1. Features

1.1. Module content

• All-in-one Wi‑Fi^®/Bluetooth^® Low Energy/802.15.4 wireless microcontroller
• Embedded 40 MHz high-precision crystal
• All RF components for the transmission and reception matching network, including antenna filter
• Three versions:
  • Embedded antenna (-B version)
  • RF connector (-U version)
  • RF pin output (-P version)

1.2. Supported wireless connectivity standards

• IEEE 802.11b/g/n/ax™
• Bluetooth^® Low Energy 5.4

1.3. Regulation certifications

ST67W611M1 is certified for numerous countries and regions worldwide.

Thanks to these certifications, it is straightforward to certify the end product.

1.4. Wi-Fi^®

• Wi-Fi 6, 2.4 GHz RF transceiver
• Wi-Fi 20/40 MHz bandwidth, 1T1R
• Wi-Fi security: WPS, WEP, WPA, WPA2, WPA3
• STA, SoftAP, concurrent STA + SoftAP
• Maximum Tx power (11b 1 Mbps): 21 dBm
• Tx power (HE40 and MCS9): 16 dBm
• Rx sensitivity (HE40 and MCS9): -67 dBm
• Application throughput up to 17 Mbps (TCP)
• Target wake time (TWT): see Wi-Fi6 Target Wake Time (TWT)
• LDPC, STBC, beamforming, DL/UL OFDMA, MU-MIMO, spatial reuse (SR), dual carrier modulation (DCM), extended range (ER)⁽¹⁾
• A-MPDU, A-MSDU, immediate block ACK, fragmentation and defragmentation

⁽¹⁾.: Some of these features are linked to the support of multiple antennas. Supporting these features means supporting access pointing (AP) using them. It also means that ST67W611M1 can provide feedbacks to the AP on channel condition, which the AP can use to optimize the link. For beamforming, 'SU Beamformee' is supported.

1.5. Bluetooth^® Low Energy

• Maximum Tx power: +20 dBm
• Rx sensitivity:
  • Bluetooth^® Low Energy (2 Mbps): -96.5 dBm
  • Bluetooth^® Low Energy (1 Mbps): -99 dBm

1.6. System peripherals

• SPI: see ST67W611M1 SPI interface
• UART: see ST67W611M1 UART interface

1.7. Security

• PSA Level 1 certified
• Security system encryption engine
• Secure services: secure boot and over-the-air (OTA)
