 Hello, and welcome to this introduction to the STM32G0 microcontroller series. This short presentation describes the various lines available in the new STM32G0 series of entry-level MCUs for cost-sensitive applications. The STM32G0 microcontroller family is proposed in two lines. The value line is the baseline, offering a core set of features including a 12-bit ADC running up to the maximum speed of 64 MHz for a temperature range from minus 40 to 85 degrees Celsius. The access line is an upgrade of the value line, offering additional features over wider temperature and voltage ranges. For example, one can find integrated comparators, 12-bit DACs, integrated USB Type-C power delivery, and an HDMI CEC. This line also has a set of high-frequency timers and more capability for security-oriented solutions, and runs at a temperature range up to 125 degrees Celsius. The access line is available with or without embedded encryption. This table describes the differences between the value and access lines. This is the block diagram of the STM32G070 device from the value line. This is the block diagram of the STM32G071 device from the access line. This is the block diagram of the STM32G071 device from the access line with encryption features including a true random number generator, or RNG, and a 256-bit AES accelerator.
