#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.

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.
