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...

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

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.
