AFS1500-FG256

Overview

The AFS1500-FG256 is a Fusion FPGA from Microchip Technology, featuring 1.5 million system gates and 38,400 configurable logic blocks (CLBs). It operates within a supply voltage range of 1.42 V to 1.58 V, with a nominal rating of 1.5 V. The device supports an industrial temperature range from -40°C to +85°C and utilizes a 256-pin FBGA package with a 1 mm pitch. It incorporates nonvolatile flash technology for instant-on functionality and includes embedded user flash memory.

Feature Summary

• Instant-on capability via Live at Power-Up (LAPU) technology
• Nonvolatile flash-based architecture retaining configuration when powered off
• Integrated on-chip 1.5 V regulator allowing single 3.3 V supply operation
• Supports in-system programming and secure JTAG access

Applications

• Industrial control systems requiring instant power-up
• Embedded applications needing nonvolatile reprogrammable logic
• Low-power mixed-signal designs utilizing integrated regulators

Procurement Notes

Verify export compliance requirements as this product may require additional documentation for shipment from the United States. Confirm moisture sensitivity level (MSL 3) handling procedures during storage and assembly. Ensure RoHS status aligns with project specifications, noting potential variations in lead-free certification across manufacturing batches.

Selection Notes

Select this component for designs prioritizing instant-on performance and nonvolatile configuration retention. Compare against SRAM-based FPGAs if power consumption during standby is critical. Verify that the 256-pin FBGA footprint matches the PCB layout constraints and that the 1.5 V core voltage is compatible with the system power budget.

Part Context

This part belongs to the Actel Fusion family, which combines high-performance flash FPGA fabric with optional ARM Cortex-M1 processor support. The AFS1500 variant represents the 1.5 million gate density tier within the series, offering a balance of logic capacity and low power consumption suitable for mid-range embedded applications.

Replacement Considerations

Direct substitutes include other packages within the same density tier, such as AFS1500-FFGG256I or AFS1500-FGG484K, depending on pin count requirements. Cross-family migration to PolarFire or IGLOO devices requires significant design adaptation due to architectural differences.
