Musical Mobile

This is the chip from a musical mobile that played Mozart, Bach, nature and island sounds.

It's pretty likely that the four blocks in th eimage are where the data for the four different sounds is located.

Tyre Pressure Gauge Main IC

This is the main chip from a tyre pressure gauge. It's an AMI, but I can't see any part number on there. It's made in Idaho though, if you look carefully.

I'm not sure if this is a microcontroller. I'm tending towards not, as there doesn't seem to be any ROM or RAM, at least not in quantity. It looks to me like this is discrete logic, in the top half, with some registers and so on dotted about.

Pressure Sensor

This is the sensor from a cheap air pressure gauge for car tyres.
It shows what is probably a bridge arrangement.

This was imaged through the clear coating that was on top of the die. The die was mounted directly on the PCB.

Debit Card

Not a lot to see here. This was not a 'contactless' card. The panorama creation decided to lose a bit, but most of the die is there.

Casio Quartz Watch

Lorus V33 Quartz Watch

Seiko 7810-5069 Quartz Watch

Casio fx-602p

This is the main chip inside a casio fx-602p calculator from the 1980s.

Unfortunately the ROM contents are not visible, I have to remove a layer to get at them. Other circuitry is visible though.

Pulsar Watch

This is the die from a Pulsar analogue quartz watch that I dismantled.

MT25Q128 Serial SPI Flash

MT25Q128 Serial SPI Flash

This is a modern device, it's difficult to see much detail in it. Some damage to corner, I had to heat and ultrasonic clean several times to get a clean surface. There's still contaminant left in one area.
