M1AFS250-PQG208

Field Programmable Gate Array Overview

The M1AFS250-PQG208 is a Fusion mixed-signal FPGA from Microsemi Corporation, featuring 250,000 system gates and 6,144 tiles. It utilizes an advanced 130-nm, 7-layer metal flash-based CMOS process for nonvolatile configuration. The device integrates an ARM Cortex-M1 processor, embedded flash memory blocks totaling 2 Mbits, and a 12-bit ADC with up to 600 Ksps sampling rate. It operates on a single 3.3 V supply with an internal 1.5 V regulator. The PQG208 package provides 93 digital I/Os and 26 analog I/Os in a 208-pin Plastic Quad Flat Pack (PQFP) format.

Field Programmable Gate Array Feature Summary

• Integrates an ARM Cortex-M1 soft processor within the FPGA fabric for system management and control applications.
• Features Instant On capability due to nonvolatile flash technology, eliminating the need for external boot PROMs.
• Includes integrated analog peripherals such as a 12-bit ADC, MOSFET gate drivers, and current/temperature monitors.
• Provides high security through FlashLock and 128-bit AES encryption for IP protection and secure in-system programming.

Field Programmable Gate Array Applications

• Power management and smart battery charging systems
• Clock generation and management circuits
• Motor control applications

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix associated with the PQG208 package, as standard Fusion devices offer multiple performance tiers. Confirm that the industrial temperature range variant is required if operating conditions exceed commercial limits. Ensure the design flow supports the Libero SoC software suite for configuring the mixed-signal peripherals and ARM core integration effectively.

Field Programmable Gate Array Selection Notes

Select this component when a single-chip solution combining programmable logic, analog signal processing, and embedded processing is required. The M1AFS250 offers sufficient gate density for moderate complexity designs while providing extensive analog I/O capabilities. Consider the pin-compatible AFS250 or U1AFS250 variants if ARM integration or specific board management features are not needed.
