AWR2944P/AWR2E44P 是 AWR2944 产品系列的“性能”扩展，具有增强的射频和计算性能，可满足 NCAP 和自动驾驶要求。AWR2944-ECO/AWR2E44-ECO 和 AWR2944LC/AWR2E44LC 是主流型号，并分别采用该系列中经过优化的型号，使客户能够在该系列的 P、ECO 和 LC 器件之间提供可扩展的产品系列。AWR2944P/AWR2E44P/AWR2944-ECO/AWR2E44-ECO/AWR2944LC/AWR2E44LC 也是一款单芯片毫米波传感器，由能够在 76GHz 至 81GHz 频段内工作的 FMCW 收发器、雷达数据处理元件和车载网络外围设备构成。雷达传感器采用 TI 的低功耗 45nm RFCMOS 工艺制造，所采用的设计可增强射频和计算性能，从而在小型封装中以超低 BOM 数量实现出色的集成度。AWR2944P/AWR2E44P/AWR2944-ECO/AWR2E44-ECO/AWR2944LC/AWR2E44LC 设计用于汽车领域中的低功耗、自监控、超精确雷达系统。
AWR2E44P/AWR2E44-ECO/AWR2E44LC 型号为客户提供了非凡的封装上装载 (LOP) 天线特性，便于将天线直接连接到封装上。LOP 技术可以通过 PCB 中的孔将信号从 AWR2E44P/AWR2E44-ECO/AWR2E44LC 芯片无损传输到天线，并在芯片底部装载。芯片和天线直接焊接到 PCB 上，因此可采用低成本 PCB 材料而非昂贵的高频材料。
TI 的低功耗 45nm RFCMOS 工艺可实现具有集成 PLL、VCO、混频器和基带 ADC 的单片实施 4 TX、4 RX 系统。DSP 子系统 (DSS) 中集成了 TI 的高性能 C66x DSP，可用于处理雷达信号。该器件包含一个无线电处理器子系统 (RSS)，该子系统负责雷达前端配置、控制和校准。在主要子系统 (MSS) 中，该器件实现了一个用户可编程的 Arm Cortex-R5F 处理器，允许自定义控制和汽车接口应用。硬件加速器块 (HWA 2.1) 通过卸载通用雷达处理（例如 FFT、恒定误报率 (CFAR)、扩展和压缩）来对 DSS 和 MSS 进行补充。这会节省 DSS 和 MSS 上的 MIPS，为自定义应用和更高级别的算法腾出了资源。
器件中还提供了硬件安全模块 (HSM)（仅适用于安全器件型号）。HSM 由可编程 Arm Cortex-M4 内核和必要的基础设施组成，用于在器件内提供安全的操作区域。
AWR2944P/AWR2E44P/AWR2944-ECO/AWR2E44-ECO/AWR2944LC/AWR2E44LC 还包含一个用于配置和控制硬件加速器模块 (HWA 2.1) 的 Cortex-M4 处理器。
简单编程模型更改可支持各种传感器实施（近距离、中距离和远距离），并且能够进行动态重新配置，从而实现多模式传感器。
此外，AWR2944P/AWR2E44P/AWR2944-ECO/AWR2E44-ECO/AWR2944LC/AWR2E44LC 作为完整的平台器件提供，其中包括 TI 硬件和软件参考设计、软件驱动程序、示例配置、API 指南以及用户文档。
