34xx max supported ddr frequently is 166mhz.
there should be no issue running a 200mhz rated ddr at 166.
the real issues are with pin level interfacing.

Subject: LPDDR memory for TI OMAP 3503 processor
Hi,
Is the micron 2GB POP LPDDR memory compatible with the TI
OMAP3503 processor? http://www.micron.com/products/partdetail?part=MT46H64M32L2JG-5%20IT
Quote from the technical reference manual:
"The SDRC module only supports low-power double-data-rate (LPDDR)
SDRAM devices. Memory devices can be interfaced to the SDRC using a
stacked-memory approach or through the printed circuit board (PCB).
The stacked-memory approach uses the package on package interface pins
(available on CBB & CBC package). The LPDDR interface on the top of
the POP package has been designed for compatibility any POP LPDDR
device with a matching footprint and compliance with the JEDEC
LPDDR-266 specification."
My point of confusion is
a. the Micron 2GB memory is stated to have a 200MHz clock rate and the
data rate is LPDDR400.
b. in the term JDEC LPDDR-266, does the 266 correspond to the data
rate? If so, can I use the LPDDR400 memory with the OMAP3503
processor, which requires an LPDDR-266 memory?
Best regards,
Elvis Dowson
