Sector 3: cells
Standard cells

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: ?
