Sector 1: (CPU) cells

Main standard cell area. Probably what one would call the “CPU”

Sector 2: cells

Standard cells in two columns. The left column is solid and the right is maybe 4 discrete areas

Sector 3: cells

Standard cells

Sector 4: cells

Standard cells

Memory

RAM

SRAM

There are essentially 4 different types that are mirror images of each other. This is the upper left hand cell and the others can be derived from it pretty easily.

Composite polygons:

Raw layers:

Project: final.tar.bz2

ROM

Mask ROM. Optically visible. delayered1 shot makes this easily readable.

Sector 5: osc?

Looks like analog circuitry. Could be the clock.

Sector 6: markings

The only text on the die. Reads:

SMSC 1C 1C
1C573718A
-1P95

Sector 7: ?

Sector 8: LCD decoder?

Sector 9: LCD driver?

Sector 10: ?

Pads

Scattered like roaches. The padframe is on all four sides. The left side is non-linear as it has two distinct blocks.
