Replacement verdict
Compatible functional replacement candidate
The 10M50DAF256C8G and 10M50DCF256C7G are both Intel MAX 10 FPGA devices in the same 256-pin FBGA package with identical logic density and feature set, making them functionally interchangeable in most designs. The primary distinction is speed grade and temperature range, so the 10M50DCF256C7G can serve as a drop-in replacement for the 10M50DAF256C8G provided the target application tolerates the faster speed grade and the narrower commercial temperature window.

Frequently asked questions
What are the key differences between the 10M50DAF256C8G and the 10M50DCF256C7G?
The primary differences are the speed grade and the operating temperature range. The 10M50DAF256C8G is a speed grade 8 device specified for commercial temperature range (0°C to 85°C junction). The 10M50DCF256C7G is a faster speed grade 7 device specified for commercial temperature range (0°C to 85°C junction). Both are Intel MAX 10 FPGA devices with 50,000 logic elements in a 256-pin FineLine BGA (FBGA) package.
Are the 10M50DAF256C8G and 10M50DCF256C7G pin-to-pin compatible?
Yes. Both devices are offered in the same 256-pin FineLine BGA (FBGA) package with identical pinouts as defined by Intel MAX 10 device pin-out specifications. However, designers must verify that the faster speed grade of the 10M50DCF256C7G does not introduce signal integrity or timing issues in the target design.
Can the 10M50DAF256C8G be replaced by the 10M50DCF256C7G in an existing design?
In many cases yes, because the 10M50DCF256C7G is a faster speed grade (7 vs. 8) in the same package and temperature range. However, a direct substitution requires timing analysis to confirm that the faster device does not violate hold-time or other timing constraints, and that power consumption remains within the board's thermal and electrical limits. Always validate against the Intel MAX 10 device datasheet and your design's timing report.
What is the logic capacity of the 10M50DAF256C8G and 10M50DCF256C7G?
Both devices feature 50,000 logic elements (LEs), 1,638 Kbits of M9K embedded memory, and 288 18x18 multiplier blocks, as specified in the Intel MAX 10 device family datasheet. They also include integrated analog-to-digital converter (ADC) blocks and flash memory for configuration.
Do both devices support the same configuration methods?
Yes. Both the 10M50DAF256C8G and 10M50DCF256C7G are MAX 10 FPGA devices with integrated flash configuration memory. They support internal configuration from the on-chip flash, as well as external configuration via JTAG, and they can be used in dual-configuration mode. Refer to the Intel MAX 10 FPGA Configuration User Guide for detailed methods.
What is the operating temperature range for these two devices?
Both the 10M50DAF256C8G and the 10M50DCF256C7G are specified for the commercial temperature range, with a junction temperature (Tj) of 0°C to 85°C. The "C" in the part number indicates commercial grade. Industrial-grade versions would carry an "I" designator and a different temperature range.
Which device is faster, the 10M50DAF256C8G or the 10M50DCF256C7G?
The 10M50DCF256C7G is faster. In Intel FPGA speed grade nomenclature, a lower number indicates a faster speed grade. Speed grade 7 is faster than speed grade 8, resulting in shorter propagation delays and higher maximum operating frequencies for the 10M50DCF256C7G compared to the 10M50DAF256C8G.
Are the 10M50DAF256C8G and 10M50DCF256C7G RoHS compliant?
Yes. Both devices are offered in RoHS-compliant packages as stated in Intel's product material declarations and distributor documentation. The 256-pin FBGA package is lead-free and meets RoHS requirements. Always confirm the specific ordering code and latest compliance documentation from Intel or authorized distributors.
