Built around the NXP RW612 wireless MCU, Quectel’s FCM365X module combines dual-band Wi-Fi 6, Bluetooth LE 5.4, Zigbee, and Thread connectivity in a single device. It integrates a 260-MHz Arm Cortex-M33 processor with TrustZone, 1.2 MB of SRAM, and 8 MB of flash, with optional PSRAM expansion.
The FCM365X gives developers the flexibility to support multiple wireless protocols while simplifying device design. Zigbee and Thread enable low-power, reliable mesh networking across smart home and industrial IoT ecosystems, with Thread emerging as a key technology for Matter-enabled devices.
Suited for power-constrained applications, the FCM365X offers multiple low-power modes and keep-alive mechanisms. Standard interfaces include GPIO, SDIO, UART, USB, SPI, and JTAG, while the QuecOpen SDK enables access to I²C, I²S, ADC, LCD, and PWM. The module also complies with WPA-PSK, WPA2-PSK, and WPA3-SAE security standards and uses AES-128 encryption.
The FCM365X is housed in an LCC+LGA surface-mount package with a compact footprint of 25.5×18.0×3.16 mm. A timeline for availability was not provided at the time of this announcement.
