AGL400V5-FGG256I

Overview

The AGL400V5-FGG256I is a Microchip IGLOO low-power flash FPGA featuring 400,000 system gates and 9,216 VersaTiles. It operates on a 130-nm process with core voltage support of 1.5 V only (suffix V5). The device includes 54 kbits of true dual-port SRAM, one integrated PLL within six Clock Conditioning Circuits, and 1 kbit of FlashROM. It provides up to 177 single-ended user I/Os in the FG256 package. Key features include Flash*Freeze technology for ultra-low power retention, AES-protected ISP, and Instant On capability.

Feature Summary

• Flash*Freeze technology enables rapid entry into an ultra-low power mode that retains SRAM and register data while consuming minimal energy.
• Nonvolatile flash architecture eliminates the need for external configuration boot PROMs, providing instant-on functionality and firm-error immunity.
• Integrated security mechanisms include FlashLock protection and AES-128 decryption for secure in-system programming.
• Advanced I/O structure supports mixed-voltage operation across multiple banks with programmable slew rates and drive strengths.

Applications

• Portable electronics requiring extended battery life through low static and dynamic power consumption
• Secure remote field updates utilizing AES-protected in-system programming capabilities
• System initialization tasks and critical logic execution prior to processor wake-up

Procurement Notes

Verify the ordering suffix 'V5' confirms 1.5 V core voltage operation only, distinct from V2 variants supporting 1.2 V to 1.5 V ranges. Confirm the 'I' suffix indicates industrial temperature range availability if required by the application environment. Ensure the FG256 package footprint matches the PCB layout specifications for the Fine Pitch Ball Grid Array form factor.

Selection Notes

Select this model for designs requiring 400,000 system gates with nonvolatile reprogrammability. The V5 suffix restricts core voltage to 1.5 V; choose V2 if 1.2 V operation is necessary for lower power. Verify that the 177 available user I/Os in the FG256 package meet interface requirements. Consider the integrated PLL for clock conditioning needs without external components.

Part Context

This component belongs to the IGLOO family of low-power flash FPGAs manufactured by Microchip Technology. The AGL400 variant offers 400,000 system gates, positioning it between the AGL250 and AGL600 densities. The FG256 package provides a compact solution with high pin count relative to its footprint size.

Replacement Considerations

AGL400V2-FGG256I: Supports 1.2 V to 1.5 V core voltage instead of 1.5 V only. Pin-compatible within the same density tier.
