AM67A94AKGHIAMWR-Texas Instruments-Price, Stock & Datasheet

The AM67x scalable processor family is based on the evolutionary Jacinto™ 7 architecture, targeted at Smart Vision Camera and General Compute applications and built on extensive market knowledge accumulated over a decade of TI’s leadership in the Vision processor market. The AM67x family is built for a broad set of cost-sensitive high performance compute applications in Factory Automation, Building Automation, and other markets.

The AM67x provides high performance compute technology for both traditional and deep learning algorithms at industry leading power/performance ratios with a high level of system integration to enable scalability and lower costs for advanced vision camera applications. Key cores include the latest Arm and GPU processors for general compute, next generation DSP with scalar and vector cores, dedicated deep learning and traditional algorithm accelerators, an integrated next generation imaging subsystem (ISP), video codec, and MCU cores. All protected by industrial-grade security hardware accelerators.

AM67x contains up to four Arm® Cortex®-A53 cores with 64-bit architecture, a Vision Processing Accelerator (VPAC) with Image Signal Processor (ISP) and multiple vision assist accelerators, Deep Learning (DL), Dense Optical Flow (DOF) video and 3D Graphics accelerators, a Cortex®-R5F MCU Island core and two Cortex®-R5F cores for Device and Run-time Management. The Cortex-A53s provide the powerful computing elements necessary for Linux applications as well as the implementation of traditional vision computing based algorithms. Building on the existing world-class ISP, TI’s 7th generation ISP includes flexibility to process a broader sensor suite including RGB-InfraRed (RGB-IR), support for higher bit depth, and features targeting analytics applications. Key cores include two “C7x” next generation DSP with scalar and vector cores, dedicated “MMA” deep learning accelerator combined with a large 2.25MB L2 memory enabling performance up to 4 TOPS within the lowest power envelope in the industry when operating at the typical automotive worst case junction temperature of 125°C.

The AM67x integrates high-speed IOs including a PCIe Gen-3 (1L) and 3-port Gigabit Ethernet switch with one internal port and two external ports with TSN support. In addition, an extensive peripherals set is included in AM67x to enable system level connectivity such as USB, MMC/SD, four CSI2.0 Camera interface, OSPI, CAN-FD and GPMC for parallel host interface to an external ASIC/FPGA. AM67x supports secure boot for IP protection with the built-in HSM (Hardware Security Module) and employs advanced power management support for power-sensitive applications.
