66AK2L06XCMS2

Overview

The Texas Instruments 66AK2L06XCMS2 is a KeyStone II System-on-Chip (SoC) featuring four TMS320C66x DSP cores and two ARM Cortex-A15 processors. Operating at up to 1.2 GHz, the C66x cores deliver 38.4 GMACs/core for fixed-point and 19.2 GFLOPs/core for floating-point processing. The device integrates a Digital Front End (DFE), Fast Fourier Transform Coprocessors (FFTC), and JESD204B interfaces for direct ADC/DAC connectivity. It includes a Network Coprocessor with four Gigabit Ethernet ports, a Security Accelerator, and 2 MB of MSMC SRAM. The component is housed in a 900-pin FCBGA package.

Feature Summary

• Integrated DFE and IQNet supporting up to four JESD204A/B lanes
• Two FFT Coprocessors supporting up to 1200 Msps at size 1024

Applications

• Medical imaging systems
• Avionics and defense platforms
• Test and measurement equipment
• Industrial control applications

Procurement Notes

Verify the 'X' prefix indicates an experimental or pre-production status rather than a fully qualified production device. Confirm the 'CMS' suffix corresponds to the 900-pin plastic ball grid array package. Ensure the temperature range matches the specific application requirements, as the base model supports commercial temperatures while extended ranges require specific suffixes.

Selection Notes

Select this SoC for applications requiring high-performance signal processing with low power consumption. The integrated JESD204B interface simplifies connections to high-speed data converters. Evaluate the need for the Security Accelerator, which may be subject to export controls and enabled only for approved shipments. Consider the available development tools, such as Code Composer Studio and MCSDK, for software implementation.

Part Context

The 66AK2L06XCMS2 belongs to the 66AK2Lxx family within the KeyStone II architecture. It serves as a low-power solution designed to meet stringent power, size, and cost requirements for ADC and DAC-based applications. The device leverages the Multicore Navigator and TeraNet switch fabric for efficient packet-based communication between cores and peripherals.
