Replacement verdict
Compatible functional replacement candidate
The 10M25DAF484C8G and 10M25DCF484I7G are both Intel MAX 10 FPGA devices sharing the same 25K logic element density and 484-pin FBGA package, making them functionally interchangeable in many designs. However, the 10M25DCF484I7G offers a faster speed grade and a wider industrial temperature range, while the 10M25DAF484C8G provides lower power consumption with its automotive-grade rating. Designers should validate timing closure, power budget, and thermal requirements before substituting one for the other.

Frequently asked questions
What are the 10M25DAF484C8G and 10M25DCF484I7G devices?
Both are Intel (formerly Altera) MAX 10 field-programmable gate arrays (FPGAs) in the 484-pin FineLine BGA (FBGA) package. The 10M25DAF484C8G is a dual-supply, commercial-grade (0°C to 85°C junction) device with speed grade 8. The 10M25DCF484I7G is a single-supply, industrial-grade (-40°C to 100°C junction) device with speed grade 7. Both feature 25,000 logic elements (LEs) and belong to the MAX 10 family, which integrates non-volatile flash configuration memory.
What is the difference between the "DA" and "DC" suffixes in these part numbers?
The "DA" in 10M25DAF484C8G indicates a dual-supply voltage option (1.2 V core and 2.5 V I/O, or similar dual-rail configuration). The "DC" in 10M25DCF484I7G indicates a single-supply voltage option (3.3 V or 1.2 V single rail, depending on configuration). This difference affects power supply design, external component count, and power sequencing requirements.
Can the 10M25DAF484C8G and 10M25DCF484I7G be used interchangeably in the same design?
No, they are not directly interchangeable. The dual-supply (DA) and single-supply (DC) variants have different power rail requirements and pinout definitions for supply pins. Additionally, the speed grades (8 vs. 7) and temperature grades (commercial vs. industrial) differ, which affects timing closure and operating environment. A redesign of the power delivery network and timing analysis is required before substitution.
What are the operating temperature ranges for these two FPGAs?
The 10M25DAF484C8G is rated for commercial operation with a junction temperature (Tj) range of 0°C to 85°C. The 10M25DCF484I7G is rated for industrial operation with a junction temperature range of -40°C to 100°C. The industrial-grade device is suitable for harsh environments, while the commercial-grade device is intended for controlled environments.
What is the logic capacity and package of these devices?
Both devices provide 25,000 logic elements (LEs) and are housed in a 484-pin FineLine BGA (FBGA) package with a 0.8 mm ball pitch. They also include embedded memory blocks, DSP blocks, and analog-to-digital converter (ADC) blocks as part of the MAX 10 architecture. The package footprint is identical, but supply pin assignments differ between the DA and DC variants.
Which device is faster, the 10M25DAF484C8G or the 10M25DCF484I7G?
The 10M25DCF484I7G has a faster speed grade (7) compared to the 10M25DAF484C8G (speed grade 8). In Intel FPGA nomenclature, a lower speed grade number indicates faster performance. Therefore, the 10M25DCF484I7G offers shorter propagation delays and higher maximum operating frequencies, but this must be validated against the specific design's timing constraints.
Do both devices support instant-on configuration and flash memory integration?
Yes, both are MAX 10 FPGAs, which feature integrated non-volatile flash memory for instant-on configuration. They support single-chip configuration without an external configuration device. However, the dual-supply (DA) and single-supply (DC) variants may have different configuration voltage requirements and flash memory access timing, which should be verified in the respective datasheets.
What are the typical applications for each device?
The 10M25DAF484C8G (commercial, dual-supply) is typically used in consumer electronics, industrial control, and communication systems where cost and board space are optimized with dual-rail power. The 10M25DCF484I7G (industrial, single-supply, faster speed grade) is suited for automotive, industrial automation, and outdoor equipment requiring wide temperature operation and simplified power design. Application suitability must be confirmed against the specific system requirements.
