AMW006/T WiFi 802.11b/g/n Transceiver Module Equivalent & Substitute Parts

Part Overview

The AMW006/T is a WiFi 802.11b/g/n transceiver module manufactured by Silicon Labs, designed for 2.4GHz integrated trace antenna surface mount applications. This module integrates the BCM43362 IC and provides serial communication via SPI and UART interfaces. The product is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMW006/T is determined by the following critical parameters:

• RF Standard & Frequency: Both parts must support WiFi 802.11b/g/n at 2.4GHz
• Antenna Configuration: Integrated trace antenna required for form factor compatibility
• Mounting Type: Surface mount (SMD) module format
• Voltage Supply: 3.3V nominal operation
• Serial Interfaces: SPI and UART support for host communication
• Package Type: SMD module with compatible pinout and footprint

The ATWILC1000-MR110PB from Microchip Technology meets these core substitution criteria. While it offers enhanced specifications in certain parameters (higher data rate, improved sensitivity, extended voltage range), it maintains compatibility with the fundamental electrical and mechanical requirements of the AMW006/T application space.

Engineering Selection Recommendations

Product Status Consideration: The AMW006/T is discontinued at DiGi Electronics, while the ATWILC1000-MR110PB remains in active production with 2200 units in stock. For new designs or production continuity, the ATWILC1000-MR110PB provides an active alternative.

Compliance & Certifications: Both parts share identical ECCN classification (5A992C) and MSL rating (3, 168 Hours). The ATWILC1000-MR110PB carries RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

Electrical Performance: The ATWILC1000-MR110PB meets or exceeds all electrical specifications of the AMW006/T, including data rate, power output, and sensitivity. The extended voltage supply range (3.3V ~ 4.3V) and lower operating temperature limit (-40°C) provide additional design flexibility.

Package Consideration: The substitute uses a 28-SMD Module format with exposed pad versus the original 52-SMD Module. PCB layout and footprint verification is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the ATWILC1000-MR110PB directly replace the AMW006/T without PCB modifications?

A: The electrical specifications are compatible, but the package format differs (28-SMD Module vs. 52-SMD Module). PCB footprint and layout modifications are necessary.

Q: Are the serial communication interfaces compatible?

A: The ATWILC1000-MR110PB supports SPI and UART, matching the AMW006/T requirements. The substitute additionally provides I2C and SDIO interfaces, which are optional for compatibility.

Q: What is the impact of the different current consumption specifications?

A: The ATWILC1000-MR110PB specifies current ranges (29mA ~ 68mA receiving; 29mA ~ 230mA transmitting) versus fixed values for the AMW006/T (5.7mA receiving; 11.4mA transmitting). Power supply design must accommodate the higher maximum current draw of the substitute.

Q: Are both parts suitable for the same operating temperature range?

A: The ATWILC1000-MR110PB extends the lower temperature limit to -40°C compared to the AMW006/T at -30°C. Both support 85°C maximum. The substitute is suitable for wider temperature applications.

Q: What certifications apply to the substitute part?

A: The ATWILC1000-MR110PB is RoHS3 compliant and REACH unaffected, with identical ECCN and HTSUS classifications to the original part.
