Key Parameters

Substitute Part Grouping Explanation

Substitution of the STM32F372CCT6 is determined by strict equivalence across the following critical parameters:

Core Architecture & Performance: The substitute part must feature an identical ARM® Cortex®-M4 core processor, 32-bit single-core configuration, and 72MHz operating speed to ensure software compatibility and performance parity.

Memory Configuration: Program memory must be 256KB FLASH with 32KB RAM to maintain firmware compatibility and system functionality without modification.

Electrical Specifications: Supply voltage range must remain 2V to 3.6V to ensure operation within the same power delivery constraints.

Connectivity & Peripherals: The substitute must provide identical connectivity interfaces (CANbus, I2C, IrDA, LINbus, SPI, UART/USART, USB) and peripheral support (DMA, I2S, POR, PWM, WDT) to maintain system integration without redesign.

Package & Mounting: The 48-LQFP (7x7) surface mount package is mandatory for PCB layout compatibility.

Environmental & Compliance: Operating temperature range of -40°C to 85°C and ROHS3 compliance must be maintained.

The STM32F373CCT6 meets all substitution criteria and is classified as an active product, providing production availability and long-term supply assurance.

Parameter Comparison

Engineering Selection Recommendations

The STM32F373CCT6 is the direct equivalent substitute for the STM32F372CCT6. Both devices share identical core architecture, memory configuration, electrical specifications, connectivity interfaces, and package specifications. The STM32F373CCT6 provides enhanced analog-to-digital converter capability (3x16b versus 1x16b) and digital-to-analog converter capability (3x12b versus 1x12b), representing a functional superset of the original part.

The critical distinction between these parts is product status: the STM32F372CCT6 is classified as obsolete, while the STM32F373CCT6 is active. This status difference ensures long-term availability, production support, and supply chain continuity for the substitute part.

Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production environments. The identical MSL rating of 3 (168 Hours) ensures equivalent moisture handling and storage protocols.

Selection of the STM32F373CCT6 as a substitute provides functional compatibility with the original design while securing access to an actively manufactured component with established supply channels.
