling a new T76 model!In addition to supporting 76-pin chips, it looks like they’ve finally moved away from the antiquated USB-B connector to a USB-C with USB 3 speeds (140MB/s). They have added some new gold 2mm ground contacts, I presume will be used by some future adapters. The website claims several other improvements. Has anyone gotten their hands on the new model yet? I ordered one for under 150 American greenbacks, but since it's Chinese New Year, it will probably take a while for them to ship it to me.The info about it is on their homepagehttp://www.xgecu.com/en/I don't see any reviews by Dave or anyone else on youtube. Hopefully it's not vaporware—I would have expected them to send him one for promotional purposes before they even released the product.

content: I guess the xgecu programmers must not be as popular as I thought they were. My new t76 has been sitting in some customs warehouse in new yuck for almost 4 days now. Frustrating.

content: T48 and predecessor TL866A have been good. T76 should be very good - let us know how it goes.

content: @kelemvor Good news. Ordered one. The T56 has become my favorite programmer. Way faster than RT809H and my Batronix BX48II. Maybe i can replace it with the T76.

content: My new T76 arrived yesterday. I had time to have a look inside for comparison.Enclosure size T56: 130 x 86 x 37 (29 without Socket) mm,USB-B Port, 5V DC 5,5x2,3 mm barrel jack, On/Off switch, 8-Pin ISP connector, 48-Pin Socket.Enclosure size T76: 117,5 x 71 x 33,5 (28,5 without Socket) mm.USB-C 3.0 Port, 5V DC 3,9x1,6mm barrel jack (smaller), push button latching (smaller), 28-Pin connector (2 row, 14 Pin, 2mm pitch), 48-Pin Socketand 6 unique Pins surrounding the Socket.Five of the Pins are connected to Ground (USB-C - and USB-C shield).The middle Pin on the side with the DC barrel jack might be +. It has 38,83 kOhm (black probe on the Pin, red probe in GND) or 1,34 MOhm (red probe on the Pin, black probe on GND) resistance.

content: Hi Jim,Would you mind sharing which country you're in? I’m in the US and am still waiting on my order. It's becoming a bit frustrating, though thankfully I don’t have a project that depends on it.Have you had the chance to use it yet? I'm curious to know if you find it significantly faster than the T56.Thanks!

content: @kelemvor This time aliexpress was realy quick sending me the T76 to Germany. Ordered on Feb. 12, received on Feb. 18.I have an idea why you are waiting for stuff from China.Actually i don't have a project with large enough data to measure significant time difference. Tomorrow i can check what memory chips i have in my shelf.

content: The move from AMD Xilinx Spartan6 to Shanghai Anlogic Eagle 4 is interesting. The list price on the Eagle chip ($12.50 USD alibaba) is about ⅓ the price of the Spartan 6 ($36.82 USD digikey).

content: There is a new BGA64 adapter available supporting the six unique pins surrounding the socket. They write it replaces 3 different adapters needed for the older programmers.https://aliexpress.com/item/1005008310955391.htmlThe T76 supports all the chips the T56 supports, Microcontrollers but so far, no hint about embedded controlers (SuperIO chips). Support of EC chips would be great.

content: @kelemvorToday i tested a 29GL032N90TFI04 @TSOP48 on both devices, same USB-C cable, an additional adapter on the T56 to match the USB-B port.I used a 4 MB file. The T76 is falsly defined as T56 in the log files.T76, APP Version : 12.79 Model : T56Programming FLASH ...Finished. Time: 8.094 sReading FLASH ...Finished. Time: 0.813 sErase ...Finished. Time: 14.843 sT56, APP Version : 12.78 Model : T56Programming FLASH ...Succeeded. Time : 7391msReading FLASH ...Succeeded. Time : 922msErase ...Succeeded. Time : 14.281 SNo time saving with the new T76 on this chip.I received the holy grail of the bga adapters. It should replace the different BGA adapters needed on the T56.The six special pins are pogo pins. They look a bit fragile. I printed a box for it to prevent damage.There is a downside. I tought i could use the TSOP32/40/48/56 adapter from T56 up to TSOP48 devices on the T76. It's not working because the pins on this adapter start on the separate 8-pin interface. Same with the TSOP adapter for the RT809H. It doesn't even fit to the ZIF socket and the pins also start on the separate pin socket, not the ZIF socket.For the T76 there is a new ZIF adapter, the T76_F56_05-002 V1.0. My universal TSOP48 adapter did the job. I ordered the new ZIF adapter.Logfiles and some images are attached.

