Replacement verdict
Compatible functional replacement candidate
The 5CEFA4F23I7N and 5CEFA2M13C8N are both Intel (Altera) Cyclone V FPGAs sharing the same core architecture and logic cell family, making them functionally related candidates. However, they differ in logic density, package footprint, and operating temperature grade, so a direct drop-in substitution is not possible without design review. The 5CEFA4F23I7N offers higher logic capacity and industrial temperature support, while the 5CEFA2M13C8N provides a smaller package and commercial temperature range. Validation of logic utilization, board layout, and thermal requirements is required before considering either device as a replacement for the other.

Frequently asked questions
What are the key differences between the 5CEFA4F23I7N and the 5CEFA2M13C8N?
The 5CEFA4F23I7N is a Cyclone V FPGA with 49,000 logic elements, 308 embedded multipliers, and 3,880 Kbits of embedded memory in a 484-pin FBGA package, rated for industrial temperature range (I7). The 5CEFA2M13C8N is a Cyclone V FPGA with 25,000 logic elements, 150 embedded multipliers, and 1,960 Kbits of embedded memory in a 383-pin Micro FBGA package, rated for commercial temperature range (C8). The 5CEFA4F23I7N offers higher logic density, more memory, and a wider temperature range, while the 5CEFA2M13C8N provides a smaller package and lower power consumption for cost-sensitive commercial applications.
Are the 5CEFA4F23I7N and 5CEFA2M13C8N pin-to-pin compatible?
No. The 5CEFA4F23I7N uses a 484-pin FBGA package (23 mm x 23 mm), while the 5CEFA2M13C8N uses a 383-pin Micro FBGA package (13 mm x 13 mm). The different package sizes, pin counts, and ball maps make them physically and electrically incompatible for direct PCB replacement.
Can the 5CEFA2M13C8N be used as a direct substitute for the 5CEFA4F23I7N?
No. The 5CEFA2M13C8N has fewer logic elements (25,000 vs 49,000), fewer embedded multipliers (150 vs 308), less embedded memory (1,960 Kbits vs 3,880 Kbits), a different package (383-pin Micro FBGA vs 484-pin FBGA), and a commercial temperature grade (C8) versus the industrial grade (I7) of the 5CEFA4F23I7N. A direct substitution would require a complete redesign of the PCB and verification that the reduced resources meet the application requirements.
What are the operating temperature ranges for these two FPGAs?
The 5CEFA4F23I7N is rated for the industrial temperature range, typically -40°C to +100°C junction temperature (I7 grade). The 5CEFA2M13C8N is rated for the commercial temperature range, typically 0°C to +85°C junction temperature (C8 grade). The industrial-grade device is suitable for harsh environments, while the commercial-grade device is intended for controlled environments.
Which device consumes less power?
The 5CEFA2M13C8N generally consumes less power due to its smaller logic density (25,000 LE vs 49,000 LE), lower embedded memory, and commercial temperature grade. However, actual power consumption depends on the specific design, clock frequencies, and I/O usage. Altera/Intel PowerPlay Early Power Estimator tools should be used for accurate comparison in a given application.
Do both devices support the same configuration and transceiver options?
Both are Cyclone V FPGAs and share the same configuration schemes (active serial, passive serial, JTAG, etc.). However, the 5CEFA4F23I7N (F23 package) supports up to 6 transceivers at 3.125 Gbps, while the 5CEFA2M13C8N (M13 package) supports up to 2 transceivers at 3.125 Gbps. The number of available high-speed transceiver channels differs due to package and device variant.
What are the typical applications for each device?
The 5CEFA4F23I7N is typically used in industrial automation, motor control, medical imaging, and harsh-environment applications requiring higher logic density and industrial temperature support. The 5CEFA2M13C8N is commonly used in consumer electronics, portable devices, and cost-sensitive commercial applications where small package size and lower power are critical.
Are these devices RoHS compliant and lead-free?
Yes. Both the 5CEFA4F23I7N and 5CEFA2M13C8N are offered in RoHS-compliant, lead-free packages as standard from Intel (formerly Altera). However, customers should verify the specific ordering code and packaging options with the manufacturer or authorized distributor to confirm compliance for their production requirements.
