AMICCOM’s next-generation SoC, the A9146M4, has successfully obtained WiSUN FAN 1.0 certification. This certification not only signifies our technical strength in the field of wireless communication but also demonstrates our commitment to providing customers with high-quality wireless products. Wi-SUN (Wireless Smart Utility Network) is a wireless communication standard designed specifically for Internet of Things (IoT) applications. The Wi-SUN Alliance is a global organization dedicated to standardizing and promoting Wi-SUN technology. Wi-SUN finds wide applications, including Smart Grid, Smart Cities, Industrial Automation, Agricultural Applications, and Smart Home.

The A9146M4 is an excellent wireless communication chip, and we firmly believe that it will bring endless possibilities to customers and contribute to their success in the market. Meanwhile, we are actively verifying and developing chips for WiSUN FAN 1.1 applications to further expand our product line and meet the growing demands of our customers. WiSUN FAN 1.1 will bring more new features and performance enhancements, making our products more diverse and powerful.

A9146M4 is a high performance and low cost SoC. It integrates M4F micro controller, 512Kbytes/1Mbtes flash memory, 80KBytes SRAM compatible controller and various powerful functions.

A9146M4’s RF is a monolithic low-IF architecture CMOS FSK/GFSK TRX for wireless applications in the 169/315/433/470/868/ 915MHz ISM bands. This device is especially suitable for battery-powered application and the 470MHz ~ 510MHz wireless AMR (Auto Meter Reading) in China and 169.4MHz/433.8MHz/868.3MHz wireless M-bus in Europe. For Wi-SUN and IEEE 802.15.4g applications, A9146M4 also built in HW 802.15.4g packet handling and HW-accelerated IEEE 802.15.4 compliant MAC features.

A9146M4’s RF control registers are accessed via 3-wire or 4-wire SPI interface including TX/RF FIFO, VCO frequency, and chip calibration procedures. Another one, via SPI as well, is the unique Strobe Command, A9146M4’s RF can be controlled from power saving mode (deep sleep, sleep, idle, standby), PLL mode, TX mode and RX mode.

In FIFO mode, preamble is self-generated by A9146M4’s RF. User just needs to assign the sync word to this device by ID R/W command via SPI. For payload, the built-in separated 2048-bytes TX/RX FIFO are used for this purpose to let user R/W the wanted payload. User can also enable additional packet features like CRC for error detection, FEC (hamming 7 by 4) for 1-bit data correction per code word, Manchester coding, as well as data whitening for data encryption / decryption.

Additional device features such as on-chip regulator, RSSI for clear channel assessment, a thermal sensor, low battery detector, carrier detect, preamble detect, frame sync in FIFO mode, auto-ack and auto-resend, AIF (Auto IF function), AFC (Auto Frequency compensation), Auto calibration (VCO, IF Filter), PLL/CLK Generator, on-chip compensated capacitors of Xtal loading, and WOR (Wake on RX) to support the ability to periodically wake up from sleep mode to RX mode and listen for incoming packets without MCU interaction, which can be used to simplify system development and cost.

Overall, A9146M4’s highly integrated features and low current consumption offer a reduced BOM cost for high performance ISM bands product. All features are integrated in a small QFN 6X6 48 pins package.

We will continue to strive tirelessly to provide our customers with the highest quality products and services. If you have any questions or requirements regarding the A9146M4 or any of our other products, please feel free to contact us.
