XC7A35T-1CSG324C Artix-7 FPGA for Compact Designs

ElecSuppliers Part Number GuideSep 06, 2026

The XC7A35T-1CSG324C is an AMD Xilinx Artix-7 FPGA designed for digital systems that need programmable logic, high-speed interfaces and substantial processing resources without moving to a larger FPGA family. With 33,280 logic cells, 90 DSP slices, integrated memory and four GTP transceivers, it provides a practical balance between processing capability, connectivity and board space.

The device uses the -1 speed grade and a 324-CSPBGA package, making it suitable for commercial-temperature applications where a compact FPGA footprint and flexible hardware architecture are important.

XC7A35T-1CSG324C Logic and Processing Resources

The XC7A35T family is based on Xilinx 7-series FPGA architecture and uses 6-input LUT technology for implementing configurable digital logic. The XC7A35T-1CSG324C provides 33,280 logic cells and 2,600 CLB/LAB resources for implementing control logic, data paths, state machines and parallel processing functions.

The FPGA also includes 90 DSP slices. These resources are useful for multiplication, accumulation and filtering operations, allowing signal-processing workloads to be implemented directly in programmable logic rather than relying entirely on an external processor.

For designs that require both control and computation, the available logic and DSP resources provide room for implementing custom hardware accelerators, interface controllers and real-time processing pipelines.

Memory for On-Chip Data Processing

Memory resources are another important part of the XC7A35T-1CSG324C architecture. The device provides approximately 1.84 Mbit of total RAM, including dedicated block RAM and distributed RAM.

The block RAM resources can be configured for functions such as FIFO buffers, lookup tables, packet storage and intermediate data processing. Distributed RAM can also be used within the programmable logic for smaller and frequently accessed data structures.

This combination allows many embedded designs to keep critical data close to the processing logic and reduce dependence on external memory.

Four GTP Transceivers for High-Speed Connectivity

The XC7A35T-1CSG324C integrates four GTP transceivers, giving the FPGA high-speed serial connectivity for suitable chip-to-chip and system-level interfaces.

The transceiver resources can be useful in applications involving high-speed data acquisition, communications, instrumentation and other systems where conventional parallel interfaces would require more PCB traces and additional hardware.

The device also includes PCI Express capability and high-performance SelectIO resources, expanding its usefulness in systems that need programmable interface logic alongside high-speed data transfer.

324-CSPBGA Package

The XC7A35T-1CSG324C uses a 324-CSPBGA package with an approximately 15 mm × 15 mm body size. The package provides 210 user I/O connections while keeping the FPGA footprint relatively compact.

Package selection is important when designing an FPGA-based board because the number of available I/O pins affects memory interfaces, peripheral connections, clock routing and high-speed signal placement.

Compared with larger Artix-7 packages, the 324-CSPBGA option can be attractive for designs where PCB area and routing density need to be controlled.

Commercial Temperature and Speed Grade

The XC7A35T-1CSG324C is a commercial-temperature device specified for 0°C to +85°C junction operation. The -1 speed grade identifies its performance class within the XC7A35T family.

This combination makes the part a practical option for commercial electronics, laboratory equipment, communications hardware, embedded computing and other systems operating within a controlled temperature environment.

Designers should compare speed grade, package and temperature rating carefully when replacing an XC7A35T device because otherwise similar-looking part numbers can have different electrical and environmental characteristics.

Applications of XC7A35T-1CSG324C

The XC7A35T-1CSG324C can be used in a wide range of programmable digital systems. Its combination of FPGA logic, DSP resources, internal memory and serial connectivity supports applications such as industrial measurement equipment, video and image processing, data acquisition systems, communications equipment, test instruments and embedded control platforms.

Its programmable architecture is particularly useful when product requirements may change during development. Hardware interfaces and processing functions can be modified through FPGA logic without redesigning the entire system around a fixed-function device.

XC7A35T-1CSG324C in Embedded Hardware Design

For engineers selecting an FPGA for a new board, the XC7A35T-1CSG324C offers a useful middle ground between small low-cost programmable devices and larger FPGAs with substantially higher logic capacity.

The 33,280 logic cells provide enough capacity for sophisticated interface and control designs, while the 90 DSP slices and approximately 1.84 Mbit of RAM support more demanding signal-processing workloads. Four GTP transceivers further extend its capabilities for high-speed system connectivity.

The 324-CSPBGA package also gives designers a relatively compact implementation while retaining 210 I/O connections. For commercial systems requiring programmable logic, high-speed interfaces and moderate processing capacity, XC7A35T-1CSG324C remains a relevant Artix-7 device to consider.
