Subject: LCD Clock ICs - Do Any Vendors Sell Them?

Can anyone tell me if any of the usual IC
vendors sell the types of CMOS Clock ICs
used in low cost LCD alarm clocks.
Timekeeping ICs like the LM8562 and older
LM8360 series are available for LED use
but for LCD displays and low power
applications all clock ICs seem to exist
only in dice form attached to the circuit
board under black epoxy. I need the
equivalent ICs in packaged form. The
alternatives and drawbacks are 1) a RTC
plus microcontroller (consumes too much
power), 2) use discrete CMOS ICs ( package
count too high), 3) adapt LED clock chip
to drive LCD (kludgy, high package count),
4) reverse engineer existing LCD clocks.
Of these options, No 4 seems to be best
if LCD clock ICs are not available. Can
someone help to point me towards a source
of these ICs?
