Frequently asked questions
What are the key differences between the 10M16DCF484C8G and the 10M16DAF256C8G?
The primary differences are package type, pin count, and I/O availability. The 10M16DCF484C8G is offered in a 484-pin FineLine BGA (FBGA) package, while the 10M16DAF256C8G uses a 256-pin FineLine BGA package. Both devices share the same 16,000-logic-element density and C8 speed grade, but the larger 484-pin package provides more user I/O pins than the 256-pin variant.
Are the 10M16DCF484C8G and 10M16DAF256C8G functionally identical in terms of logic capacity?
Yes. Both devices belong to the Intel (Altera) MAX 10 family and have the same 16,000 logic elements (LEs), 5,888 Kbits of M9K embedded memory, and 288 embedded 18x18 multipliers. The core logic architecture is identical; only the package and its associated pinout differ.
Can the 10M16DCF484C8G be used as a drop-in replacement for the 10M16DAF256C8G?
No. The two devices have different package footprints (484-pin FBGA vs 256-pin FBGA) and different pin counts, so they are not pin-to-pin compatible. A direct drop-in replacement is not possible without a PCB redesign.
Do both devices support the same configuration methods, such as internal configuration flash?
Yes. Both the 10M16DCF484C8G and 10M16DAF256C8G are MAX 10 devices featuring dual configuration flash memory, allowing them to be configured via internal flash, JTAG, or external configuration sources. The configuration architecture is identical across both packages.
What is the operating temperature range for the 10M16DCF484C8G and 10M16DAF256C8G?
Both devices are specified for commercial temperature operation, typically 0°C to 85°C junction temperature (TJ), as indicated by the C8 speed grade suffix. Industrial and automotive temperature variants exist in the MAX 10 family but are denoted by different suffixes.
Which device offers more user I/O pins, the 10M16DCF484C8G or the 10M16DAF256C8G?
The 10M16DCF484C8G offers more user I/O pins due to its larger 484-pin FBGA package. The 10M16DAF256C8G, with its 256-pin FBGA package, provides fewer user I/O pins. Exact I/O counts should be verified in the respective Intel MAX 10 device pin-out files.
Are both devices RoHS compliant and lead-free?
Yes. Both the 10M16DCF484C8G and 10M16DAF256C8G are offered in RoHS-compliant, lead-free packages as standard from Intel and authorized distributors. The "G" suffix in both part numbers indicates RoHS compliance and lead-free construction.
Do both devices require the same power supply voltages?
Yes. Both devices operate from the same MAX 10 power supply rails, including VCCINT (1.2 V), VCCA (2.5 V or 3.0 V), and VCCIO (1.2 V to 3.3 V depending on I/O standard). The power requirements are determined by the silicon die, which is identical across both packages.
