AFS1500-1FG256I

Overview

The AFS1500-1FG256I is a Fusion mixed-signal Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It utilizes an advanced 130-nm, 7-layer metal, flash-based CMOS process to deliver nonvolatile programmability with live-at-power-up (LAPU) capabilities. The device integrates 1,500,000 system gates and supports a maximum system performance frequency of 350 MHz. It operates within a supply voltage range of 1.42 V to 1.58 V and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 256-pin plastic ball grid array (PBGA) package with a 1 mm pitch.

Feature Summary

• Nonvolatile Flash-based architecture retains configuration data when powered off and enables immediate operation upon power-up without external boot devices.
• Integrated on-chip 1.5 V regulator allows for simplified single 3.3 V power supply designs while maintaining low internal core voltage operation.
• Supports secure in-system programming via JTAG using 128-bit AES encryption and includes FlashLock technology to protect FPGA contents from unauthorized access.

Applications

• Industrial control systems requiring high reliability and nonvolatile logic configuration
• Secure communication interfaces utilizing encrypted in-system programming
• Embedded applications needing immediate system availability at power-on

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with required environmental ratings and pinout configurations. Confirm export compliance documentation requirements prior to ordering, as this product may necessitate additional files for international shipment depending on the destination region.

Selection Notes

Select this component for designs prioritizing nonvolatile logic density and security features over ultra-high-speed serial transceivers. Ensure the design accommodates the 130-nm process characteristics and verify that the 350 MHz maximum frequency meets the timing constraints of the target application logic.

Part Context

This part belongs to the Actel Fusion family, which bridges the gap between traditional SRAM FPGAs and ASICs by offering reprogrammability with flash nonvolatility. It serves as a cost-effective solution for mid-density logic applications where power consumption and configuration security are critical design parameters.

Replacement Considerations

Direct replacements include the AFS1500-FFGG256I and M1AFS1500 variants within the same family. Verify pin-to-pin compatibility and electrical specifications before substituting, as packaging details and specific speed grades may differ between revisions.
