32-bit load/store AVR32A RISC architecture.
3 stage pipeline allows one instruction per clock cycle for most instructions.
MPU allows for operating systems with memory protection.
IEEE1149.1 compliant JTAG and boundary scan
Direct memory access and programming capabilities through JTAG interface
Extensive On-Chip Debug features in compliance with IEEE-ISTO 5001-2003 (Nexus 2.0) Class 2+
Auxiliary port for high-speed trace information
Hardware support for 6 Program and 2 data breakpoints
Unlimited number of software breakpoints supported
Advanced Program, Data, Ownership, and Watchpoint trace supported
Transfers from/to peripheral to/from any memory space without intervention of the processor.
Next Pointer Support, forbids strong real-time constraints on buffer management.
Fifteen channels
High Speed Bus (HSB) matrix with 6 Masters and 6 Slaves handled
