The 4 KB RAM is organized as 4K x 8; if your application needs a large frame buffer or multiple DMA buffers, budget carefully. The Flash is 16K x 8, enough for a modest application with a few peripheral drivers. ## Industrial temperature and active lifecycle The 23 I/O lines in a 28-pin package leave a high ratio of usable pins to package size — useful when you need several sensor inputs and a PWM output in a small footprint.","metaTitle":"STM32F031G4U6TR 32-bit ARM Cortex-M0 MCU, 48 MHz","metaDescription":"STMicroelectronics STM32F031G4U6TR 32-bit ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash, 4 KB RAM, 23 I/O, -40 to 85°C, 28-UFQFPN.
