NXP RW610FML Module Brings Wi-Fi 6 and BLE 5.4 Connectivity
The RW610FML combines a 260 MHz Cortex-M33 MCU, dual-band Wi-Fi 6, BLE 5.4, 8 MB Flash, and advanced security in a compact module.
RW610FML wireless module
NXP Semiconductors recently unveiled the RW610FML, an innovative portable, ultra-low-power, standardised Wi-Fi 6 and Bluetooth Low Energy (BLE) 5.4 wireless communications module based on the organisation’s RW610 Arm Cortex-M33 microcontroller capable of supporting IEEE 802.11a/b/g/n/ac/ax and Bluetooth Low Energy (LE) protocols and aimed at low-power Internet of Things (IoT) devices.
The surface-mount module is designed for smart appliances, home automation, industrial gateways, and medical devices and integrates the 260 MHz Arm Cortex-M33 wireless SoC with 1.2MB of on-chip static RAM (SRAM), a quad serial peripheral interface (QSPI) supporting execute-in-place (XIP) from external flash, 8MB of on-module NOR flash, a built-in antenna, an RF matching circuit, and a crystal oscillator.
Previously, we covered the Murata Type 2FR/2FP IoT module, which also integrates the NXP RW610 SoC. It features security technologies such as EdgeLock Assurance and supports the Matter protocol. Feel free to check out this module as well.
