Replacement verdict
Compatible functional replacement candidate
The 5CEFA2F23C7N is a viable functional replacement candidate for the 5CEFA7F23I7N only when reduced logic density and commercial temperature operation are acceptable. The 5CEFA7F23I7N offers significantly higher logic capacity and industrial temperature qualification, making it the more capable device. Designers must validate resource utilization, timing closure, and thermal requirements before substituting the lower-density commercial-grade part in place of the higher-density industrial-grade FPGA.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA7F23I7N | 5CEFA2F23C7N | Why it matters |
|---|---|---|---|
| Logic Elements (LE) | 150000 | 25000 | Logic element count determines the amount of programmable logic available for implementing user designs; a large mismatch means the two devices are not functionally interchangeable for complex designs. |
| Total RAM Bits | 7880704 | 1953792 | Embedded memory capacity affects the ability to store data, buffers, and firmware on-chip; designs requiring large memory cannot be ported to the smaller device. |
| Number of I/Os | 480 | 480 | I/O count determines how many external signals the device can interface with; matching I/O counts support similar board-level connectivity. |
| Operating Temperature Range | -40°C to 100°C (TJ) | 0°C to 85°C (TJ) | Industrial-grade temperature range versus commercial-grade affects suitability for harsh environments and reliability in automotive or industrial applications. |
| Speed Grade | 7 (Fastest) | 7 (Fastest) | Speed grade determines maximum operating frequency and timing closure; identical speed grades simplify timing migration between devices. |
| Package / Case | FBGA-484 | FBGA-484 | Package compatibility is essential for drop-in replacement on an existing PCB; identical packages allow the same footprint to be reused. |
| Supply Voltage | 1.07V to 1.13V (Core) | 1.07V to 1.13V (Core) | Core voltage must match the board power design; identical voltage requirements allow shared power delivery networks. |
| Number of Logic Array Blocks (LABs) | 5640 | 943 | LAB count reflects the granularity of logic resources; a large difference indicates significantly different capacity for implementing complex functions. |
| Embedded Multipliers (18x18) | 312 | 66 | Dedicated multipliers are critical for DSP, filtering, and arithmetic-intensive applications; fewer multipliers limit signal processing capability. |
| PLLs | 8 | 4 | Phase-locked loops provide clock synthesis and management; fewer PLLs restrict the number of independent clock domains a design can support. |

Frequently asked questions
What are the key differences between the 5CEFA7F23I7N and the 5CEFA2F23C7N?
The 5CEFA7F23I7N and 5CEFA2F23C7N are both Intel (formerly Altera) Cyclone V FPGAs in the same 484-pin FBGA package (F23). The primary differences are logic density, speed grade, and operating temperature range. The 5CEFA7F23I7N offers higher logic density (approximately 150K logic elements) and is rated for industrial temperature range (-40°C to 100°C junction), while the 5CEFA2F23C7N has lower logic density (approximately 25K logic elements) and is rated for commercial temperature range (0°C to 85°C junction). Both share the same package footprint but differ in internal resources and environmental ratings.
Are the 5CEFA7F23I7N and 5CEFA2F23C7N pin-to-pin compatible?
Yes, both devices are offered in the same 484-pin FBGA package (F23). However, pin-to-pin compatibility does not guarantee functional equivalence. The 5CEFA7F23I7N and 5CEFA2F23C7N have different logic densities and may have different I/O bank assignments or dedicated pin functions. A direct drop-in replacement requires verifying the pinout and I/O assignments against the respective device datasheets and pin-out files from Intel.
Can the 5CEFA2F23C7N be used as a substitute for the 5CEFA7F23I7N in an existing design?
Substitution is not recommended without thorough validation. The 5CEFA7F23I7N has significantly more logic elements, memory blocks, and DSP blocks than the 5CEFA2F23C7N. A design that utilizes resources exceeding the 5CEFA2F23C7N capacity will not fit. Additionally, the 5CEFA7F23I7N is industrial temperature rated while the 5CEFA2F23C7N is commercial temperature rated, so the substitution may not meet the original environmental requirements. The design must be recompiled and timing-closed for the smaller device.
What are the operating temperature ranges for the 5CEFA7F23I7N and 5CEFA2F23C7N?
The 5CEFA7F23I7N is specified for industrial temperature operation with a junction temperature range of -40°C to 100°C (I7 speed grade). The 5CEFA2F23C7N is specified for commercial temperature operation with a junction temperature range of 0°C to 85°C (C7 speed grade). These temperature ranges are defined in the Intel Cyclone V device datasheet and must be observed for reliable operation.
Do the 5CEFA7F23I7N and 5CEFA2F23C7N have the same speed grade?
No. The 5CEFA7F23I7N has a speed grade of 7 (I7), while the 5CEFA2F23C7N has a speed grade of 7 (C7). Although both are speed grade 7, the prefix letter indicates the temperature range: "I" for industrial and "C" for commercial. The actual timing performance may differ between industrial and commercial versions due to different operating conditions. Designers must use the correct timing model for the targeted device and temperature grade.
What logic density does each device offer?
According to Intel Cyclone V device specifications, the 5CEFA7F23I7N belongs to the A7 density tier with approximately 150,000 logic elements (LEs). The 5CEFA2F23C7N belongs to the A2 density tier with approximately 25,000 logic elements (LEs). This six-fold difference in logic capacity is the most significant functional distinction between the two devices and directly impacts the complexity of designs that can be implemented.
Are both devices RoHS compliant and lead-free?
Yes. Both the 5CEFA7F23I7N and 5CEFA2F23C7N are offered in RoHS-compliant, lead-free packages as standard products from Intel. The "N" suffix in both part numbers indicates lead-free (Pb-free) construction. Designers should still confirm the specific ordering code and environmental compliance documentation from Intel or authorized distributors such as DigiKey or Mouser for the exact revision purchased.
