That saves board area versus a TQFP but demands a multi-layer PCB with microvias or blind vias to route the 55 I/O plus supply and ground. ST lists the STM32F051R8H6TR as Active. That means no last-time-buy clock is running, no end-of-life notice is pending, and the part flows through franchised distribution alongside the independent channel.","metaTitle":"STM32F051R8H6TR ARM Cortex-M0 MCU, 48 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F051R8H6TR 32-bit ARM Cortex-M0 MCU at 48 MHz with 64 KB Flash, 8 KB SRAM, 55 I/O, 64-UFBGA package.

The key difference is the package: the R8H6TR comes in a 64-UFBGA (5x5 mm) while the R8T6 uses a 64-pin LQFP. The BGA saves board area but requires a more complex PCB stack-up and assembly process compared to the LQFP's perimeter leads."},{"question":"How much flash memory does STM32F051R8H6TR have?","answer":"That is enough for moderate firmware stacks — control loops, sensor fusion, communication protocol handlers — but tight for complex GUI or over-the-air update staging without external memory."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F051R8H6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F051R8H6TR when reusing this data.
