M2GL090T-FG484 - 86K Cell 1.2V Flash FPGA | Microchip
The Microchip Technology M2GL090T-FG484 is an IGLOO2 flash FPGA with 86,316 logic cells, 267 I/O, and a nominal 1.2 V core supply in a 484-pin FBGA package. It combines reprogrammable nonvolatile configuration storage with an embedded programmable-logic fabric for general-purpose control, interface, bridging, conversion, video and image processing, and secure connectivity functions. The M2GL090 device combines 86,316 logic cells with 267 available I/O to support integration of multiple fixed-function blocks into a single FPGA implementation. Its 484-pin FBGA package provides a high pin count for parallel interfaces and external memory connections. The 1.2 V supply is the nominal core operating voltage identified in the manufacturer product data; detailed voltage limits, timing grades, and current budgets must be confirmed in the device documentation. Unlike mask-programmable logic or SRAM-only FPGAs, the IGLOO2 family stores its configuration in flash, allowing the device to retain its programmed logic after power is removed.
An FPGA is a user-programmable semiconductor whose digital logic blocks, routing resources, and I/O cells are configured to implement custom hardware functions. Within the broader semiconductor hierarchy, an FPGA is a programmable-logic device, while the IGLOO2 belongs to the low-density flash-FPGA segment of the Microchip product portfolio. It is intended for designs where parallel logic, protocol conversion, control-plane processing, or system-management functions benefit from hardware-level configurability and shorter development cycles than application-specific ASIC development.
Key features include 86,316 logic cells, 267 I/O, embedded flash configuration, and a 1.2 V nominal core supply. The large I/O count makes the device suitable for parallel control interfaces, bus bridging, I/O expansion, and protocol conversion. Its nonvolatile configuration supports field updates without requiring a separate configuration SRAM, while the high-pin-count FBGA package can reduce external glue logic when many signals must leave the device. Microchip identifies the IGLOO2 family for Gigabit Ethernet or dual PCI Express control planes, bridging, I/O expansion and conversion, video and image processing, system management, and secure connectivity.
The device architecture is organized around programmable logic elements, programmable interconnect, user I/O, dedicated configuration resources, and embedded flash memory. Configuration is retained in flash, so startup behavior does not depend on an external configuration loader for normal operation. Design migration within the M2GL025, M2GL050, and M2GL090 devices using the FG484 package is addressed by Microchip application note AC402, although each migration still requires checking speed grade, temperature grade, voltage, resource utilization, pin constraints, and board-level compatibility. The target suffix “T” denotes the ordering configuration shown in the verified results, while the exact commercial and temperature classifications should be checked against the ordering information.
Typical applications include Gigabit Ethernet control-plane logic, dual PCI Express control-plane functions, data and protocol bridging, parallel-to-serial or serial-to-parallel conversion, industrial I/O expansion, video and image-processing pipelines, secure-connectivity hardware, and general system-management controllers. The 267-I/O device is particularly useful where many independent digital channels must terminate on one programmable component, while the embedded flash configuration allows field-programmable behavior to be updated without volatile reload through an external programmer.
A key design consideration is package and migration validation. Before reusing an existing FG484 layout, engineers should review the IGLOO2 Packaging and Pin Descriptions User Guide and application note AC402, verify power rails and I/O standards, and confirm that the selected device provides every required bank and peripheral connection. Differential, high-speed, clock, configuration, and supply pins must also satisfy the manufacturer’s routing and decoupling guidance.
This product record consolidates verified manufacturer and distributor information, identifies same-package family alternatives, compares ordering variants, and adds practical migration and design guidance. It separates confirmed facts from unavailable pricing, lifecycle, compliance, and detailed timing information so engineers can review the appropriate manufacturer documents before committing a design to production.
