Key Parameters

Substitute Part Grouping Explanation

Substitution of the STM32F372RCT6 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 frequency to ensure functional compatibility with existing firmware and timing-dependent operations.

Memory Configuration: The substitute part must provide 256KB of FLASH program memory and 32KB of RAM to maintain software compatibility and system memory requirements.

Electrical Specifications: The substitute part must operate within the 2V to 3.6V supply voltage range to ensure compatibility with existing power distribution networks and voltage regulation schemes.

Physical Package: The substitute part must use the 64-LQFP (10x10) surface mount package with 52 I/O pins to maintain PCB layout compatibility and pin assignment consistency.

Compliance & Environmental: The substitute part must maintain ROHS3 compliance, MSL 3 rating, and the same operating temperature range to satisfy regulatory requirements and environmental specifications.

The STM32F373RCT6 meets all these substitution criteria while offering enhanced data converter capabilities.

Parameter Comparison

Engineering Selection Recommendations

The STM32F373RCT6 serves as a direct functional substitute for the obsolete STM32F372RCT6. Both devices share identical core architecture, memory configuration, I/O count, package format, and electrical specifications. The STM32F373RCT6 maintains full compatibility with existing PCB layouts, firmware implementations, and system designs developed for the STM32F372RCT6.

The primary distinction between these parts lies in enhanced analog signal processing capabilities. The STM32F373RCT6 provides three 16-bit analog-to-digital converters and three 12-bit digital-to-analog converters, compared to the single 16-bit ADC and single 12-bit DAC in the STM32F372RCT6. This enhancement does not introduce incompatibility; applications utilizing only the base analog functionality of the STM32F372RCT6 operate identically on the STM32F373RCT6.

The STM32F373RCT6 carries Active product status with substantial inventory availability (51,228 units), ensuring long-term supply continuity. Both devices maintain ROHS3 compliance and identical MSL 3 ratings, satisfying regulatory and environmental requirements. The STM32F373RCT6 is supplied in Tray packaging, consistent with standard production and distribution practices.

Frequently Asked Questions (FAQ)

Q: Can the STM32F373RCT6 replace the STM32F372RCT6 in existing designs without PCB modifications?

A: Yes. Both devices use the 64-LQFP (10x10) package with identical pin assignments and 52 I/O pins. No PCB layout changes are required for direct substitution.

Q: Are the firmware and software implementations compatible between STM32F372RCT6 and STM32F373RCT6?

A: Yes. Both devices feature identical ARM® Cortex®-M4 core architecture, 72MHz clock speed, 256KB FLASH memory, and 32KB RAM. Existing firmware compiled for the STM32F372RCT6 executes on the STM32F373RCT6 without modification.

Q: What is the significance of the enhanced data converters in the STM32F373RCT6?

A: The STM32F373RCT6 provides three 16-bit ADCs and three 12-bit DACs versus one of each in the STM32F372RCT6. This enhancement expands analog signal processing capability but does not affect applications using only the base converter functionality.

Q: Do both parts operate within the same voltage supply range?

A: Yes. Both the STM32F372RCT6 and STM32F373RCT6 operate within the 2V to 3.6V supply voltage range, ensuring compatibility with existing power distribution networks.
