1 – Automotive ProASIC3 Device Family Overview

General Description

Automotive ProASIC3 nonvolatile flash technology gives automotive system designers the

advantage of a secure, low-power, single-chip solution that is live at power-up (LAPU). Automotive

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.

Automotive 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).

Automotive ProASIC3 devices have up to 1 million system gates, supported with up to 144 kbits of

SRAM and up to 300 user I/Os.

Automotive ProASIC3 devices are the only firm-error-immune automotive grade FPGAs. Firm-error

immunity makes them ideally suited for demanding applications in powertrain, safety, and

telematics-based subsystems, where firm-error failure is not an option.

Firm errors in SRAM-based FPGAs can result in high defect levels in field-deployed systems. These

unavoidable defects must be considered separately from standard defects and failure mechanisms

when looking at overall system quality and reliability.

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 Automotive 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. Flash-based

FPGAs are LAPU Class 0 devices, offering the lowest available power in a single-chip device and

providing firm-error immunity. The Automotive ProASIC3 family device architecture mitigates the

need for ASIC migration at high user volumes. This makes the Automotive ProASIC3 family a cost-

effective ASIC replacement solution, especially for automotive applications.

Security

The nonvolatile, flash-based Automotive ProASIC3 devices do not require a boot PROM, so there is

no vulnerable external bitstream that can be easily copied. Automotive 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.

Automotive 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

Automotive ProASIC3 devices can be encrypted prior to loading, using the industry-leading AES-

128 (FIPS192) bit block cipher encryption standard. The AES was adopted by the National Institute

of Standards and Technology (NIST) in 2000 and replaces the 1977 DES standard. Automotive

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. Automotive

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 Automotive ProASIC3

device cannot be read back, although secure design verification is possible. Additionally, security

features of Automotive ProASIC3 devices provide anti-tampering protection.

Security, built into the FPGA fabric, is an inherent component of the Automotive ProASIC3 family.

The flash cells are located beneath seven metal layers, and many device design and layout
