A3PE600-PQG208I

Overview

The A3PE600-PQG208I is a ProASIC3E Flash FPGA manufactured by Microsemi. It features 600,000 system gates and 13,824 VersaTiles within a PQFP-208 package. The device supports up to 270 user I/Os and includes 108 kbits of True Dual-Port SRAM. Operating at a maximum frequency of 350 MHz, it utilizes a 130-nm flash-based CMOS process. The industrial temperature grade (-I suffix) ensures functionality from -40°C to +100°C junction temperature.

Feature Summary

• Nonvolatile flash technology enables Instant On Level 0 support without external boot PROMs.
• Integrated security features include FlashLock protection and on-chip AES decryption for secure ISP.
• Flexible I/O structure supports mixed-voltage operation across 1.5 V, 1.8 V, 2.5 V, and 3.3 V standards.
• Six Clock Conditioning Circuits with integrated PLLs provide comprehensive clock management capabilities.

Applications

• Secure remote field updates over public networks
• Internet protocol addressing and system calibration storage
• High-density logic systems requiring instant power-up

Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm package type and temperature range. The 'PQ' indicates a Plastic Quad Flat Pack, while 'G' denotes RoHS-compliant packaging. Confirm that the 'I' suffix corresponds to the required industrial temperature specifications for your application environment.

Selection Notes

Select this component when nonvolatile configuration and high security are required. The PQ208 package limits available CCCs to two PLLs compared to larger packages. Ensure design requirements align with the 270-user I/O limit and 108 kbit SRAM capacity provided by the 600k gate density.

Part Context

This part belongs to the ProASIC3E family, representing third-generation flash FPGAs from Microsemi. It succeeds the ProASIC PLUS family, offering higher performance and density. The architecture combines reprogrammable flash with embedded ARM Cortex-M1 support options in other family members.

Replacement Considerations

Direct pin-compatible replacements within the ProASIC3E family include the A3PE1500 and A3PE3000 variants. These offer higher gate counts but maintain the same PQ208 footprint and electrical characteristics for migration purposes.

FAQ

How many PLLs are available in the PQ208 package?

While the device contains six CCC blocks, only the center east and west PLLs are accessible in the PQ208 package to maximize user I/Os.

What is the function of the on-chip FlashROM?

The 1 kbit FlashROM provides nonvolatile storage for data such as IP addresses, calibration settings, or encryption keys, accessible via JTAG or direct core addressing.

Does the device require an external configuration PROM?

No, the flash-based architecture retains programmed designs when powered off, eliminating the need for external boot PROMs and enabling Instant On functionality.
