Originally this was what we called the "black SecurID" but these have 2C dies in them as well.

====== Cells ======

[[1c_cells|Cell library]]

===== 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.

====== 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.
