AFS600-PQ208I

Overview

The Microsemi AFS600-PQ208I is a Field Programmable Gate Array featuring 600,000 system gates and 13,824 tiles. It utilizes an advanced 130-nm, 7-layer metal flash-based CMOS process for nonvolatile configuration. The device supports a maximum system performance of 350 MHz with input frequencies ranging from 1.5 to 350 MHz and output frequencies from 0.75 to 350 MHz. It includes 4 Mbits of embedded user flash memory and 1 Kbit of FlashROM. The integrated analog subsystem comprises up to 10 analog quads, supporting 30 scalable ADC input channels with up to 12-bit resolution at 600 Ksps. The PQ208 package provides 95 digital I/Os and 46 analog I/Os.

Feature Summary

• Instant On capability due to nonvolatile flash technology that retains program data when powered off without external boot PROMs.
• Integrated mixed-signal architecture combining high-performance FPGA fabric with analog peripherals including a configurable ADC and MOSFET gate drivers.
• Advanced security features utilizing 128-bit AES encryption via JTAG and FlashLock to protect intellectual property and configuration data.
• Low power consumption supported by a single 3.3 V supply with an on-chip 1.5 V regulator and dedicated sleep and standby modes.

Applications

• Power management systems requiring voltage monitoring and control
• Smart battery charging applications with integrated current sensing
• Clock generation and management using internal oscillators and PLLs
• Motor control implementations leveraging analog inputs and gate drivers

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'PQ' designation indicates a Plastic Quad Flat Pack, while 'I' specifies the industrial temperature range. Ensure compatibility with Libero SoC software tools for design implementation and programming. Confirm RoHS compliance status if required for your manufacturing standards.

Selection Notes

Select this model for designs requiring high-density logic alongside significant analog processing capabilities within a single chip. The PQ208 package offers a balance of I/O count and physical footprint suitable for space-constrained boards. Consider the 350 MHz speed grade if high-frequency digital processing is necessary alongside real-time analog signal acquisition.

Part Context

This component belongs to the Fusion family of mixed-signal FPGAs manufactured by Microsemi Corporation. The Fusion series integrates flash-based programmable logic with analog peripherals, distinguishing it from standard SRAM-based FPGAs. It shares architectural similarities with other Fusion devices like the AFS250 and AFS1500 but offers higher logic density and more analog resources.

Replacement Considerations

Pin-compatible alternatives within the same package include the AFS250-PQ208I, though it offers lower logic density. For higher capacity needs, migration to the FG484 package variants such as the AFS600-1FG484I may be considered, but requires PCB redesign due to different pinout and form factor.
