8-bit Microcontrollers

As an industry leader in delivering the fastest speeds and lowest power, let us help solve your mixed-signal and low-latency embedded challenges. Our innovative, 8-bit microcontrollers (MCUs) are ideal for a broad range of IoT applications and beyond. By leveraging optimized analog and digital peripherals, flexible pin mapping, and high system clock speeds, our 8-bit MCUs allow you to do more in less time, for lower power, and with lower latency. Take advantage of our free tool set that includes an IDE, programmer, compiler, software development kit (SDK), and more, enabling you to evaluate, develop, debug and ultimately, get to market faster.

      1. Software and Tools

      8-bit Software Development

      Simplicity Studio is the core development environment designed to support the Silicon Labs IoT portfolio of 8-bit SoCs. It provides access to target device-specific web and SDK resources in the Launcher; software and hardware configuration tools; an integrated development environment (IDE) featuring industry-standard code editors, compilers and debuggers; and advanced, value-add tools for network analysis and code-correlated energy profiling.

      Silicon Labs offers an advanced 8-bit microcontroller studio, available at no charge to developers. These tools unlock the power and flexibility of the 8-bit 8051 microcontroller family. All C8051Fxxx families are supported by the 8-bit Studio. If your 8051 device does not appear in the 8-bit studio list, you can also use Simplicity Studio Software Suite.

      Simplicity Studio   Simplicity Studio is designed to make the development process easier, faster, and more efficient by providing designers with everything they need to complete their projects from initial concept to final product. The Simplicity Studio platform provides unified development support for EFM8 and 8051 SoCs, complete with wireless stacks.
      8-bit Microcontroller Studio   These tools help develop, download, and debug firmware to the 8051 8-bit MCU devices. Now includes an unlimited Keil® PK51 Professional Developer's Kit
      EFM8 IEC-60730 Class B Safety Software   The EFM8 IEC-60730 software package enables end products using the EFM8 MCUs to quickly comply with the IEC-60730 Class B standard.
