1 – ProASIC3 Device Family Overview
General Description
ProASIC3, the third-generation family of Actel flash FPGAs, offers performance, density, and features
beyond those of the ProASIC
advantage of being a secure, low power, single-chip solution that is live at power-up (LAPU). ProASIC3
is reprogrammable and offers time-to-market benefits at an ASIC-level unit cost. These features enable
designers to create high-density systems using existing ASIC or FPGA design flows and tools.
ProASIC3 devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as
clock conditioning circuitry based on an integrated phase-locked loop (PLL). The A3P015 and A3P030
devices have no PLL or RAM support. ProASIC3 devices have up to 1 million system gates, supported
with up to 144 kbits of true dual-port SRAM and up to 300 user I/Os.
ProASIC3 devices support the ARM Cortex-M1 processor. The ARM-enabled devices have Actel
ordering numbers that begin with M1A3P (Cortex-M1) and do not support AES decryption.
Flash Advantages
Reduced Cost of Ownership
Advantages to the designer extend beyond low unit cost, performance, and ease of use. Unlike SRAM-
based FPGAs, flash-based ProASIC3 devices allow all functionality to be live at power-up; no external
boot PROM is required. On-board security mechanisms prevent access to all the programming
information and enable secure remote updates of the FPGA logic. Designers can perform secure remote
in-system reprogramming to support future design iterations and field upgrades with confidence that
valuable intellectual property (IP) cannot be compromised or copied. Secure ISP can be performed using
the industry-standard AES algorithm. The ProASIC3 family device architecture mitigates the need for
ASIC migration at higher user volumes. This makes the ProASIC3 family a cost-effective ASIC
replacement solution, especially for applications in the consumer, networking/ communications,
computing, and avionics markets.
Security
The nonvolatile, flash-based ProASIC3 devices do not require a boot PROM, so there is no vulnerable
external bitstream that can be easily copied. ProASIC3 devices incorporate FlashLock, which provides a
unique combination of reprogrammability and design security without external overhead, advantages that
only an FPGA with nonvolatile flash programming can offer.
ProASIC3 devices utilize a 128-bit flash-based lock and a separate AES key to secure programmed
intellectual property and configuration data. In addition, all FlashROM data in ProASIC3 devices can be
encrypted prior to loading, using the industry-leading AES-128 (FIPS192) bit block cipher encryption
standard. The AES standard was adopted by the National Institute of Standards and Technology (NIST)
in 2000 and replaces the 1977 DES standard. ProASIC3 devices have a built-in AES decryption engine
and a flash-based AES key that make them the most comprehensive programmable logic device security
solution available today. ProASIC3 devices with AES-based security allow for secure, remote field
updates over public networks such as the Internet, and ensure that valuable IP remains out of the hands
of system overbuilders, system cloners, and IP thieves. The contents of a programmed ProASIC3 device
cannot be read back, although secure design verification is possible.
ARM-enabled ProASIC3 devices do not support user-controlled AES security mechanisms. Since the
ARM core must be protected at all times, AES encryption is always on for the core logic, so bitstreams
are always encrypted. There is no user access to encryption for the FlashROM programming data.
Security, built into the FPGA fabric, is an inherent component of the ProASIC3 family. The flash cells are
located beneath seven metal layers, and many device design and layout techniques have been used to
make invasive attacks extremely difficult. The ProASIC3 family, with FlashLock and AES security, is
unique in being highly resistant to both invasive and noninvasive attacks. Your valuable IP is protected