content: The T76_F56 adapter is definitelly not the holy grail. I ripped off a THGBMHG9C4LBAIR 32GB 11.5x13 mm emmc chip from an old Sony Xperia phone to perform another speed test for reading/writing. For this device i need this new T76 BGA153/169 adapterhttps://de.aliexpress.com/item/1005008461218365.htmlI didn't notice this adapter 2 weeks ago when i ordered the T76_F56 adapter.Another week waiting for deliveryThe IFIX V2.5 adapters i use on the RT809H also don't work for BGA

content: well see how they do with time, since they claim the t76 will do the t48 and 56 ... for sure new adapters are needed in some casesno fan of the 6x pogo pins .... i was about to pull the trigger, but ill wait a bit, other things to do and buy lollthey do say the SW will matureonce again loll no absolute programmer

content: It finally arrived!Unfortunately, the XGECU store only offers government mail options (e.g., USPS, China Post, or whatever your local postal service is called). My first package reached the USA, but US Customs either "lost" it—or perhaps a customs worker ended up with a new toy at home. Who knows?I contacted the company, and to my surprise, the representative I reached in China spoke flawless English. After some back-and-forth, I convinced them to send a replacement via their local FedEx. It shipped out on March 3rd and arrived at my doorstep today, May 5th—pretty impressive!They even included all the old adapters with the replacement. I already own these for my T56, but now if I decide to sell or gift my older unit, it’ll come with some handy accessories.One minor gripe: attaching the TSOP56 adapter to the unit was a bit tricky. The ZIF lever bumps into the adapter’s edge, and you have to remove the ribbon cable entirely since its connector blocks the lever from opening fully. It feels like a design oversight—reorienting the socket could’ve avoided this hassle.I could’ve ordered from a third party like Amazon for simpler logistics, but with Bezos charging 200% of MSRP, that’s just not reasonable.

content: Quote from: JimKnopf on March 02, 2025, 07:17:55 pmUgh, I missed that detail too! XGECU’s store is sold out of these, so I ended up ordering from AliExpress instead. About your link—it looks like that seller only includes three limit frames, whereas the manufacturer typically provides five. Hopefully, the missing ones won’t be frames you’ll need anytime soon.I also grabbed the BGA64 adapter. I’d hoped to find a kit with all the adapters XGECU makes, but the two BGA adapters weren’t part of the package.Now I’m on the hunt for a decent case to safely store my programmers and all these adapters.

content: I now have all available adapters for the T76. I had to read the THGBMHG8C4LBAIR with the T56 again because the one that i desoldered from an old phone was no longer working. There was another reason. When i first tried to read the THGBMHG8C4LBAIR with the new Socket in the T76, there was a message that my USB Cable was not good enough.Quote(Edit: I picked the wrong Chip when i took the screenshot, the msg. was the same with the correct Chip)I ordered some new THGBMHG8C4LBAIR for testing which arrived this week. I used a USB 4 40Gbps Cable for reading on both devices.For the T56 i had to use an Adapter because of the old style USB connector.https://de.aliexpress.com/item/1005006067156104.html?gatewayAdapt=glo2deuWith this cable, the readings with T76 was significant faster than on the T56.Reading THGBMHG8C4LBAIR 1bitT56 Reading User Area : Succeeded.

content: Aha! Good catch. I plugged in the Apple USB-C cable that I usually use, and sure enough, it was detecting as USB 2.0. I have some ultra-short USB-C/Thunderbolt cables that came with some NVMe-to-thumb-drive adapters I own, and those worked at 5GHz for the T76.I guess that's something I'll have to keep in mind. I wrongly assumed that a cable was just a cable. It's an odd situation with the USB Type-C connector, which is used for a variety of protocols.

content: Just got mine, seems pretty good so far. I like the compact dimensions. As a Linux user I have to run the software in a VM - couldn't get it to work in an XP guest under KVM due to some USB issue, but it works fine in XP under VirtualBox with a USB2 cable. Not sure if there's support for VBox USB3 in XP Guest Additions, but speed doesn't matter much to me. Tried with a few Atmel MCUs which could be read and written without issue, and tested some 74-series logic with the included logic tester. Sweet.Went shopping for a storage case and came back with a small first-aid kitDonated the contents and tried to remove the "First Aid Kit" printing with acetone, which wasalmostsuccessful. It's the perfect case though; quite sturdy and just large enough to hold the T76 and the adapters (9 in total) and cables with room left over for some future additions. Love the red colour. Thought I'd share the tip!
