Frequently asked questions
What are the 10M40DCF256A7G and 10M40DCF256I6G devices?
Both are Intel (formerly Altera) MAX 10 field-programmable gate arrays (FPGAs) in the same 256-ball FineLine BGA (FBGA) package. The 10M40DCF256A7G is specified for commercial temperature operation, while the 10M40DCF256I6G is specified for industrial temperature operation. Both are dual-configuration (CF) devices with 40,000 logic elements (LEs) and integrated analog-to-digital converter (ADC) blocks.
What is the difference between the 10M40DCF256A7G and 10M40DCF256I6G?
The primary difference is the temperature grade and speed grade. The 10M40DCF256A7G is a commercial-grade device with a speed grade of 7, while the 10M40DCF256I6G is an industrial-grade device with a speed grade of 6. The industrial version supports a wider operating temperature range, making it suitable for harsher environments, whereas the commercial version is intended for standard office or consumer environments.
Are the 10M40DCF256A7G and 10M40DCF256I6G pin-to-pin compatible?
Yes, both devices use the same 256-ball FBGA package with identical pinouts. This means they are pin-to-pin compatible, allowing a single PCB design to accommodate either device. However, the industrial-grade 10M40DCF256I6G may have different timing characteristics due to its speed grade, so timing analysis must be re-validated if substituting.
Can the 10M40DCF256A7G be substituted with the 10M40DCF256I6G in an existing design?
Substitution is possible only after verifying that the industrial temperature range and the different speed grade (6 vs. 7) meet the design's timing and environmental requirements. The 10M40DCF256I6G operates over a wider temperature range but may have slower maximum operating frequencies. Always consult the Intel MAX 10 device datasheet and perform timing analysis before substituting.
What are the operating temperature ranges for these devices?
The 10M40DCF256A7G (commercial grade) typically operates from 0°C to 85°C junction temperature (TJ). The 10M40DCF256I6G (industrial grade) typically operates from -40°C to 100°C junction temperature (TJ). These ranges are defined in the Intel MAX 10 device datasheet and must be respected for reliable operation.
Do both devices support dual configuration (CF) and integrated ADC?
Yes, both the 10M40DCF256A7G and 10M40DCF256I6G are dual-configuration (CF) MAX 10 devices, meaning they support both instant-on configuration from internal flash and user flash memory. They also include integrated 12-bit analog-to-digital converter (ADC) blocks, as per the MAX 10 FPGA family features.
What are the typical applications for each temperature grade?
The 10M40DCF256A7G (commercial) is typically used in consumer electronics, office equipment, and benign indoor environments. The 10M40DCF256I6G (industrial) is used in industrial automation, automotive infotainment, outdoor equipment, and other applications requiring operation over extended temperature ranges.
Where can I find verified technical data for these devices?
Verified technical data is available from the official Intel (Altera) MAX 10 FPGA device datasheet, as well as from authorized distributors such as DigiKey, Mouser, TTI, and Future Electronics. Always refer to the manufacturer's datasheet for the most accurate and up-to-date specifications.
