What sets this part apart in the STM32F0 lineup is the USB peripheral on a small-pin-count Cortex-M0. ## 16 KB Flash and 6K RAM — sizing the firmware budget 16 KB of Flash and 6 KB of SRAM constrain firmware and data buffers. STMicroelectronics lists the STM32F042K4T6TR as Active. ## Pin-compatible alternatives in the STM32F042 family The STM32F042K4T6TR is pin-compatible with other STM32F042Kx devices in the same 32-LQFP package.","metaTitle":"STM32F042K4T6TR ARM Cortex-M0 MCU, 48MHz, 16KB Flash","metaDescription":"STM32F042K4T6TR 32-bit ARM Cortex-M0 MCU from STMicroelectronics. 48MHz core, 16KB Flash, 6K x 8 RAM, USB & CAN.
