#icreverseengineering — Public Fediverse posts

I don't think I'll tell Travis Goodspeed what I'm doing to his wonderful tool...

(I'm adding template matching to MaskRomTool and it's doing a *spectacular* job at detecting flipped bits based on their diffusion shape)

Lunchtime project complete - this is the MKS GEN 1.4 (RAMPS 1.4) board which runs my CNC microscope. It now has RGB LED and halogen lamp brightness controls. #pyuscope #icre #icreverseEngineering

Which pad is which? #BSBACM edition.
First we trace out the power pads...

There are 52 bond pads and 48 pins, so 4 of those pads need to double up...

I would love to know why the Acorn/#ARM Albion IOC has an all-seeing-eye symbol on the die. #ICReverseEngineering #ICRE

Any #ICRE #ICReverseEngineering folks recognise these logos or the text? They're on a bunch of random silicon dice and packaged chips I was given.

They turned up at an estate sale in Bristol earlier this year.

Boosts appreciated

Chips a la Phil #icre #ICReverseEngineering

Hello and welcome to this installment of #nakeddiefriday, hope you all are doing well. Today I got a visually interesting specimen for you, this one is a NEC uPD76F0102 which is some kind of a microcontroller unit with no public datasheet. It came from a body control unit made by Denso, so duh.

Let's run a short thread on this one.

For no particular reason.

I do not know the history behind this doodle.

I've been taking the tops off silicon chips again ...!

This time it's a weird chip called the M4613D/A which turned up in a Blaupunkt data terminal. A computer museum in Spain dumped the ROMs, and Pernod is working on a MAME emulation...

Hello and welcome to this week's installment of #nakeddiefriday !

The guest of today is the TIBPAL16R4 by TI, a programmable array logic chip made with bipolar logic. The die has 2 metal layers, its maskwork produced in 1985. A short thread follows.

NXP tl T6C10V0C. Anyone know what that is? Mask date of 2012. #ICRE #ICReverseEngineering

Slightly disappointed. Decapped the Rucify ASIC from a Zip drive last night. Can't see anything through the brown polyimide topcoat. Flame torching the topcoat didn't do anything, but a hot rosin boil removed the die attach compound.
This is going to need some headscratching. #ICReverseEngineering #ICRE

Another great #38c3 talk, "Proprietary ICs and dubious marketing claims - let's fight these with a microscope!" by Giulio Zausa.

Reverse engineering the gate arrays from a Roland piano using Inkscape and Verilog - neat!

Great talk by Aedan Cullen (@aedancullen) at #38c3 on breaking security on the #RP2350 by glitching the OTP VDD.

I expect the bus between the state machine and OTP is like Wishbone or M68K and has a request and an acknowledge, and the data is latched on the ACK. No ACK? Guard word stays in the latch.

If you remember the ARM250 I decapped earlier ... I've uploaded a zoomable 100x photo to Silicon Pr0n: https://siliconpr0n.org/map/gec-plessey/arm250/philpem_mz_ms10x/

Well this was certainly "fun". I've hacked up Pyuscope to talk to the Raspberry Pi Camera (via Gstreamer). Catch is the resolution is limited to 1920x1080. Seems to be some kind of quirk in the #RaspberryPi image processor or libcamerasrc? #ICRE #ICReverseEngineering
