A54SX32-PQG208M

The A54SX32-PQG208M is a nonvolatile SX-A family FPGA from Microchip Technology, delivering 48,000 system gates in a single-chip programmable device. Its architecture provides deterministic timing and in-system diagnostic capability, making it suitable for designs that require reliable, reprogrammable logic with robust I/O options.

With 2,880 logic elements and 174 user I/Os in a 208-pin package, the device targets applications that need moderate logic density, flexible mixed-voltage I/O, and operation across a wide temperature range—backed by military-grade qualification and RoHS compliance.

Key Features

• Core Capacity — 48,000 system gates and 2,880 logic elements provide substantial programmable logic for mid-density designs.
• User I/O — 174 user-configurable I/O pins on the 208-pin package enable broad interfacing options for peripherals and buses.
• No On-Chip RAM — Total RAM bits: 0; design emphasis is on logic and flip-flop based resources.
• Performance — Datasheet family specifications list up to 250 MHz system performance and 350 MHz internal performance for timing-critical paths.
• Flexible Voltage Support — Operates from 3 V to 5.5 V and supports mixed-voltage I/O modes as specified for the SX-A family, simplifying integration with varied logic levels.
• Rugged Temperature & Grade — Military-grade device with operating temperature from −55 °C to 125 °C for demanding environments.
• Package — 208-pin BFQFP / PQFP form-factor (supplier device package listed as 208-PQFP, 28×28) for compact board-level integration.
• In-System Diagnostics & Security — Family features include in-system diagnostic and verification with Silicon Explorer II and Actel Secure Programming Technology with FuseLock for design protection.
• System Reliability — Hot-swap compliant I/Os, power-up/power-down friendly operation (no supply sequencing required), boundary-scan (IEEE 1149.1) for testability, and individual output slew rate control.
• Standards Support — SX-A family devices include 66 MHz PCI compliance and configurable I/O options for common logic families as documented in the datasheet.
• Regulatory — RoHS compliant.

Typical Applications

• Defense & Aerospace — Military-grade temperature range (−55 °C to 125 °C) and rugged qualification suit avionics, avionics support electronics, and other defense systems requiring reliable programmable logic.
• Industrial Control — Wide supply range (3 V to 5.5 V), hot-swap–friendly I/Os, and deterministic timing make the device appropriate for motor control, automation controllers, and factory instrumentation.
• PCI-Based Systems — 66 MHz PCI compliance and abundant I/O enable bridging, custom bus logic, and peripheral interface implementations in board-level systems.
• Embedded Logic & Prototyping — 2,880 logic elements and 48,000 system gates provide a flexible platform for embedded control, glue logic, and iterative hardware development where in-system reprogramming and diagnostics are needed.

Unique Advantages

• Highly Integrated Logic Density: 48,000 system gates and 2,880 logic elements reduce external glue logic and simplify system design.
• Wide I/O Flexibility: 174 user I/Os and mixed-voltage operation allow direct interfacing to multiple bus standards and legacy peripherals.
• Military-Grade Reliability: Qualified for −55 °C to 125 °C operation, suitable for harsh environmental deployments.
• Nonvolatile Single-Chip Solution: SX-A family single-chip nonvolatile architecture eliminates the need for external configuration memory.
• Built-in Test & Security: Boundary-scan (IEEE 1149.1), Silicon Explorer II diagnostics, and FuseLock secure programming support manufacturing testability and IP protection.
• Powering & Board Integration: 3 V–5.5 V supply range with power-up/power-down friendliness reduces power-sequencing constraints during system integration.
