Small off-the-shelf small ARM module (15mmx25mm or less)?

We are looking for off-the-shelf small ARM module (15mmx25mm or less) with the following specs:

- single core >= 100MHz is OK
>= 256k RAM
>= 256kb ROM
>= 2mbit flash
- battery charging circuit
- uart i/f
- optionally, a separate Bluetooth radio (with own CPU) with 2-3 wire i/f to ARM CPU

- availability of evaluation kit, development software and license-free rtos (Linux-like OS is not an option)

All pointers appreciated.
