Telink Semiconductor has launched the ML9118A, a compact wireless module that combines Wi-Fi 6, Bluetooth 5.4, and 802.15.4 connectivity for smart home applications. The 25.5 x 18 mm (1.0 x 0.7 inches) module packs a dual-core RISC-V processor running at 160 MHz, 576KB SRAM, and 4MB flash storage alongside support for Matter 1.3, Zigbee 3.0, and Thread protocols.
The module's tri-radio design positions it as a competitor to solutions like the Espressif ESP32-C6 and NXP iW612. The ML9118A delivers 15dBm transmit power in Bluetooth LE mode and achieves receiver sensitivity down to -98dBm for Zigbee. Peripheral interfaces include SDIO 2.0, up to 19 GPIOs, dual SPI and I2C buses, three UARTs, and I2S for audio applications. Security features span AES-128/256 encryption, SHA hash algorithms up to SHA-512, RSA2048 and ECC256 signature authentication, secure boot, and OTA updates.
Telink offers the AIOT-DK2 development kit featuring the ML9118A module, a 3.5mm audio jack, speaker and microphone headers, USB Type-C power input, GPIO expansion connectors, and JTAG debugging interfaces. The company provides a Zephyr SDK that works across its wireless chip lineup, along with a user manual for the development board.
The ML9118A module and AIOT-DK2 board are available now through Telink's sales channels, though pricing has not been disclosed. Additional documentation including the TLSR9118 datasheet and hardware design files can be obtained through Telink representatives.
