The 128K x 8 SRAM covers the stack, heap, and double-buffered ADC or display frames. ## Connectivity and I/O — what is on the pins The STM32F411RET6TR brings out 50 I/Os from the 64-LQFP package, with connectivity options that cover most embedded scenarios: I²C for sensors and EEPROMs, SPI for displays and ADCs, UART/USART for RS-232 or RS-485 transceivers, USB OTG for host/device mode, and SDIO for external Flash or SD cards. For production BOMs, this means you can qualify the part into a new design without planning a near-term spin for obsolescence. ## Package and mounting — 64-LQFP footprint notes The 64-LQFP (10x10 mm body) is a common fine-pitch package with 0.5 mm lead pitch. Surface-mount reflow per IPC/JEDEC J-STD-020.","metaTitle":"STM32F411RET6TR ARM Cortex-M4 MCU, 100 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F411RET6TR 32-bit ARM Cortex-M4 MCU, 100 MHz core, 512 KB Flash, 128K x 8 RAM, 50 I/O, 64-LQFP.
