Ti CD4046BE - CMOS PLL / Oscillator : weekend die-shot
We used to think that 4000-series or 7400-series standard logic are all relatively simple ICs. Ti CD4046BE is probably the most complex of these - It's a PLL with internal VCO and even zener voltage reference for external voltage regulator. It could still be useful today, if you're fine with it's 1.4Mhz frequency limit.Die size 2271x2007 µm.

Ti SE555P - 1996 version in glass-filled DIP package: weekend die-shot
Some time ago we've seen Ti's 555 from 2006. This is an older one, from 1996. Die here is slightly larger, transistors are square vs round and no pads in the middle of the chip.Die size 1000x1020 µm.
