content: I have 2 Universal Programmer1. T48 Xgecu2. P4000 PROM ProgrammerMain aim : To read data of 84 pin IC H8/532 HD6475328FIssues :In T48 i don't see the name of IC list thereIn P4000 the PC doesnt read the programmer. It says unknown device in device manager.Can anyone know anything about this issuesAll the images are attached.

content: 1980-90s uC has a mode where the IO port becomes an EPROM compatible pin as it is, so it can be read/written as a normal EPROM.adapter board converts the pins to be EPROM compatible. 27C256 it says.I think you can read it on xGecu or P4000 if you select M27C256 etc..xGecuであればSTmicroのM27C256を選択すれば読み書きできると思います。(OTPなので書き込めませんが)

content: No they are different, i mean some are same some are different.like 21 pin is coonected to 1 BUT 10 is notOH CG/CP are same,OH i guess they are same then.BUT those 28 pins are later change to 32 pins, maybe error is there.

content: if the wiring is different, it is probably an adapter board specifically for the P4000.need to rewire it as shown in the wiring diagram. if you don't mind modifying the adapter board, can cut traces and bodge wires only for the different pins.a-ha!i see that the adapter board has 2 boards.it appears that the upper board converts to 27C256 and the lower board converts to P4000-specific wiring.if you modify the board as the image shows, may can use it.Connect the red wire part,Cut the pins in the white "X" pins.白くバツした4つのピンをカットして、赤くペンした部分を配線すれば、使えると思う。配線しなおしたピンを上側(1ピン)としてxGecuに繋いで、ピンエラーが出ないか確認。

content: Quote from: squadchannel on December 20, 2024, 01:10:33 pmIf we look for FP 80 A, then it is different.BUT CG/ CP pins are matching.Do we need all pins to match or only CG/CP tables is ok?

content: Do you know whats its called the adapter which convert 84 pins to 28 pins.H8/532 CP 84 Pins to HN27C256 28 Pins.The name in both Japanese and English.

content: Don't some chip's have an ID code on them, so if you tell the programmer it's one IC, but the ID doesn't really match, I guess you get this error ?? Are those pins pulled high for $FF FFI also just got a T-48, for some reason, I couldn't use the pinheaders for a 4-wire SPI connection to a common DIP-14 ATtiny44A. It only let me choose the Ziff socket.

content: Maybe is it because i use adapter to convert 84 pin PLCC to 28 pin DIP that's why it say chip error?

content: First of all DS says it compatible with HN27C256 (not M27C256B). If your programmer support this chip - select it. All 27C256 has compatible programming mode, but some differences between them still exists.And second - your programmer try to read ID code from chip. M27C256B support it, but there is no any evidence of supporting ID in HD6475328F datasheet. So just turn off ID verification in T48 (this is a reason for error you got)

content: xvr, yes.ID checks should be disabled. specify HN27C256.But there is no such thing as programming mode in EPROM. It is just a ROM.The only thing that can be said is that the ID is output. Basically, they are compatible with any manufacturer. except that the VPP voltage of early EPROMs is higher.(Why don't you actually try it before asking here)But what is it going to do when it reads from ROM? Backup?most of the NOS in these old microcontrollers are masked or OTP, and even if they are OTP, there shouldn't be that many of them that are unused and nothing has been written to them.Rewritable ones for prototype use are not so common. maybe UV type.

content: QuoteIt is Electrically Programmable ROM, not a just ROM. It could be OTP or UV erasable. And they HAVE slightly different programming algorithms (may be 'mode' is not a exact word, and 'algorithm' will be better).They all programmed by pulses on chip pin, but length and number of pulses are different. All of them can be programed by one long pulse, but manufactures suggest another algorithms.I know this, because a log time ago I took a part in universal Programmer development, and I wrote all these algorithms.As fa as I remember there were 3 basic types of algorithms:Simple. Just write by one long pulseSmart. Each cell in EPROM programmed by series of short pulses, until it became programed. Than another series of pulses with total number 3*<number of pulses in first series> appliedSmart 2. Each cell in EPROM programmed by series of short pulses, until it became programed. Than another one pulse with total length of 3*<number of pulses in first series> appliedAfter this performed verification of EEPROM contents.Each manufacturer also provides its own Vpp, pulse length, maximum number of pulses, Vcc during programming and verification.

content: Yes, you can. But erasing chip to reprogramming it is another story. Ir can't be done by any programmer. If your IC have window you can erase it by UV light. If not - it's OTP chip

content: I would check with DMM to make sure it is wired according to the diagram, make sure the power pins are correct, and read it...less than an hour's work.OPs taken five days so far.prudence, prudence, prudence.....

content: It has taken a lot of time because every time i read data the datas are different.It shows FF only sometimes and it shows data sometimes.I am thinking and worried that past programmar has used some protected bits which cant be read.If thats the case then there is no point of copy to new IC as protected bits cant be seen or copy?Or what shall be next steps?
