Looking for MCU with AES. Migrating from STM32F107

Question

I'm looking for Microcontrollers based on the ARM Cortex-M3. The MCU should have an AES Accelerator, SPI, (at least 3) USARTs, USB OTG. I'm migrating from STM32F107 (the reason I'm migrating is because I need the AES by hardware) any good recommendations that will save me time in the migration process? I've been looking in the ST and ATMEL website, but I haven't found one that have the characteristics I need.

Thanks in advance.
