Originating from the STM32F0 gene of the entry-level low-cost Cortex-M0 core launched in 2012, ST launched the new generation of entry-level low-cost Cortex-M0 + mainstream STM32G0 in 2018. It is known as the king of cost performance: high performance, low power consumption, and convenient and easy-to-use features make it an entry-level STM32 development tool.

 
 
 
   

STM32G0 key features

 
 
 
   

Compared with the F0 and L0 series, which are also based on the Arm Cortex M0+ core, the STM32G0 series is a more efficient microcontroller. Through optimized design and various detail settings, the design goals are achieved with the minimum BOM cost and maximum upgrade flexibility, making the investment worthwhile.  
 

▲ STM32G0 product portfolio
 
  EfficientBased on the ARM Cortex M0+ core and 64MHz main frequency, STM32G0 has the maximum number of I/Os, the best RAM/Flash ratio, and a minimum package of 8 pins; low power consumption (3µA in Stop mode, less than 100µA/MHz in run mode); 1% precision internal high-speed RC oscillator.  
  reliableSTM32G0 has low EMI, strong EMC, clock monitoring and 2 watchdogs. Flash comes with error checking and correction. The security features are perfect for IOT applications; hardware AES-256 encryption or new trusted storage area, firmware secure upgrade SFU/SFI firmware secure download.  
  Easy to useThanks to STM32CubeMX, HAL and LL libraries, STM32G0 can carry out intuitive graphical configuration development, maximize reuse and quickly bring to market.  
  lower costSTM32G0 strives to innovate for the benefit of customers. Up to 64pin package requires only 1 pair of power supplies; no external clock, no decoupling capacitor, smaller PCB, USB-C PD power supply, integrated transceiver, pull-up and pull-down resistors and digital BMC, and secure programming is implemented internally or by a third party.  
 

▲ STM32G0 reduces BOM cost
  higher performanceUp to 64 MHz/ 59 DMIPS, up to 142 CoreMark score, ARM Cortex-M0+ comes with a memory protection unit (MPU), and up to 12 channels of DMA can be flexibly configured.  
  Lower power consumptionSTM32G0 is a typical example of a perfect match between mainstream MCU and low power consumption requirements. It supports better low power consumption mode and the running power consumption is around 80μA/MHz. Low power consumption modes include sleep mode, STOP mode, STANDBY, SHUTDOWN, and VBAT modes, and the wake-up time only takes 14μs.  
  saferSTM32G0 integrates a variety of security features to prevent problems before they occur: firmware IP protection, private code protection, key storage, identity authentication, and secure firmware upgrade.  
 

▲STM32G0 supports a variety of smart peripherals
  Faster, more accurate analog and digital featuresSTM32G0 uses larger RAM to match Flash, integrates a timer frequency up to 128MHz resolution (<8ns), and has advanced control capabilities; a 12-bit ADC up to 2.5MSPS (0.4µs) can achieve 16-bit hardware oversampling; in addition, it also integrates 32Mbit/s SPI, 7 M baud/s USART, 1Mbit/s I²C and other common communication interfaces.
