I have successfully programmed a 27c160 with the programmer.īasically you need to program it with a 27c4096 which will program a quarter of the chip at a time, so you need to program it 4 times. Thread Linkįor these chips, a different version may have the same programming algorithm, but need to have more address pins. These chips can use existing algorithms with a little help (address decoder/encoders, programing voltage, etc.)įor programming an old 2732 EPROM on my TL866 I designed a quick&dirty adaptor to apply an external 25V programming voltage. P20 P20 (~OE/~G1) I decided to leave this jumper in since they seemed like the same function. The pins on the AM27S191 and X2816A are the same except for four pins (18,19,20,21).
Then the chip pin can then be routed to a different signal from the TL866 ZIF output.ĥ. Alternatively the jumper can be removed (opened) to by pass normal feed from the TL866. Created a 40-pin ZIF adapter that has jumpers that allow each pin to be jumped and feed directly from the TL866 ZIF socket to the adapters ZIF socked. One of the closest TL866 supported devices is X2816A but it requires rerouting 3 lines.Ĥ. There is no direct support on the MiniPro TL866 for the AM27S191 device.ģ. Procedure To Read AM27S191 (2048X8) PROMS With MiniPro TL866:ġ. ST 27C1000 32-Pin DIP can be programmed as the ST 27C1001 32-Pin DIP if you swap pins 2 and 24.
KM28C16 can be programmed as AT28C16 Thread Link Different Pinoutįor these chips, a different version may have the same programming algorithm, but need to have the pins in a different order. There are some chips that work with minimal fiddling, this is a place to catalogue how to use the tl866 with those chips.įor these chips, just choose a different name (usually a different manufacturer of the same chip) and it will program just fine. The graph shows that only 157 devices are needed to account for 10003 of the 13137 entries. This shows that of the 1044 unique industry part numbers in the MiniPro list of 13137, that only 34 of 1044 unique parts are needed to account for 50% (6579 entries) of MiniPro's 13137 entries. User NateOcean EEVBlog did a interesting overview of the supported chips. List is available on the official website MiniProSupportList.txt. There're currently approximately 13000 supported chips.
