Microcontrollers (MCUs)

Microcontrollers (MCUs) control embedded applications with onboard flash and peripherals – bare-metal or with RTOS. We supply MCUs from Holtek, Nuvoton and others with package and second-source advice.

What matters when selecting

  • Core/architecture: 8-bit, 8051, Arm Cortex-M0/M4/M23/M33 or RISC-V
  • Flash & RAM: to match the firmware size
  • Peripherals: ADC, PWM, UART, SPI, I²C, USB, touch, LCD driver
  • Voltage & temperature: wide range; commercial to extended
  • Package: package type and pin count as the key selection criterion

Part of the category Semiconductors & ICs.

Frequently asked questions from developers and buyers

Which core suits my application?

8-bit for simple control, Cortex-M for more compute and connectivity. We advise by compute need and peripherals.

How much flash/RAM do I need?

It depends on firmware and stack. We choose with headroom so later extensions remain possible.

Which package?

Package type and pin count drive layout and manufacturing. A part often exists in several packages – we select the right variant.

Are second-source and long-term availability available?

Yes – we review alternatives and plan lifecycle/EOL with you. Request your project now
