66AK2G02 (ACTIVE)

Multicore DSP+ARM KeyStone II System-on-Chip (SoC)

 

Description

66AK2G0x is a family of heterogeneous multicore System-on-Chip (SoC) devices based on TI’s field-proven Keystone II (KS2) architecture. These devices address applications that require both DSP and ARM performance, with integration of high-speed peripheral and memory interfaces, hardware acceleration for network and cryptography functions, and high-level operating systems (HLOS) support.

Similar to existing KS2-based SoC devices, the 66AK2G0x enables both the DSP and ARM cores to master all memory and peripherals in the system. This architecture facilitates maximum software flexibility where either DSP- or ARM-centric system designs can be achieved.

The 66AK2G0x significantly improves device reliability by extensively implementing error correction code (ECC) in processor cores, shared memory, embedded memory in modules, and external memory interfaces. Full analysis of soft error rate (SER) and power-on-hours (POH) shows that the designated 66AK2G0x parts satisfy a wide range of industrial and automotive requirements.

Accompanied by the new Processor SDK, the 66AK2G0x development platform enables unprecedented ease-of-use with main line open source Linux, CCS 6.x, a wide range of OS-independent device drivers, as well as TI-RTOS that enables seamless task management across processor cores. The device also features advanced debug and trace technology with the latest innovations from TI and ARM, such as system trace and seamless integration of the ARM CoreSight components.

Secure boot can also be made available for anticloning and illegal software update protection. For more information about secure boot, contact your TI sales representative.
