4 88W8987-based wireless modules
4.1 88W8987 with i.MX 8M Quad
The 88W8987 is a highly integrated Wi-Fi (2.4/5 GHz) single-chip solution, specifically
designed to support the speed, reliability, and quality requirements of Very High
Throughput (VHT) products. The System-on-Chip (SoC) provides both simultaneous and
independent operation of IEEE 802.11ac (Wave 2), 1x1 with data rates up to MCS9 (433
Mbit/s). The 88W8987 provides the Wi-Fi feature to connect with the AP or STA. The
device requires a powerful host processor that supports both the low-level Wi-Fi driver
and the high-level Wi-Fi application software. The host interfaces include SDIO 3.0 for
connecting Wi-Fi technology to the host processor.

4.1.1 AzureWave AW-CM358MA module
The AW-CM358MA module supports a SDIO device interface that conforms to the
industry SDIO Full-Speed card specification and allows a host controller using the SDIO
bus protocol to access the Wireless SoC device.
The AW-CM358MA is a Wi-Fi 5 and Bluetooth 5 combo stamp module with M.2 adaptor
board that features:
• SDIO 3.0 standard
• On-chip memory used for CIS
• 4-bit SDIO and 1-bit SDIO transfer modes
• Special interrupt register for information exchange
