The M7AFS600-FG484 is a Fusion® family mixed-signal, flash-based FPGA from Microchip Technology. It pairs nonvolatile on-chip flash configuration with integrated analog resources and high-density digital fabric to address mixed-signal control, board-management, and mezzanine applications.

Built around approximately 600,000 system gates and 13,824 logic elements, this commercial-grade device provides high I/O count and embedded memory along with integrated ADCs, MOSFET gate drivers and clocking resources for compact, single-chip system designs.

Key Features

• Logic and Capacity — 13,824 logic elements (tiles) and approximately 600,000 system gates provide substantial programmable logic density for control and interface functions.
• Embedded Memory — Approximately 4 Mbits of embedded flash for configuration and user code plus approximately 0.11 Mbits (110,592 bits) of on-chip RAM for data buffering and state storage.
• Mixed-Signal Integration — Integrated A/D converters up to 12-bit resolution and up to 600 ksps, with up to 30 analog input channels and internal/external reference options; current and temperature monitoring blocks.
• MOSFET Gate Drivers — Up to 10 gate-driver outputs with P- and N‑channel MOSFET support and programmable drive strengths (including microamp and 20 mA ranges) for direct power-stage interfacing.
• On-Chip Clocking and PLLs — Internal 100 MHz RC oscillator (±1% accuracy), crystal oscillator support (32 kHz–20 MHz), six Clock Conditioning Circuits with integrated PLLs (AFS600 includes two PLLs) for flexible frequency management.
• Advanced I/O — Up to 172 digital I/Os, bank-selectable mixed-voltage operation (1.5 V, 1.8 V, 2.5 V, 3.3 V), support for single-ended and differential standards, programmable slew/drive and hot-swap capable I/Os.
• Security and In-System Programming — In-System Programming (ISP) with 128-bit AES and FlashLock® support to protect FPGA contents and enable secure updates via JTAG.
• Power and Low-Power Modes — Single 3.3 V primary supply with on-chip 1.5 V regulator; sleep and standby modes to help manage system power.
• Package and Temperature — 484-ball FPBGA (23 × 23) surface-mount package; commercial operating temperature range 0 °C to 70 °C.
• Compliance — RoHS compliant.

Typical Applications

• ATCA and Board Management — Targeted Pigeon Point ATCA IP support and Board Management Reference (BMR) starter kit compatibility for system management implementations.
• Advanced Mezzanine and Module Designs — MicroBlade Advanced Mezzanine Card support (AdvancedMC™ designs) for mezzanine modules and carrier boards.
• Mixed-Signal Sensor Acquisition — On-chip ADCs and analog I/O enable direct sensor signal acquisition and front-end integration without extensive external components.
• Power-Stage and MOSFET Control — Integrated gate drivers and high-voltage-tolerant analog inputs allow direct interfacing to MOSFETs and power-management circuits.

Unique Advantages

• Nonvolatile, Instant-On Capability: Flash-based configuration retains program state when powered off and enables immediate startup without external configuration memories.
• Highly Integrated Mixed-Signal Peripherals: ADCs, analog inputs, and MOSFET gate drivers reduce external BOM and simplify mixed-signal system designs.
• Flexible I/O Voltage Support: Bank-selectable I/O voltages and broad I/O standard support simplify board-level interfacing across multiple voltage domains.
• Secure In-System Updates: 128-bit AES ISP and FlashLock® support help protect intellectual property and enable secure field updates.
• Scalable Fusion Family Compatibility: Pin-compatible packages across the Fusion family provide migration and scaling options within the same package footprint.
• Compact, High-I/O Package: 484-FPBGA (23×23) delivers up to 172 digital I/Os in a surface-mount BGA suitable for space-constrained boards.
