2.2.9 Comparison Between TIDA-010967 and IWRL6432AOPEVM

The TIDA-010967 and IWRL6432AOPEVM are both designs to evaluate the IWRL6432AOP mmWave radar sensor, but these designs serve different purposes and are optimized accordingly. This section contains a detailed comparison highlighting the differences in design approach, hardware implementation, and use-case orientation.

The TIDA-010967 design has the following benefits:

  1. Easy to Production: The TIDA-010967 can be implemented directly on production hardware, making the design preferable for cost-sensitive end-product designs. Whereas, the IWRL6432AOPEVM is designed purely for evaluation and development purposes.
  2. Cost Optimization: The TIDA-010967 features a low-cost, two-power rail BOM-optimized design, reducing the BOM count and cost. The IWRL6432AOPEVM; however, is power-optimized and uses a broader set of components to support broader evaluation capabilities.
  3. Low-Cost PCB Stackup: The TIDA-010967 is built on a 2-layer PCB, offering a significant cost advantage for mass production. Whereas the EVM uses a 4-layer PCB to support better signal integrity and power distribution, preferable for development use.
  4. Easy to Test: The TIDA-010967 uses the FT230XS USB-to-UART converter, which is cost-effective and an excellent choice for small designs. The TIDA-010967 includes castellated pins to interface with customized production, hardware, and test. IWRL6432AOPEVM integrates the XDS110 debugger, offering UART and JTAG for comprehensive debugging.
  5. Small Board Size and Easy to Integrate: The form factor of the TIDA-010967 is small and compact, supporting easy integration with the main board of a customer, like a wireless module. The EVM is relatively large, which accommodates evaluation circuitry and debugging features.
