5CSEBA4U19C8SN vs 5CSEBA2U19C8N

Both are Intel (formerly Altera) Cyclone V SE SoC FPGA devices in the 484-pin UBGA (U19) package with a C8 speed grade. The 5CSEBA2U19C8N is a Cyclone V SE SoC FPGA with 25,000 logic elements (LEs), while the 5CSEBA4U19C8SN is a Cyclone V SE SoC FPGA with 40,000 LEs. Both integrate a dual-core ARM Cortex-A9 hard processor system (HPS) alongside the FPGA fabric.

The 5CSEBA2U19C8N provides 25,000 LEs, whereas the 5CSEBA4U19C8SN provides 40,000 LEs. This difference affects available adaptive logic modules (ALMs), M10K memory blocks, and DSP resources, so designs requiring higher logic utilization should verify resource fit against the target device.

Both devices use the same 484-pin UBGA (U19) package, which provides an identical physical footprint and ball map for the package. However, pin-compatibility at the package level does not guarantee that all I/O assignments, transceiver channels, or HPS peripherals are functionally identical between the two density variants. Designers must verify pin assignments against the respective device pin-out files.

The "N" suffix on both part numbers indicates lead-free (Pb-free) packaging. The additional "S" in 5CSEBA4U19C8SN is part of the ordering code variation for that specific density and configuration. Both devices are specified as lead-free and RoHS-compliant in their respective ordering information.

No. Although both share the same 484-pin UBGA package and C8 speed grade, the 5CSEBA4U19C8SN offers 40,000 LEs versus 25,000 LEs in the 5CSEBA2U19C8N. A design that utilizes more than 25,000 LEs will not fit in the smaller device. Additionally, the HPS configuration, memory resources, and DSP block counts differ between the two densities. A drop-in replacement is only possible if the design fits within the smaller device's resources and all pin assignments are verified.

Both the 5CSEBA2U19C8N and 5CSEBA4U19C8SN integrate a dual-core ARM Cortex-A9 MPCore HPS with NEON and FPU extensions. The HPS feature set is common across Cyclone V SE SoC FPGA variants, including memory controllers, peripherals, and interfaces. However, the FPGA fabric resources available to the HPS for custom acceleration or interfacing differ due to the different LE counts.

The 5CSEBA2U19C8N (25,000 LEs) is typically used in cost-sensitive or lower-complexity embedded systems where moderate FPGA fabric is sufficient. The 5CSEBA4U19C8SN (40,000 LEs) suits applications requiring additional logic capacity, such as more complex protocol bridging, image processing, or motor control algorithms. Selection depends on resource utilization estimates from the design's synthesis and fitting reports.

Yes. Both devices are supported by Intel Quartus Prime software (Standard or Pro edition, depending on version) and the SoC FPGA Embedded Development Suite (SoC EDS). Device support is included in the same tool installations, and both use the same configuration and programming methods, including JTAG and active serial configuration.
