Silicon Labs has introduced two new system-on-chip (SoC) households, the SiXG301 and SiXG302 — its first wi-fi SoCs to be constructed on a 22nm course of node, delivering improved efficiency and effectivity.
“Sensible gadgets have gotten extra advanced, and designers are challenged to pack larger performance into smaller areas whereas sustaining vitality effectivity,” says Silicon Labs’ Ross Sabolcik of the necessity for the corporate’s new Sequence 3 components. “With the SiXG301 and upcoming SiXG302 households, we’re delivering versatile, extremely built-in options that allow next-generation IoT [Internet of Things] gadgets — whether or not they’re plugged in or operating on battery energy.”

The SiXG301 is designed for the previous class of gadgets, that includes a single Arm Cortex-M33F core operating at as much as 150MHz, as much as 512kB of static RAM (SRAM), as much as 4MB of co-packaged flash storage plus a quad-SPI interface for exterior flash, and the customer’s alternative of a multi-protocol radio supporting Bluetooth Low Power (BLE), IEEE 802.15.4 together with Zigbee, OpenThread, and Matter, proprietary 2.4GHz, and each DMP and CMP within the SiMG301 or BLE and proprietary 2.4GHz solely within the SiBG301.
Each gadgets supply peripherals together with an elective PIXELRZ single-wire interface for LED controllers, an LED pre-driver, a 12-bit analog-to-digital converter, two analog comparators, as much as 28 general-purpose enter/output (GPIO) pins, three EUSART buses supporting UART, SPI, DALI, IrDA, and SmartCard operation, three I2C buses, and an on-die temperature sensor. Energy draw for each is rated at 8.1mA obtain and 11.4mA 0dBm transmit rising to twenty-eight.6mA at 10dBm output energy and 47μA/MHz in energetic mode at 150MHz.

The SiXG302, in the meantime, is the household designed for battery-powered gadgets. This, the corporate says, will supply an energetic energy draw of simply 15µA/MHz — not solely significantly beneath the SiXG301 vary however a claimed 30 p.c beneath chip choices from the corporate’s rivals. A lot of that is attributed to a shift to a 22nm semiconductor course of node, a primary for the corporate’s wi-fi system-on-chip portfolio.
