Nuvoton NuMaker-GestureAI-M55M1 module combines Cortex-M55 MCU with GC0308 camera for AI gesture control

NuMaker GestureAI M55M1

Back in November last year, we covered the launch of the NuMicro M55M1 MCU from Nuvoton, which combines an Arm Cortex-M55 core with an Ethos-U55 microNPU for on-device AI and gesture control. Now, they have released the NuMaker-GestureAI-M55M1, a development module based on that MCU for AI vision-related applications. This new board integrates the M55M1 MCU with a GC0308 CMOS image sensor, a digital microphone, and a microSD card slot for storing AI models. It is designed for applications such as gesture control, basic vision systems, and touchless interfaces. NuMaker-GestureAI-M55M1 specifications: MCU – Nuvoton NuMicro M55M1R2LJAE CPU – Cortex-M55 MCU @ 220 MHz Memory – 1.5 MB SRAM Storage – 2 MB Flash AI Accelerator – Arm Ethos-U55 micro-NPU @ 220 MHz Storage – MicroSD card slot (located on the back) for storing AI model files Camera – Integrated VGA GC0308 CMOS image sensor Audio – On-board digital microphone (DMIC) USB – […]

Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface

M3333 Series MCU

Nuvoton’s new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A,  Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols, completely offloading the CPU to run fluid, dynamic LED effects. It comes in two variants, the M3333 series and the M3334 series, with the latter adding a high-speed USB 2.0 OTG controller with an integrated PHY. NuMicro M3331 specifications: MCU core – Arm Cortex-M33 32-bit CPU @ 180 MHz with single-precision […]

Nuvoton introduces the first security chip based on OpenTitan open-source silicon Root of Trust

OpenTitan demo board Nuvoton open source security chip

Google has announced the start of the fabrication of a Nuvoton security chip featuring OpenTitan open-source silicon Root of Trust (RoT), the first such production-ready chip. It will soon be available in lowRISC’s Voyager 1 demo board, and later this year in Chromebooks and data centers. We first wrote about OpenTitan open-source Root of Trust (RoT) chips in 2020 as a collaboration between Google, Seagate, Nuvoton, Western Digital, lowRISC, as well as some other companies, projects, and universities that aimed at “building a transparent, high-quality reference design and integration guidelines for silicon root of trust (RoT) chips”.  OpenTitan itself reached commercial availability last year, after the first engineering samples were released in 2023, and Google now says the Nuvoton chip (yet to have a proper name) is the first production-ready OpenTitan chip. Hardware Root of Trust (RoT) are small secure microcontrollers that are the equivalent of Certificate Authorities (CAs) to […]

Nuvoton M2003 is a low-cost Arm Cortex-M23 MCU for AIoT and Industrial applications

Nuvoton NuMaker M2003FC development board

Nuvoton has recently launched the Nuvoton M2003 series of low-cost Arm Cortex-M23 microcontrollers which at the time of writing features M2003FC1AE and M2003XC1AE microcontrollers. Major features include a 32-bit hardware multiplier/divider, 32 KB of flash memory, 4 KB of SRAM, multiple communication interfaces (UARTs, I²C, USCI), analog peripherals (8-channel 12-bit ADC, 6-channel 16-bit PWM), and support for a wide voltage and temperature range. These features make this device useful for AIoT, industrial automation, smart homes, energy storage, and automotive electronics, and the company says the low-cost M2003 family offers a migration path from 8-bit to 32-bit designs. Feature-wise both the MCUs are the same and the only difference is in their package. The M2003FC1AE comes in a TSSOP20 package, whereas the M2003XC1AE comes in a QFN20 (3x3mm) package. The NuMaker-M2003FC development board is also offered for evaluation. Nuvoton M2003 series MCU specifications Device – Nuvoton M2003 series of MCUs M2003FC1AE […]

Nuvoton NuMicro M2L31 Arm Cortex-M23 MCU embeds up to 512KB high-durability ReRAM, 168KB SRAM

Nuvoton NuMaker-M2L31KI development board

Nuvoton NuMicro M2L31 is a family of Arm Cortex-M23 microcontrollers clocked up to 72 MHz, equipped with 64KB to 512KB high-durability ReRAM (Resistive Random-Access Memory) with fast write speeds, 40KB to 168KB SRAM. The microcontroller supports 1.71V to 3.6V operating voltage, can operate in the -40°C to 105°C temperature range, and offers a wide range of interfaces available through packages as small as WLCSP 25 (2.5 x 2.5 mm)  and up to LQFP128 (14 x 14 mm). Arm introduced the Cortex-M23 core in 2016 together with the Arm Cortex-M33 core, but while the latter is widely integrated in a large range of designs, we’ve seen fewer Cortex-M23 microcontrollers with some examples being Microchip SAML10/L11 (2018) and more recently, the Renesas RA0 family. Nuvoton adds another option with the Numicro M2L31 that also happens to integrates ReRAM non-volatile memory. Key Features: MCU core – Arm Cortex-M23 core running up to 72 […]
