SX-A

Overview

Microsemi SX-A devices can match the speed and performance of an ASIC. SX-A devices can be used to generate system-wide savings by integrating multiple functions into a low cost, single-chip solution. Providing a combination of performance, security, and low power, SX-A decreases the premium for performance while providing a solution highly secure from reverse engineering.

12,000 to 108,000 usable system gates
350 MHz internal clock frequency
66 MHz, 64-bit 3.3 V / 5.0 V PCI performance (supporting Target, Master and Master/Target)
2.5 V, 3.3 V, and 5.0 V mixed-voltage support
100% resource utilization with 100% pin locking
Available in military and automotive temperature grades

SX devices have been classified as a "legacy" device. For more information, visit the Legacy & Discontinued Antifuse FPGAs page.

Design Resources

Design Software	The SX-A family of FPGAs are fully supported by Microsemi Libero Integrated Design Environment (IDE), a design management environment that guides the user through the FPGA design flow and provides seamless design tool integration, as well as project, data file, and log file management. Libero IDE enables users to integrate both schematic and HDL synthesis into a single flow and verify the entire design in a single environment.
Programming & Debug	Axcelerator FPGAs are supported by Silicon Sculptor 3, a single-site programmer driven via a PC-based GUI, provides programming support. Silicon Explorer II is an integrated hardware and software solution that, in conjunction with the Designer tools, enables designers to examine any of the internal nodes of a device operating in a prototype or a production system.
IP Cores	Search for SX-A IP cores
Partners	Many of Microsemi’s Partners are engaged in development with SmartFusion devices
Power Analysis	Leverage our Excel based SX-A Power Calculator to evaluate power for your design without running through the full design flow. SmartPower can also provide design specific power analysis for your design implementation within Libero.
IBIS Models	Generic SX-A IBIS Models are available for signal integrity simulations. Design specific files can also be exported from your design implementation in Libero.
BSDL Models	Generic SX-A BSDL Models are available for boundary scan testing. Design specific files can also be exported from your design implementation in Libero.
