Silicon Labs has introduced basic availability of its FG23L wi-fi system-on-chip (SoC) household, its newest “Collection 2” sub-gigahertz elements — with developer kits now accessible and full basic availability scheduled for September thirtieth.
“The FG23L extends Silicon Labs’ confirmed sub-GHz management into the high-volume, cost-sensitive section of the market,” claims Silicon Labs senior vice-president for Web of Issues merchandise Ross Sabolcik of the launch. “By delivering the best-in-class mixture of vary, effectivity, and safety on the business’s best price-performance, we’re enabling prospects to deliver extra related gadgets to market quicker and at decrease value than ever earlier than.”

The FG23L elements are constructed round Arm’s 32-bit Cortex-M33 microcontroller core operating at as much as 78MHz and together with each floating-point unit and digital sign processing (DSP) extensions, with 32kB of static RAM (SRAM) and 128kB of flash reminiscence. Peripherals embody an analog-to-digital converter (ADC) that may run at one mega-samples per second (MSps) at 12-bit precision or 76.9kSps at 16-bit precision, two analog comparators, two digital to analog converters, a low-energy sensor interface, three EUSART and one UART bus with the latter doubling as SPI, SmartCard, IrDA, or I2S, two I2C buses, a keypad scanner, built-in temperature sensor, an eight-channel direct reminiscence entry (DMA) controller, and as much as 23 general-purpose enter/output (GPIO) pins with output state retention and asynchronous interrupts.
The chips additionally embody built-in sub-gigahertz radio modules delivering a claimed hyperlink price range ~146dB for as much as twice the vary of “comparable gadgets” but with a low sufficient energy consumption to ship a claimed 10 years of battery life in widespread utilization situations: 4.2mA obtain present for 400kbps 4-FSK alerts at 920MHz and as little as 25mA transmit at 14dBm on 915MHz rising to 85.5mA for the extra highly effective 20dBm fashions. The chip as an entire attracts a claimed 26µA/MHz when clocked to 39MHz, half its rated clock pace, and 1.5µA in deep sleep with full RAM retention dropping to 1.2µA with 16kB retained and the real-time clock operating from LFRCO.

Lastly, the chips embody the mid-range implementation of Safe Vault — providing a real random quantity generator (TRNG), a cryptographic acceleration engine, Safe Boot and Safe Software Boot capabilities, RTSL help, Safe Debug lock and unlock, and an built-in safety engine.
Pricing for the brand new chips begins at $2.05 in single-unit portions for the 14dB transmission energy variant; a developer equipment for a similar chip is accessible from Silicon Labs direct at $202. Full availability is scheduled for September thirtieth, with extra data accessible on the official product web page.
