ST Rolls Out New Series of STM32 Microcontrollers, Dubbed STM32G0

STMicroelectronics Lower Power Consumption and Large Memory Density in Low-Pin-Count Packages Create Compact Efficient Platform for Smart Connected Objects

STMicroelectronics expands its portfolio of top ArmCortex-M-core MCUs to more further cover key embedded-market segments, rolls out STM32G0 microcontrollers (MCUs) to the STM32* family.

The new G0 series targets entry-level applications that require greater energy efficiency, functionality, security, and value, in a smaller footprint.

Extremely Flexible Packaging And Memory Options Enable Designers:

  • To do more within less space, and save cost.
  • A new power-distribution architecture reduces external power and ground connections to just a single pair of pins, allowing more of the package pins — a precious resource in many embedded projects — to be allocated for user connectivity.
  • In addition, ST is making large memory densities available in small and economical low-pin-count packages.
  • On top of this, the new generation features power-saving innovations that trim consumption close to that of specialized ultra-low-power devices.
  • To provide robust security for today’s connected devices, the STM32G0 series introduces a variety of hardware-based features including memory protection to support secure boot.
  • Some devices in the series add to these features an AES-256 hardware cryptographic accelerator with a true random number generator (TRNG) to aid encryption.

Another valuable feature that anticipates a growing need is support for the latest USB Type-C specifications that allow easy, high-speed connectivity and battery charging, including Power Delivery version 3.0.

The STM32G0 series is based on the Arm Cortex-M0+ core, which is conceived to deliver sharp performance within a tight power budget. It targets fast-evolving products in the connected world, including smartphones, smart kitchen equipment, and appliances, air conditioning, consumer or industrial motor controls, advanced user interfaces, IoT devices, rechargeable connected devices, drones, lighting systems, and more.

Additional Info and Nuggets Include

  • Added STM32G0 MCUs help designers reduce the physical size and bill of materials for next-generation products, at the same time as boosting performance and functionality.
  • The maximum CPU frequency of 64MHz permits high execution speeds, compared to typical entry-level MCUs. On the other hand, extremely flexible clock configuration allows users to tailor performance within the available power budget.
  • STM32G0 MCUs comes in 8-pin, enabling developers to easily upgrade aging 8-bit MCU designs, to 100-pin. Flash from 16KByte to 512KByte, with 512KByte available in packages as small as 32-pin, enables more sophisticated applications on small, low-cost products.
  • Moreover, peripherals are upgraded to enhance performance, speed, and accuracy. The devices feature a 12-bit 2.5MSPS ADC, with hardware oversampling for 16-bit precision. There is also a 2-channel DAC, fast comparators, and high-accuracy timers with 7.8ns resolution.

The STM32G0 series is extremely efficient, running at less than 100µA/MHz in run mode, and provides multiple reduced-power operating modes to save energy and extend battery runtimes. Devices draw as little as 3-8µA in stop mode with the real-time clock (RTC) running, and just 500nA in standby with RTC (all at 3.0V, 25°C).

Availability and Pricing:

ST is planning several STM32G0 lines, including the STM32G071 and similar STM32G081 with hardware cryptographic enhancement. There are also Value Line STM32G070 devices for mass-market applications. Pricing starts from $0.69 for the STM32G070CBT6 Value Line MCU in a 48-pin package, with 128KByte Flash, for orders of 10,000 pieces.
