ProASIC3 Flash Family FPGAs Datasheet with Optional Soft ARM Support

Category: Electronics, Microsemi Corp, Programmable Logic ICS

Executive Summary

The datasheet presents detailed information about the ProASIC3 Flash Family FPGAs (Field-Programmable Gate Arrays), produced by Microsemi Corporation, which can optionally support soft ARM Cortex-M1 processors. This family of FPGAs is designed for a broad spectrum of electronic applications, boasting features aligned with high-performance and flexible system design requirements.

The FPGAs include models ranging from 15K to 1M system gates, offering scalability for different project sizes and complexities. Each FPGA in the series is equipped with up to 144 Kbits of true dual-port SRAM and up to 300 user I/Os with bank-selectable voltages, enhancing the customization for various operational voltages and interfacing needs.

Key Performance and Configuration Features

High-Speed I/O Capabilities: The devices are capable of up to 700 Mbps DDR and support LVDS with advanced I/Os for the A3P250 model and above.
Multiple I/O Standards: They support a wide range of single-ended I/O standards including LVTTL, LVCMOS, and PCI, along with differential standards such as LVPECL, LVDS, and M-LVDS.
Reprogrammable Flash Technology: Offers the flexibility of reprogramming, with instant-on capabilities and a retention of the programmed design when powered off.
High System Performance: FPGAs are capable of 350 MHz system performance, with features such as high programmable output slew rate and drive strength, as well as in-system programming (ISP) and security provided by on-chip 128-bit AES decryption.
Low Power Consumption: Optimized for low power operation which is crucial for power-sensitive applications.
Embedded Memory and ARM Processor Support: Includes support for various memory configurations and optional ARM Cortex-M1 soft processors in ProASIC3 devices, expanding their suitability for system-on-chip (SoC) designs.
Packaging: The FPGAs are available in multiple package types including QFN, VQFP, TQFP, PQFP, and FBGA with different pin counts to cater to various space requirements.

Design Considerations

Designers should note that certain models, such as the A3PO15, are not recommended for new designs. Additionally, AES encryption is not available on Cortex-M1 equipped ProASIC3 devices. For a greater number of gates and additional features, the ProASIC3E Flash FPGA family is recommended.

Applications and Advantages

This FPGA series is well-suited for applications requiring high reliability, instantaneous operation upon power-up, and secure in-system programmability. With an array of package options and extensive memory features, the ProASIC3 FPGAs are highly versatile for a variety of industrial, commercial, and defense-related applications.
