AFS1500-FGG256

Overview

The AFS1500-FGG256 is a Fusion FPGA from Microchip Technology, utilizing advanced 130-nm Flash-based CMOS technology. It features 1.5 million system gates and 38,400 configurable logic blocks (CLBs). The device operates with a supply voltage range of 1.42 V to 1.58 V, centered at 1.5 V. It supports a maximum system frequency of 350 MHz and includes an on-chip regulator for single 3.3 V operation. Packaged in a 256-ball FBGA with 1 mm pitch, it offers industrial temperature ratings from -40°C to +85°C.

Feature Summary

• Nonvolatile Flash-based architecture enabling live at power-up functionality without external configuration memory.
• Integrated ARM Cortex-M1 processor core for embedded control applications within the FPGA fabric.
• On-chip 1.5 V voltage regulator allows direct connection to a single 3.3 V power supply.
• Supports secure in-system programming via JTAG with 128-bit AES encryption capabilities.

Applications

• Industrial automation controllers requiring nonvolatile reconfiguration.
• Automotive infotainment systems needing low power standby modes.
• Aerospace and defense avionics demanding high reliability and radiation tolerance options.
• Telecommunications infrastructure equipment requiring secure boot and firmware updates.

Procurement Notes

Verify the specific suffix requirements for your application, as package variations exist. Confirm export compliance documentation needs, as this component may require additional files for international shipping. Check current manufacturing status, as some variants are transferred or obsolete. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this model when nonvolatile configuration and embedded processing are required in a single chip. Compare gate counts against other Fusion series devices if higher logic density is needed. Verify I/O count sufficiency for interface requirements. Consider thermal management solutions given the 350 MHz operational capability and FBGA package constraints.

Part Context

This part belongs to the Microchip Fusion FPGA family, which combines Flash memory technology with programmable logic and optional embedded processors. It succeeds earlier Actel FPGA lines and integrates ARM cores for System-on-Programmable-Chip (SoPC) designs. The family emphasizes low power consumption and security features for harsh environments.

Replacement Considerations

Direct pin-compatible replacements include the U1AFS1500-FGG256I and M1AFS1500-2FG256. Verify software compatibility and timing specifications before substitution. The P1AFS1500-FG256YES is listed but requires confirmation of functional equivalence regarding the embedded processor and I/O standards.
