|

I got more nice 68k processors and interesting ASIC with still unknown function, so I took more die shots:
Motorola 68HC000 microprocessor (MC68HC000RC10):

Motorola 68332 32-bit microcontroller with CPU32 core (XC68332FE):

Motorola/Codex ASIC marked H04NK4 on package and SCU42580 on die:
Original resolution: https://upload.wikimedia.org/wikipedia/commons/4/44/Motorola_Codex_H04NK4_die.JPG
Thank You very much to aberco for finding H04NK4, CPUShack for 68340 and Bator for 68HC000! I was lucky enough to find ceramic 68332 in scrap pile at university.
I hope you enjoy these and like to see dies with CPU32 core. 68332 is early 1.0 micron one (0C53T mask and 9033 datecode) and 68340 is late 0.65 micron version (2G67F mask and 9636 datecode), so you can also compare different processes there. 68340 die is only 6 mm high, so I'm already losing sharpness there but getting more colorful pic instead. Looks like Hitachi and Motorola 68HC000 are very similar indeed, but at least I got different colors and details due to different processes.
Do you have any information about H04NK4 in 34 mm CLCC package? Looks like there's some of them around and also ones marked SC42580Z, but I'd like to know what this interesting CPU-like die does and where it was used. |

|
|
Here are some interesting different 16-bit x86 CPU dies for you:
Unknown AMD die with 80C186 or 80C188 microprocessor core, 79930A die number and 1995 copyright:
Original resolution: https://upload.wikimedia.org/wikipedia/commons/d/d9/AMD_80C186_SoC_die.JPG
Intel 80C186XL (R80C186XL12):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/b/b0/Intel_80C186XL_die.JPG
Intel 80286 early version in CPGA package without any markings on top but with 8447 datecode and Italy on lid.
Original resolution: https://upload.wikimedia.org/wikipedia/commons/5/54/Intel_80286_early_die.JPG
NEC V53 (D70236R-16):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/1/1e/NEC_V53_die.JPG
Thank You a lot to CPUShack for V53 and unmarked mystery 80286, to kaijusears for AMD wafer and to Vegeta for 80C186XL!
I hope you like looking at V53 and comparing these to ones I've released earlier! Interestingly 80C186XL die has 80C186EA markings and those datasheets also have similar die pics, so I hope you enjoy comparing this to my 80C186EB die shot with some common blocks. Looks like there's CPU core on the right, bus in the middle and other blocks on the left that are different in different versions. That mystery 80286 is also interesting because there's some differences compared to my other die shots. Those areas are more simple like in Intel's die shot, so this one seems to be early version, maybe without fast reset function. Unfortunately, I don't know what that AMD die on wafer is because I don't understand AMD die markings. Maybe we should try unpacking some AMD devices with 80C186/80C188 core and try to find similar die. |

Oh but we do 
The AMD is a AM79C930 PCnet-Mobile
Single Chip Wireless LAN Media Access Controller
The MAC control unit in it is based on a 80188

Thanks for the identification! I updated description but I don't know how to fix filename without reuploading.
Here are die shots of two hopefully interesting vintage 8-bit CPUs and one that wasn't after all:
National Semiconductor SC/MP-2 (INS8060D, ISP-8A/600D):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/1/1f/NS_SC-MP-2_die.JPG
Signetics 2650A (2650AI):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/2/29/Signetics_2650A_die.JPG
Synertek 2650-P-02 that was hand remarked as 2650-P3:
Original resolution: https://upload.wikimedia.org/wikipedia/commons/2/2c/Synertek_2650-P-02_die.JPG
Thank You a lot to lhf_james for SC/MP-2, to isa-d for Signetics and to CPUShack for Synertek! I was lucky with the Signetics because it had lid already partly loose when I got it. Thus, it was easy to open without heating and a good chip for die shot.
I hope you enjoy these although I can't get best sharpness and colors for small old dies that easily look messy. I originally bought Synetek to get die shot of 2650 CPU at low price, but it had a surprise inside. You can see that it doesn't really look like CPU, so I needed Signetics one also after all. Thus, looks like either Synertek ones aren't CPUs or then I just got some fake chip. You can see this chip at CPUShack's sale http://www.cpu-world.com/forum/viewtopic.php?t=25682. Does anyone have any information about these Synertek chips like possible function or identification based on die shot? |

