I would like to identify a micro used in a device I need to interface 
to. It seems to be 68 pins, chip on board, (so no part numbers)
and has an LCD driver on board, as well as SPI and 32Khz osc.

Is there a site that has pin summaries for various uC/s that would
help narrow the selection? I've been going at this for a long time now.
I thought it might be a popular processor (like PIC or AVR or Freescale,
but nothing I have found comes close to the pin sequence I have.

 From the layout and silkscreen it has, near pin 1

SDAT
SCLK
xtal
xtal
Vpp
32kHz
32kHz
Reset

I am certain of the Reset, xtals & Vpp pinning.
SDAT/SCLK could be bit banged I suppose.

The pins for the rest of the device drive a 32 segment x 4 com
mutiplexed LCD directly, without ANY bias resistors (pins 68 to 34 ish)
so I'm looking for micros with LCD drivers on board.
Seems to be quadruplex mode (4 levels for the segments. 0, 1, 2 & 3 V)
Pins from 17 to 34 seem to be I/O since they drive two 6 bit buffers
and a serial memory device.

If anyone recognizes the pin sequence I'd appreciate a pointer
to a possible CPU.

Thanks in advance for you curiosity and help.

Robert
