AGL125V5-FG144

Overview

The AGL125V5-FG144 is a flash-based Field Programmable Gate Array (FPGA) from the IGLOO family, manufactured by Microchip Technology. It features 125,000 system gates and 3,072 VersaTiles within a 144-pin Fine Pitch Ball Grid Array (FG144) package. The device operates with a core voltage range of 1.2 V to 1.5 V and supports up to 97 user I/Os. It includes 36 kbits of embedded SRAM and 1 kbit of FlashROM. The component provides Instant On capability, AES-protected in-system programming, and Flash*Freeze technology for ultra-low power consumption.

Feature Summary

• Flash*Freeze technology enables rapid entry into an ultra-low power mode while retaining FPGA content and register data without external components.
• Instant On Level 0 support allows immediate operation upon power-up, eliminating the need for external configuration PROMs or boot devices.
• Integrated AES decryption engine secures intellectual property and enables secure remote in-system programming via JTAG.
• Nonvolatile flash architecture ensures firm-error immunity against high-energy neutrons and retains programmed designs when powered off.

Applications

• Portable electronics requiring low static power and instant-on functionality
• Secure field upgrades and remote in-system programming applications
• System initialization and critical task execution before main processor wake-up

Procurement Notes

Verify the specific ordering suffix 'V5' indicates the 1.5 V only supply voltage variant as per the datasheet nomenclature. Confirm the FG144 package dimensions and pinout match the target PCB footprint. Ensure the design accounts for the commercial temperature grade unless an industrial suffix is specified. Cross-reference the part number with the latest Microchip documentation to confirm current production status and availability.

Selection Notes

Select this device for designs requiring nonvolatile reprogrammability with minimal logic density. The 125,000 gate count suits moderate complexity logic functions. Consider the 1.2 V to 1.5 V core voltage flexibility for power optimization. Verify that the 97 available user I/Os meet interface requirements. Evaluate the integrated PLL and CCC blocks if clock conditioning is necessary without external components.

Part Context

This component belongs to the IGLOO Low Power Flash FPGA family, which utilizes a 130-nm flash process. It shares architectural similarities with other IGLOO devices like the AGL060 and AGL250 but offers a specific balance of logic resources and I/O count. The FG144 package is common across several densities in the family, facilitating pin-compatible design migrations.

Replacement Considerations

For direct pin-compatible replacements within the same package, consider the AGL125V2-FG144 or AGL1252-FGG144I. These parts share the 144-ball FBGA footprint and similar I/O counts. Verify voltage specifications and feature sets, such as AES security and Flash*Freeze support, to ensure functional equivalence.
