The STM32G070CBT6TR is an STMicroelectronics STM32G0-series microcontroller built around a 32-bit ARM Cortex-M0+ core clocked at 64 MHz. This is the Tape & Reel variant of the base STM32G070CBT6, intended for automated pick-and-place assembly.
128 KB Flash, 36 KB SRAM — sizing the firmware and data budget
128 KB of Flash is a comfortable fit for a moderate-complexity firmware image — think a bootloader plus an application layer with a few protocol stacks (I²C, SPI, UART, LINbus). The 36 KB SRAM gives room for multiple packet buffers, a modest RTOS heap, and real-time data acquisition from the 12-bit ADC without tight packing. If your application needs OTA update staging, budget about half the Flash for the secondary image slot; the remaining 64 KB still leaves space for a functional main image.
17×12b ADC and peripheral set — sensor and control node fit
With 17 analog input channels at 12-bit resolution, this MCU can handle multi-sensor acquisition (temperature, pressure, current sense) without an external multiplexer.
