The 6 KB SRAM is tight: budget about 2 KB for stack and interrupt vectors, leaving 4 KB for data buffers. The 51 I/O give you plenty of GPIO for parallel displays, keypads, or sensor arrays.","metaTitle":"STM32F101R6T6A STM32F1 ARM Cortex-M3 MCU, 36 MHz","metaDescription":"STMicroelectronics STM32F101R6T6A 32-bit ARM Cortex-M3 MCU, 36 MHz, 32 KB Flash, 6 KB SRAM, 51 I/O, 64-LQFP, -40 to 85°C.

If your firmware fits in 32 KB Flash and 6 KB SRAM and you do not need USB or CAN, it is a drop-in replacement for cost reduction.

It is not a pin-compatible drop-in — it comes in a different package (UFQFPN-48) — but it is a functional alternative if you need lower power or USB."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F101R6T6A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F101R6T6A when reusing this data.
