COM-29062-RP2350-Microcontroller-Feature

The RP2350A IC represents Raspberry Pi’s next-generation microcontroller, offering a blend of high performance, robust security, and remarkable flexibility—all at an impressively low cost. Building on the success of the RP2040, the RP2350 features dual-core processing with a unique twist: you can choose between two Arm Cortex-M33 cores or two open-source Hazard3 RISC-V cores, selectable via software or OTP configuration. Running at 150 MHz with 520 KB of SRAM, this chip is ideal for demanding applications such as real-time control, edge AI, and secure IoT systems.

The standalone RP2350A is now available at SparkFun!

Starting with nothing but the sun, moon, and stars, humans have been keeping track of time for centuries, including when they invented the concept of a century. This week, we took a look at our species’ journey from sundial to the timing technology found in our newest PNT product, the GNSS Disciplined Oscillator, which can measure time with sub-nanosecond accuracy.

The History of Timekeeping

And in case you want to learn more about it: the GNSS Disciplined Oscillator (or GNSSDO, if you prefer) features the mosaic-T from Septentrio and the SiT5358 Super-TCXO oscillator from SiTime, providing ultra-precise timing output and allowing the reception of timing correction service AtomiChron® for accuracy better than 1ns.
