The 56F8157, a member of the 56800E core-based family of Digital Signal Controllers, combines the processing power of a DSP and the functionality of a microcontoller.  The 56F8157 offers identical memory and peripheral capabilities to the 56F8156, with 14 additional GPIO pins. The 160-pin LQFP package allows you to take advantage of the included external memory interface and additional on-chip memory to satisfy the growing functional needs of your design.
