A54SX32A-TQG100M

The A54SX32A-TQG100M is a nonvolatile SX-A family FPGA from Microchip Technology, packaged in a 100-pin thin quad flat pack (TQFP) surface-mount package. It provides 48,000 system gates implemented as approximately 2,880 logic elements with 81 user I/Os, targeting applications that require reprogrammable digital logic with robust I/O configurability and extended temperature capability.

This device combines in-system programmability and built-in security features with wide supply-voltage support and a military temperature grade, making it suitable for designs that demand deterministic timing, configurable I/O behavior, and long-term reliability in harsh environments.

Key Features

• Logic Capacity — Approximately 48,000 system gates implemented as 2,880 logic elements (combinatorial cells and register resources) to implement custom digital functions.
• User I/O — 81 user-programmable I/O pins with configurable I/O support for multiple voltage standards and selectable pull-up/pull-down behavior at power-up.
• Nonvolatile Single-Chip Solution — Device retains configuration without external configuration memory, simplifying board design and power sequencing.
• Performance — Datasheet-series performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical logic.
• Mixed-Voltage and 5 V Tolerance — Supports mixed 2.5 V, 3.3 V, and 5 V operation with 5 V input tolerance and 5 V drive strength where applicable, and a stated supply range of 2.25 V to 5.25 V.
• Power-Up/Down Friendly — No sequencing required for supply voltages, easing power-supply design and board integration.
• System and Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability (Silicon Explorer II referenced in series datasheet).
• Security — Incorporates Actel Secure Programming technology (FuseLock™) to protect designs from reverse engineering as described in the series documentation.
• Package and Grade — 100-LQFP (TQFP 14×14) surface-mount package, supplied in a military grade offering with operating temperature range of −55 °C to +125 °C.
• RoHS Compliant — Device is RoHS compliant per supplier data.

Typical Applications

• Military and Rugged Systems — Military-grade temperature range and robust packaging make the device suitable for applications requiring reliable operation from −55 °C to +125 °C.
• PCI and Legacy Interface Designs — Configurable I/O support for 3.3 V and 5 V PCI and 5 V TTL levels supports integration with PCI-class and legacy 5 V logic systems.
• Deterministic Embedded Logic — Nonvolatile single-chip FPGA and deterministic timing characteristics suit embedded control and custom logic functions that require predictable behavior at power-up.
• Board-Level Integration — Power-up/down friendliness and wide supply-voltage range reduce BOM complexity for mixed-voltage systems where configurability and board-level robustness are required.

Unique Advantages

• Nonvolatile Configuration: Eliminates external configuration memory and simplifies system power sequencing and board layout.
• Wide Supply Range and I/O Flexibility: 2.25 V to 5.25 V supply range and configurable I/Os with 5 V tolerance enable mixed-voltage system designs and interfacing to legacy logic levels.
• Extended Temperature Operation: Military temperature grade and −55 °C to +125 °C rating support deployment in harsh and high-reliability environments.
• In-System Diagnostics and Testability: Boundary-scan (JTAG) support and series diagnostic tools provide visibility into device operation and aid production test and field diagnostics.
• Security for IP Protection: Series secure programming (FuseLock™) helps protect design intellectual property on-device.
• Compact, Surface-Mount Packaging: 100-LQFP (14 × 14 mm) footprint balances pin count and board space for compact system designs.
