Replacement verdict

Compatible functional replacement candidate

The 10M04DCF256C8G and 10M04DCF256C7G are functionally equivalent MAX 10 FPGA devices sharing identical logic density, package, and I/O configuration, with the only distinction being the speed grade. The C8G variant offers a faster core speed grade, while the C7G provides a lower-speed, potentially lower-cost alternative. Both devices are drop-in compatible in terms of footprint and pinout, making the C7G a viable substitute for the C8G in designs where the higher speed grade is not timing-critical.

Key electrical and mechanical differences between the two devices

Parameter 10M04DCF256C8G 10M04DCF256C7G Why it matters
Speed Grade 8 7 The speed grade determines the maximum operating frequency and timing performance; a lower number indicates a faster grade, so the C7G device can run at higher clock rates than the C8G.
Family MAX 10 MAX 10 Both devices belong to the same FPGA family, ensuring compatible architecture, toolchain support, and IP availability.
Logic Elements (LEs) 4,000 4,000 Logic element count defines the available programmable logic capacity; identical counts mean equivalent logic density for design implementation.
Package 256-pin FBGA 256-pin FBGA Package type and pin count must match for physical board compatibility and footprint interchangeability.
Operating Temperature Range 0°C to 85°C (Commercial) 0°C to 85°C (Commercial) The temperature range determines the environments in which the device can reliably operate; both are commercial-grade.
Supply Voltage (Core) 1.2 V 1.2 V Core supply voltage must match the board power design; identical values ensure the same power delivery scheme can be used.
Embedded Memory 189 Kbits 189 Kbits On-chip memory capacity affects the ability to store data, buffers, and configuration; identical capacity means equivalent memory resources.
Configuration Method Internal configuration flash Internal configuration flash Both devices feature integrated configuration flash, allowing single-chip operation without external configuration memory.
Maximum Operating Frequency Lower (grade 8) Higher (grade 7) The speed grade directly affects the maximum achievable clock frequency; the C7G supports faster timing closure for performance-critical designs.

Frequently asked questions

What are the 10M04DCF256C8G and 10M04DCF256C7G devices?

Both are Intel (formerly Altera) MAX 10 field-programmable gate arrays (FPGAs) in the same 256-ball FineLine BGA (FBGA) package. They share the 10M04 density grade, which provides 4,000 logic elements (LEs), and both are specified for commercial temperature operation. The only difference indicated by the ordering codes is the speed grade: C8G denotes speed grade 8, while C7G denotes speed grade 7.

What is the difference between the 10M04DCF256C8G and 10M04DCF256C7G?

The primary difference is the speed grade. The 10M04DCF256C8G is rated at speed grade 8, and the 10M04DCF256C7G is rated at speed grade 7. Speed grade 7 is the faster of the two, offering shorter propagation delays and higher maximum operating frequencies for the same logic implementation. Both parts use the same 10M04 die, 256-ball FBGA package, and commercial temperature range.

Are the 10M04DCF256C8G and 10M04DCF256C7G pin-compatible?

Yes. Both devices are offered in the same 256-ball FineLine BGA package with the same pinout and ball assignments for the 10M04 device density. This means they are footprint-compatible and can use the same PCB land pattern, provided the design meets the timing requirements of the selected speed grade.

Can the 10M04DCF256C8G and 10M04DCF256C7G be used interchangeably in a design?

They are not automatically interchangeable. Because the speed grades differ, timing closure must be re-verified. A design that meets timing with the faster C7G device may not meet timing with the slower C8G device. Conversely, a design closed for C8G will generally meet timing with C7G, but the designer must still confirm all timing constraints and I/O standards against the target device's datasheet.

What is the logic capacity of the 10M04DCF256C8G and 10M04DCF256C7G?

Both devices belong to the MAX 10 10M04 density family and provide 4,000 logic elements (LEs). They also include embedded memory blocks and user flash memory as defined in the Intel MAX 10 device family documentation. The logic capacity is identical because the difference between the two ordering codes is the speed grade, not the device density.

Do the 10M04DCF256C8G and 10M04DCF256C7G support the same configuration methods?

Yes. Both are MAX 10 devices and support the same configuration schemes defined for the MAX 10 family, including internal configuration from on-chip flash and external configuration options. Configuration method support is a function of the device family and density, not the speed grade, so both ordering codes share the same configuration capabilities.

Which speed grade should be selected, C7G or C8G?

Select the speed grade based on the timing requirements of the design. If the design requires the shortest delays and highest operating frequencies supported by the 10M04 density, the C7G (speed grade 7) is the faster option. If the design meets all timing constraints with speed grade 8, the C8G may be used. The choice must be validated with the Intel MAX 10 timing model and the specific device datasheet.

Are the 10M04DCF256C8G and 10M04DCF256C7G lead-free and RoHS compliant?

RoHS and lead-free status are determined by the specific ordering code and the manufacturer's product compliance documentation. Intel publishes product material declarations and environmental compliance information for MAX 10 devices. Designers should verify the exact ordering code against the current Intel product compliance data before making a compliance claim.
