Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC-WMX-KD69-VK-B is determined by the following critical parameters:

RF Protocol Compatibility: The main part supports 802.11a/b/g/n across dual bands (2.4GHz and 5GHz). Substitute parts must maintain backward compatibility with 802.11b/g/n at minimum for 2.4GHz operation.

Frequency Band Coverage: The original module operates on both 2.4GHz and 5GHz. Substitutes operating on 2.4GHz alone are acceptable for applications not requiring 5GHz functionality.

Serial Interface Support: The main part provides Ethernet, I2C, I2S, JTAG, SPI, SDIO, UART, and USB interfaces. Substitute parts must support core interfaces (SPI, UART, I2C) required for typical WiFi module integration.

Power Characteristics: Operating voltage (3.75V nominal), transmit/receive current consumption (700mA), and output power (17dBm) define the power budget requirements for substitution.

Antenna Configuration: The original uses U.FL chassis mount with no integrated antenna. Substitutes with integrated or trace antennas are acceptable alternatives for space-constrained applications.

Mounting and Form Factor: Chassis mount versus surface mount represents a mechanical substitution consideration based on PCB integration requirements.

Operating Temperature Range: Both parts maintain -40°C to 85°C operation, ensuring thermal compatibility.

Engineering Selection Recommendations

The ATWINC1500-MR210PB from Microchip Technology is an active substitute for the obsolete CC-WMX-KD69-VK-B. Selection of this substitute is based on the following engineering criteria:

Product Status: The CC-WMX-KD69-VK-B is obsolete, while the ATWINC1500-MR210PB maintains active product status with current manufacturing and support availability.

Regulatory Compliance: Both parts share identical ECCN classification (5A992C) and REACH unaffected status. The ATWINC1500-MR210PB additionally carries ROHS3 compliance certification.

Protocol Support: The substitute supports 802.11b/g/n, providing backward compatibility for 2.4GHz WiFi applications. Applications requiring 5GHz (802.11a) operation cannot use this substitute without additional 5GHz capable modules.

Power Efficiency: The ATWINC1500-MR210PB demonstrates significantly lower current consumption in receive mode (61mA versus 700mA) and reduced transmit current (265mA versus 700mA), resulting in improved power efficiency for battery-powered applications.

Interface Compatibility: The substitute provides SPI, UART, and I2C interfaces, covering the core serial communication requirements. Applications dependent on Ethernet, I2S, JTAG, SDIO, or USB interfaces require architectural redesign.

Antenna Integration: The integrated trace antenna eliminates external antenna requirements, reducing PCB footprint and component count compared to the U.FL chassis mount configuration.

Mounting Transition: Surface mount packaging requires PCB layout modification from the original chassis mount design.

Frequently Asked Questions (FAQ)

Q: Can the ATWINC1500-MR210PB replace the CC-WMX-KD69-VK-B in all applications?

A: No. The substitute is suitable only for 2.4GHz WiFi applications. Applications requiring 5GHz operation (802.11a) must use alternative 5GHz-capable modules. Additionally, applications dependent on Ethernet, I2S, JTAG, SDIO, or USB interfaces require redesign to use the available SPI, UART, and I2C interfaces.

Q: What are the power consumption differences between these modules?

A: The ATWINC1500-MR210PB consumes significantly less current: 61mA in receive mode compared to 700mA for the CC-WMX-KD69-VK-B, and 265mA in transmit mode compared to 700mA. This represents approximately 91% reduction in receive current and 62% reduction in transmit current.

Q: How do the antenna configurations differ?

A: The CC-WMX-KD69-VK-B uses an external U.FL connector for antenna attachment with no integrated antenna. The ATWINC1500-MR210PB features an integrated trace antenna, eliminating the need for external antenna components and reducing overall module size.

Q: What mounting changes are required?

A: The original module uses chassis mount configuration. The substitute employs surface mount technology, requiring PCB layout redesign and reflow soldering processes instead of connector-based mounting.

Q: Are there memory differences between these modules?

A: Yes. The CC-WMX-KD69-VK-B provides 512MB Flash and 512MB RAM, while the ATWINC1500-MR210PB offers 4MB Flash and 128kB RAM. Applications requiring large local storage or processing capability must account for this reduction.

Q: What is the voltage supply compatibility?

A: The CC-WMX-KD69-VK-B operates at 3.75V nominal. The ATWINC1500-MR210PB accepts 2.7V to 3.6V, providing broader supply voltage tolerance. Existing 3.75V supplies are compatible with the substitute within its specified range.

Q: Do both modules share the same regulatory classification?

A: Yes. Both modules carry identical ECCN classification (5A992C) and REACH unaffected status, ensuring equivalent export and environmental compliance requirements.