CPUShack found three Data General microEclipse chips in bad condition and sent them me to let us see their dies:
Data General microEclipse microprocessor with F AP 02 markings and 8702 datecode:
Original resolution: https://upload.wikimedia.org/wikipedia/commons/b/b9/DGC_microEclipse_F_AP_02_die.JPG
Data General microEclipse microprocessor with F AP 03 markings and 8723 datecode:

Data General chip in microEclipse chipset with C 01 markings and 8437 datecode:
Original resolution: https://upload.wikimedia.org/wikipedia/commons/b/bc/DGC_microEclipse_C_01_die.JPG
Thank You a lot to CPUShack for letting me take die shots of these interesting chips! I got two similar CPU chips and one other chips in similar CDIP48 package with still unknown function, but other three shorter DIPs are still missing from the chipset. I hope you enjoy looking at these uncommon dies and wondering what that unknown chip could do. Please let me know if you have some information about microEclipse chips or even function of C 01 chip.
I hope to get missing members of this chipset to understand it better. I've also seen pics of two CPU dies without yellow coating that caused low contrast for my pics and loss of many details. Thus, earlier CPU die would be useful if you want to see contrast and details similar to C 01 die. These chips have lids just glued on the ceramics, so it's easy to open them without damage and glue lids back on after taking die shot. |

Here are some die shots of hopefully interesting random CPUs and FPUs:
AMD K5 PR100 (AMD-K5-PR100ABR rev F):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/3/35/AMD_K5_PR100_die.JPG
Intel 80960JA (A80960JA25):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/4/4d/Intel_80960JA_die.jpg
Texas Instruments TMS34082A floating point coprocessor (TMS34082AGC-40) for TMS34020A graphics processor:
Original resolution: https://upload.wikimedia.org/wikipedia/commons/9/92/TI_TMS34082A_die.jpg
Thank You a lot to Demotronic for selling me A80960JA and TMS34082A that I've been trying hard to get for too long! Thank You very much to Malyshh for selling inexpensive K5 rev F to allow comparison between revisions!
I hope you enjoy seeing 80960JA die after way too long wait! It has been hiding unfortunately long because I couldn't find any ceramic version earlier, but luckily it looks very nice. I also bought A80960JD50, but it's also rev A2 and die has 80960JX, so I'd expect both dies to be similar. Thus, I'd rather let some collector buy my A80960JD50 unopened.
I hope you have some fun comparing other two to similar dies I've released earlier. Looking at differences in K5 versions should be interesting, and TMS34082A interestingly has similar FPU components as TMS390C602 SPARC FPU. Why not reuse existing blocks in both floating-point processors. |

I've been working on many die shots of different chips in NS32k family, and I finally finished all of them:
National Semiconductor 32C016 microprocessor (NS32C016D-10):

National Semiconductor 32081 floating point unit (NS32081D-15) with late smaller die:

National Semiconductor 32203 direct memory access controller (NS32203D-10):
Original resolution: https://upload.wikimedia.org/wikipedia/commons/2/26/NS_NS32203_die.jpg
Thank You very much to Udo Möller http://cpu-ns32k.net/ for letting me open these his NS32k chips from Demotronic for die shots! I hope you enjoy looking at details of these dies and have some fun comparing different CPU and FPU versions!
I tried different lighting options with 32C016 and don't know which of them is better. One has more colorful top metal wiring, one has nice shiny datapath details and one has nice ROM, so I'll let you choose your favorite.
Late 32081 die is a bit too small for best resolution after two die shrinks, but hopefully it's interesting to see how die got smaller, faster and more colorful with three different NMOS processes. Looks like first NMOS process gives yellow die shots with only white shine in wiring, and third NMOS process has very shiny lower layers under top metal, so identifying manufacturing processes from die shots of NMOS NS32k chips seems to be possible.
I also have 32032 waiting opened for die shot that I'll try to take next week. Unfortunately, 32332 is still missing and I don't know how to find such chip, so I hope someone could help me get this important missing die shot. |
