I happend seen your inquiry,
There ATMEL release the SAM9X family to supplement their ARM926EJ serials MCUs ,
Take SAM9X25 for example, its i-data and r-data cache is 16KB, compare to SAM9G45 features 32KB i-data and r-data cache.
ATMEL said the chip will price at 6USD, however, we can get it at about 8USD in China now.
The EMBEST have a SAMICC brand to promotion ATMEL serials products
Like ATMEL SAM9G45 evaluation board and MBC-SAM9X25 Core board etc,
