Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M30845FHGP#U3 are identified based on the following critical parameters that determine functional and physical compatibility:

Primary Substitution Criteria:

• Package compatibility: 144-LQFP (20x20) surface mount form factor
• Voltage supply range: 3V ~ 5.5V operation
• Program memory capacity: Minimum 384KB FLASH
• RAM capacity: Minimum 24K x 8
• Core architecture: 16/32-bit or 32-bit processor
• Operating temperature range: Support for -40°C ~ 85°C minimum
• Connectivity interfaces: CANbus and UART/USART support
• Peripheral integration: DMA, PWM, and WDT functionality

Substitution Logic: Parts are grouped as substitutes when they maintain electrical compatibility within the specified voltage and temperature ranges, support identical or enhanced connectivity and peripheral features, and are housed in the same or compatible package footprint. Enhanced specifications (higher clock speed, increased memory, extended temperature range, or additional peripherals) do not disqualify a part from substitution eligibility, provided core functionality is preserved or exceeded.

Engineering Selection Recommendations

M30875FHAGP#U3 (Renesas Electronics Corporation)

The M30875FHAGP#U3 is the primary equivalent substitute for the M30845FHGP#U3. Both devices share identical core specifications: M32C/80 processor architecture, 16/32-bit core size, 32MHz clock speed, 384KB FLASH program memory, 24KB RAM, and 3V to 5.5V supply voltage range. The M30875FHAGP#U3 maintains the same 144-LQFP (20x20) package footprint and operating temperature range of -40°C to 85°C. The substitute part offers enhanced connectivity with the addition of EBI/EMI and IrDA interfaces, and includes a power-on reset (POR) peripheral. The M30875FHAGP#U3 holds active product status, ensuring ongoing availability and support. Both parts are ROHS3 compliant with identical MSL ratings.

SPC560B50L5C6E0X (STMicroelectronics)

The SPC560B50L5C6E0X serves as a cross-manufacturer substitute option. This device maintains the same 144-LQFP (20x20) package and 3V to 5.5V supply voltage compatibility. The SPC560B50L5C6E0X provides enhanced specifications including a 32-bit single-core e200z0h processor operating at 64MHz (double the M30845FHGP#U3 speed), 512KB FLASH program memory (128KB additional), and 32KB RAM (8KB additional). The device supports an extended operating temperature range of -40°C to 125°C and includes automotive-grade qualification (AEC-Q100). Connectivity includes CANbus, I2C, LINbus, SCI, and SPI interfaces. The SPC560B50L5C6E0X is active in production status and ROHS3 compliant. This substitute is suitable for applications requiring higher processing capability and automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the M30875FHAGP#U3 be used as a direct replacement for the M30845FHGP#U3?

A: Yes. The M30875FHAGP#U3 is a direct equivalent substitute. Both devices feature identical core processor architecture (M32C/80), clock speed (32MHz), program memory (384KB FLASH), RAM (24KB), supply voltage range (3V to 5.5V), and package form factor (144-LQFP 20x20). The M30875FHAGP#U3 includes additional connectivity interfaces (EBI/EMI, IrDA) and a power-on reset peripheral, which do not affect compatibility. The primary advantage is active product status, ensuring continued availability.

Q: What are the key differences between the M30845FHGP#U3 and the SPC560B50L5C6E0X?

A: The SPC560B50L5C6E0X is a cross-manufacturer substitute from STMicroelectronics with enhanced specifications. Key differences include processor architecture (e200z0h versus M32C/80), clock speed (64MHz versus 32MHz), program memory (512KB versus 384KB), RAM (32KB versus 24KB), and operating temperature range (-40°C to 125°C versus -40°C to 85°C). The SPC560B50L5C6E0X includes automotive-grade qualification (AEC-Q100) and supports different connectivity protocols (LINbus, SCI, SPI versus IEBus, IrDA). Both devices maintain the same 144-LQFP package footprint and 3V to 5.5V supply voltage compatibility.

Q: Are all substitute parts housed in the same package?

A: Yes. The M30845FHGP#U3, M30875FHAGP#U3, and SPC560B50L5C6E0X are all housed in the 144-LQFP (20x20) surface mount package. This ensures identical PCB footprint compatibility and mounting requirements.

Q: Do all substitute parts support CANbus connectivity?

A: Yes. All three parts—M30845FHGP#U3, M30875FHAGP#U3, and SPC560B50L5C6E0X—include integrated CANbus connectivity. This is a core requirement for substitution eligibility in this product category.

Q: What is the significance of product status (Obsolete versus Active)?

A: Product status indicates availability and manufacturer support. The M30845FHGP#U3 is classified as obsolete, meaning Renesas Electronics Corporation has discontinued production and support. The M30875FHAGP#U3 and SPC560B50L5C6E0X are both active products, ensuring ongoing manufacturing, technical support, and supply chain availability. For new designs or long-term production requirements, active-status parts are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The M30845FHGP#U3, M30875FHAGP#U3, and SPC560B50L5C6E0X are all ROHS3 compliant, meeting environmental and regulatory requirements for hazardous substance restrictions.

Q: What is the MSL rating, and is it consistent across all parts?

A: MSL (Moisture Sensitivity Level) rating 3 indicates the component requires controlled storage conditions with a maximum floor life of 168 hours at 30°C and 85% relative humidity after the moisture barrier bag is opened. All three parts share an identical MSL rating of 3 (168 Hours), ensuring consistent handling and storage requirements.
