AFS090-FGG256I

Overview

The AFS090-FGG256I is a mixed-signal Field Programmable Gate Array (FPGA) from the Microsemi Fusion family, manufactured using an advanced 130-nm flash-based CMOS process. It integrates nonvolatile FPGA fabric with embedded analog peripherals and memory on a single chip. The device features 90,000 system gates and 2,304 tiles (D-flip-flops). It includes one 2 Mbit Flash Memory Block, 1 Kbit of FlashROM, and 27 kbits of SRAM organized into six 4,608-bit blocks. Key analog resources consist of five Analog Quads providing 15 input channels, up to 600 Ksps ADC performance with 12-bit resolution, and five MOSFET gate driver outputs. The package is a 256-pin Fine Pitch Ball Grid Array (FG256) supporting industrial temperature range (-40°C to +100°C).

Feature Summary

• Instant On operation enabled by nonvolatile flash technology, eliminating the need for external configuration boot PROMs.
• Integrated mixed-signal capabilities including a 12-bit ADC, high-voltage tolerant analog inputs, and programmable MOSFET gate drivers.
• Advanced security features utilizing FlashLock and 128-bit AES encryption to protect intellectual property and enable secure in-system programming.
• Comprehensive clocking support with internal oscillators and programmable clock conditioning circuits.

Applications

• Power management systems and smart battery charging controllers.
• Motor control applications requiring integrated analog sensing and logic.
• Clock generation and management solutions replacing discrete components.
• System supervisor and management functions monitoring voltage supplies.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +100°C) as defined in the datasheet. Confirm the FG256 package designation matches the required pin count and footprint. Ensure the part number corresponds to the standard speed grade unless faster performance is explicitly required. Cross-reference the manufacturer's current product status to confirm availability.

Selection Notes

Select this device when a compact solution combining digital logic, nonvolatile storage, and analog signal processing is required. The AFS090 offers sufficient logic density for moderate complexity designs while reducing bill-of-materials costs by integrating analog peripherals. Consider the FG256 package constraints regarding I/O availability and thermal dissipation for the target application environment.

Part Context

The AFS090 represents the entry-level density within the Fusion mixed-signal FPGA family. It shares architectural similarities with higher-density variants like the AFS250 and AFS600 but provides fewer analog quads and logic tiles. This positioning makes it suitable for cost-sensitive applications that still require the benefits of flash-based reprogrammability and integrated analog functionality.

Replacement Considerations

Devices such as the AFS090-1FG256I offer a faster speed grade within the same package and feature set. Higher-density alternatives like the AFS250-FGG256I provide increased logic capacity and additional analog resources while maintaining pin compatibility.
