Key Parameters

Substitute Part Grouping Explanation

Substitution of the M30624SPGP#U5C requires evaluation based on the following critical parameters:

Core Architecture & Processing Capability: The M16C/60 is a 16-bit processor. Substitute parts must support equivalent or superior processing capability and instruction set compatibility for firmware migration.

Memory Configuration: ROMless architecture with 20K x 8 RAM. Substitutes must maintain ROMless configuration and equivalent or greater RAM capacity.

Operating Voltage Range: Supply voltage 2.7V ~ 5.5V defines power domain compatibility. Substitutes must support overlapping or equivalent voltage ranges.

Package & Pin Count: 100-LQFP (14x14) with 50 I/O pins. Physical package compatibility is essential for PCB integration.

Peripheral Set & Connectivity: DMA, WDT, I2C, IEBus, UART/USART, and mixed-signal converters (A/D 26x10b, D/A 2x8b) define functional requirements.

Compliance & Certifications: RoHS3 compliance and MSL rating ensure environmental and manufacturing process compatibility.

The TMS320R2811PBKA from Texas Instruments is identified as a substitute based on shared ROMless architecture, equivalent RAM capacity (20K x 16), surface mount packaging (128-LQFP 14x14), and overlapping peripheral functionality (DMA, WDT, I2C, SCI, SPI, UART/USART).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The M30624SPGP#U5C is obsolete. The TMS320R2811PBKA is active production, ensuring long-term availability and supply chain stability.

Compliance & Certification: Both devices are RoHS3 compliant. The TMS320R2811PBKA carries AEC-Q100 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Moisture Sensitivity: The TMS320R2811PBKA has MSL rating 2 (1 Year) compared to MSL rating 3 (168 Hours) for the M30624SPGP#U5C, indicating superior moisture tolerance during storage and handling.

Voltage Supply Range Mismatch: The TMS320R2811PBKA operates at 1.81V ~ 2V, which does not overlap with the M30624SPGP#U5C supply range of 2.7V ~ 5.5V. This represents a critical incompatibility requiring power supply redesign or alternative component selection.

Package Footprint: Both devices use 14x14mm LQFP packages. The TMS320R2811PBKA uses 128-pin LQFP versus 100-pin LQFP for the M30624SPGP#U5C, requiring PCB layout modification.

Processing Capability: The TMS320R2811PBKA provides 32-bit processing at 150MHz versus 16-bit at 24MHz, offering significant performance headroom for legacy firmware migration.

Frequently Asked Questions (FAQ)

Q: Can the TMS320R2811PBKA directly replace the M30624SPGP#U5C?

A: Direct replacement is not feasible due to voltage supply range incompatibility (1.81V ~ 2V versus 2.7V ~ 5.5V), different pin counts (128 versus 100), and different package pin assignments. Firmware porting and PCB redesign are required.

Q: What are the key substitution criteria for ROMless microcontrollers?

A: Critical parameters include program memory type (ROMless architecture), RAM capacity and organization, voltage supply range compatibility, package form factor and pin count, peripheral set (DMA, WDT, communication interfaces), and operating temperature range.

Q: Does the TMS320R2811PBKA support the same communication protocols?

A: Both devices support I2C and UART/USART. The TMS320R2811PBKA adds CANbus, McBSP, and SPI connectivity. IEBus support on the M30624SPGP#U5C is not replicated on the substitute.

Q: What is the significance of MSL rating differences?

A: MSL rating 2 (1 Year) on the TMS320R2811PBKA provides extended shelf life and greater tolerance to moisture absorption compared to MSL rating 3 (168 Hours) on the M30624SPGP#U5C, reducing risk during component storage and assembly processes.

Q: Are there firmware compatibility considerations?

A: The M16C/60 16-bit instruction set is not compatible with the C28x 32-bit architecture. Firmware migration requires code porting and testing. The higher clock speed (150MHz versus 24MHz) may require timing adjustments in peripheral drivers.

Q: What does AEC-Q100 qualification indicate?

A: AEC-Q100 is an automotive industry qualification standard. The TMS320R2811PBKA meets automotive reliability and quality requirements, making it suitable for automotive applications where the M30624SPGP#U5C may not be qualified.
