The exposed paddle is not present on this package — all dissipation goes through the leads, so thermal budget is limited. The 1.65 V to 1.95 V supply on the VDD pins means the decoupling caps should be 100 nF per pin pair plus a bulk 4.7 µF or 10 µF on the 1.8 V plane; do not share this rail with a 3.3 V peripheral supply without a level translator. ## 51 I/O and CANbus — industrial and automotive-adjacent connectivity The HDMI-CEC interface is a niche addition useful for consumer AV equipment. ST lists the STM32F378RCT6 as Active. The base product number STM32F378 sits in the STM32F3 series, which remains a current portfolio line. The 64-LQFP package is a common footprint across several STM32F3 density variants, so a pin-compatible drop-in to a higher Flash or RAM sibling is possible without a board spin if the firmware scales.","metaTitle":"STM32F378RCT6 ARM Cortex-M4F MCU, 72 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F378RCT6 32-bit MCU with Cortex-M4F FPU, 72 MHz, 256 KB Flash, 32K x 8 RAM, 16+21 ADC channels, 3 DACs, 64-LQFP.

The STM32F378 adds the floating-point unit for DSP and math-heavy tasks, and its ADC channel mix differs — 16x12-bit plus 21x16-bit versus the STM32F373's 1x12-bit plus 3x16-bit plus 1x16-bit sigma-delta.

ST's ST-Link/V2 or a third-party debug probe (J-Link, DAPLink) connects to the 4-pin SWD header. The internal bootloader also supports USART1, USART2, and CAN for serial programming. STM32CubeProgrammer or the IDE (STM32CubeIDE, Keil, IAR) handles flash loading and debug."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F378RCT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F378RCT6 when reusing this data.
