Replacement verdict
Compatible functional replacement candidate
The 10M16DAF256C8G and 10M16DAF256I7G are functionally equivalent Intel MAX 10 FPGA devices sharing identical logic density, package, and I/O configuration, with the primary distinction being the operating temperature grade. The commercial-grade C8G variant is suitable for standard temperature environments, while the industrial-grade I7G variant supports extended temperature ranges, making it the appropriate choice for harsh-environment applications. Both devices are drop-in compatible when thermal requirements are properly matched to the target application.

Frequently asked questions
What are the 10M16DAF256C8G and 10M16DAF256I7G devices?
Both are Intel (formerly Altera) MAX 10 family field-programmable gate arrays (FPGAs) in a 256-ball FineLine BGA (FBGA) package. They share the same 16,000 logic elements (LEs) density, integrated analog-to-digital converter (ADC) blocks, and non-volatile flash configuration. The suffix difference indicates the operating temperature grade: C8G denotes commercial temperature range with speed grade 8, while I7G denotes industrial temperature range with speed grade 7.
What is the difference between the C8G and I7G suffixes on these MAX 10 FPGAs?
The C8G suffix indicates a commercial temperature grade (typically 0°C to 85°C junction temperature) and speed grade 8. The I7G suffix indicates an industrial temperature grade (typically -40°C to 100°C junction temperature) and speed grade 7. Speed grade 7 is faster than speed grade 8, meaning the I7G device supports higher maximum operating frequencies for the same logic design.
Are the 10M16DAF256C8G and 10M16DAF256I7G pin-to-pin compatible?
Yes. Both devices use the same 256-ball FineLine BGA package with identical pinouts as defined in the Intel MAX 10 device pin-out files. The package footprint, ball assignments, and I/O bank locations are the same, allowing a common PCB layout. However, the industrial I7G version may have different timing closure requirements due to its faster speed grade.
Can the 10M16DAF256C8G be substituted with the 10M16DAF256I7G in an existing design?
Substitution is possible only after validating the design against the industrial temperature range and the faster speed grade. The I7G device is rated for -40°C to 100°C junction temperature, which covers the commercial range, and its speed grade 7 timing is faster than speed grade 8. The design must be re-timed and verified to ensure no hold-time violations occur with the faster device. Intel Quartus Prime software must be used to recompile the design targeting the I7G device.
What are the typical operating temperature ranges for the C8G and I7G grades?
Based on Intel MAX 10 datasheets, the commercial C8G grade supports a junction temperature range of 0°C to 85°C. The industrial I7G grade supports a junction temperature range of -40°C to 100°C. These ranges are specified for the device junction temperature, not ambient temperature, and proper thermal analysis is required for the target application.
Do both devices support the same configuration methods?
Yes. Both the 10M16DAF256C8G and 10M16DAF256I7G support identical configuration schemes, including internal configuration from the on-chip flash, active serial (AS), passive serial (PS), and JTAG configuration. The configuration flash memory (CFM) size and the available configuration interfaces are the same for both temperature grades and speed grades within the same device density.
What are the power supply requirements for these MAX 10 devices?
Both devices require the same nominal power supplies as specified in the Intel MAX 10 device datasheet: VCCINT (1.2 V core), VCCA (3.0 V or 3.3 V analog supply for ADC), and VCCIO for each I/O bank (supporting 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.0 V, or 3.3 V depending on the I/O standard). The industrial I7G grade may have slightly different power supply tolerance or decoupling requirements under extreme temperatures, which should be verified in the datasheet.
Which device is more suitable for automotive or industrial applications?
The 10M16DAF256I7G is more suitable for industrial and automotive applications because its industrial temperature grade supports -40°C to 100°C junction temperature. The 10M16DAF256C8G commercial grade is limited to 0°C to 85°C junction temperature and is intended for consumer and commercial applications. Automotive-grade variants may have additional qualification requirements not covered by the standard industrial grade.
