66AK2G12ABYA100E

Overview

The Texas Instruments 66AK2G12ABYA100E is a multicore System-on-Chip (SoC) based on the Keystone II architecture, integrating one Arm Cortex-A15 core and one C66x DSP core. Both processors operate at a maximum frequency of 1 GHz. The device features 32 KB L1 instruction and data memory per core, with 512 KB L2 memory for the Arm subsystem and 1 MB configurable L2 memory for the DSP. It includes an industrial subsystem with two PRU-ICSS units, a single-lane PCIe 2.0 port, dual USB 2.0 ports, and extensive connectivity options including Ethernet MAC, QSPI, MMC/SD, and multiple serial interfaces. The component is housed in a 625-ball FCBGA package.

Feature Summary

• Heterogeneous multicore architecture combining an Arm Cortex-A15 microprocessor and a C66x VLIW DSP, both running up to 1 GHz.
• Integrated industrial subsystem featuring two Programmable Real-Time Unit and Industrial Communication Subsystems (PRU-ICSS).
• Comprehensive memory hierarchy including MSMC shared SRAM, DDR3L external memory interface supporting up to 4 GB, and GPMC.
• Robust security and reliability features such as ECC protection across processor cores, shared memory, and external memory interfaces.

Applications

• Industrial Communications and Controls
• Home Audio Systems
• Professional Audio Processing
• Protection Relays
• Industrial Transport

Procurement Notes

Verify the specific speed grade suffix '100' against the official datasheet Table 5-1 to confirm operating temperature range and performance characteristics. Ensure compatibility with the required DDR3L memory configuration and power supply voltages during board design. Confirm that the FCBGA-625 package footprint matches the target PCB layout guidelines provided in the documentation.

Selection Notes

Select this SoC for applications requiring simultaneous real-time DSP processing and high-level OS execution on an Arm core. The inclusion of PRU-ICSS makes it suitable for deterministic industrial control tasks. Evaluate the available GPIO count (up to 212) and peripheral interfaces against system requirements. Consider the thermal dissipation capabilities of the 21.0 mm x 21.0 mm package for the intended operating environment.

Part Context

This component belongs to the 66AK2G1x family of heterogeneous multicore SoCs from Texas Instruments. These devices are designed using the field-proven Keystone II architecture to deliver high performance with low power consumption. The family targets embedded applications needing robust connectivity and hardware acceleration for network and cryptographic functions.

Replacement Considerations

Consult the Device Comparison section in the datasheet for related products within the 66AK2x Multicore DSP + Arm Processors line. Verify pinout and feature compatibility before substituting with other members of the 66AK2G1x series or companion products recommended by Texas Instruments.
