Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF36094GFZV is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 64-LQFP (10x10) surface mount package to ensure PCB-level compatibility without layout modifications.
• Memory Configuration: Program memory must be 32KB FLASH with 2K x 8 RAM to maintain firmware compatibility and system functionality.
• Connectivity & Peripherals: I2C and SCI interfaces, along with LVD, POR, PWM, and WDT peripherals, are essential for system integration.
• Supply Voltage Range: The substitute must operate within or encompass the 3V to 5.5V supply range.
• Operating Temperature Range: The substitute must support the required operating temperature window.

The MC9S08MM32AVLH qualifies as a substitute based on matching package, memory size, RAM capacity, connectivity options, and peripheral set. However, architectural differences (8-bit vs. 16-bit core) and performance characteristics (48MHz vs. 20MHz) require firmware and timing validation during integration.

Parameter Comparison

Engineering Selection Recommendations

The MC9S08MM32AVLH is an active product with current manufacturing support, addressing the obsolescence status of the DF36094GFZV. Both devices share identical package geometry (64-LQFP 10x10), program memory capacity (32KB FLASH), and RAM configuration (2K x 8), enabling direct socket compatibility at the PCB level.

Key considerations for selection:

• Product Lifecycle: The MC9S08MM32AVLH is active and supported by Freescale Semiconductor, ensuring long-term availability and supply chain stability compared to the obsolete DF36094GFZV.
• Compliance: The DF36094GFZV is ROHS3 compliant. Verify RoHS compliance status of the MC9S08MM32AVLH with the supplier before final selection.
• Voltage Supply Range: The MC9S08MM32AVLH operates at 1.8V to 3.6V, which does not fully encompass the original 3V to 5.5V range. System power supply design must be validated to ensure compatibility.
• Architectural Differences: The shift from 16-bit to 8-bit core architecture requires firmware assessment and potential code modifications. The higher clock speed (48MHz vs. 20MHz) may affect timing-sensitive operations.

Frequently Asked Questions (FAQ)

Q: Can the MC9S08MM32AVLH be used as a direct drop-in replacement for the DF36094GFZV?

A: Both devices use the 64-LQFP (10x10) package, enabling physical and electrical socket compatibility. However, firmware validation is required due to core architecture differences (16-bit vs. 8-bit) and instruction set variations between the H8/300H and S08 processors.

Q: What are the main differences between these two microcontrollers?

A: The DF36094GFZV is a 16-bit H8/300H processor operating at 20MHz with a 3V to 5.5V supply range. The MC9S08MM32AVLH is an 8-bit S08 processor operating at 48MHz with a 1.8V to 3.6V supply range. Both share 32KB FLASH, 2KB RAM, and identical package dimensions. The MC9S08MM32AVLH includes SPI connectivity and integrated D/A conversion not present in the original part.

Q: Is the voltage supply range compatible?

A: The MC9S08MM32AVLH operates at 1.8V to 3.6V, which overlaps with but does not fully cover the original 3V to 5.5V range. If the system requires operation above 3.6V, the MC9S08MM32AVLH is not suitable. Verify system power supply specifications before selection.

Q: Are the I/O pin counts compatible?

A: The DF36094GFZV provides 31 I/O pins, while the MC9S08MM32AVLH provides 33 I/O pins. Both devices use the same 64-pin package, and the additional I/O pins on the MC9S08MM32AVLH do not create compatibility issues for existing designs.

Q: What is the operating temperature range difference?

A: The DF36094GFZV operates from -20°C to 75°C, while the MC9S08MM32AVLH operates from -40°C to 105°C. The MC9S08MM32AVLH supports a wider temperature range, providing greater flexibility for extended temperature applications.

Q: Do both devices support the same communication protocols?

A: Both devices support I2C and SCI connectivity. The MC9S08MM32AVLH additionally includes SPI, providing expanded communication options. Existing I2C and SCI implementations are compatible between the two devices.
