The 13-channel 12-bit ADC samples at up to 1 µs per conversion — adequate for current-sense feedback in a BLDC motor controller or reading a few analog sensors, but not for high-speed data acquisition. ## Industrial temperature and active lifecycle The lifecycle status is Active, meaning ST continues to manufacture it with no announced end-of-life — no LTB risk for production programs starting today.","metaTitle":"STM32F042G6U6TR ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F042G6U6TR 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 32 KB Flash, 6 KB SRAM, USB and CAN in a 28-UFQFPN package.
