A54SX32-1TQ144M

The A54SX32-1TQ144M is a nonvolatile SX family FPGA from Microchip Technology supplied in a 144‑pin LQFP surface-mount package. It delivers 48,000 system gates and 2,880 logic elements with 113 user I/O pins, making it suitable for designs that require on-chip programmability, mixed-voltage interfacing and robust temperature performance.

Designed for applications requiring military-grade operation, the device supports a wide supply range (3 V to 5.5 V), a military operating temperature range (–55 °C to 125 °C) and RoHS compliance, and includes family-level features such as deterministic timing, secure programming and in-system diagnostic capability.

Key Features

• Core and Capacity 48,000 system gates and 2,880 logic elements provide a mid-range integration point for control, glue-logic and custom digital functions.
• User I/O and Package 113 user-programmable I/O pins in a 144‑LQFP surface-mount package support dense board integration and signal routing.
• Voltage and I/O Flexibility Supports mixed-voltage operation across 2.5 V, 3.3 V and 5 V domains with 5 V input tolerance and selectable I/O standards, enabling direct interfacing to legacy and modern logic levels.
• Performance (SX-A family) Family-level performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (SX-A family specification).
• Nonvolatile Single-Chip Configuration Nonvolatile on-chip configuration removes the need for external configuration memory and simplifies startup sequencing—power‑up/power‑down friendly with no supply sequencing required (SX-A family).
• Reliability and Test Hot-swap compliant I/Os, boundary-scan (IEEE 1149.1) support and configurable pull-up/pull-down behavior aid board-level integration, testability and reliability.
• Security and Diagnostics Family features include secure programming (FuseLock™) and in-system diagnostic/verification capability for design protection and field verification.
• Environment and Compliance Military grade (-55 °C to 125 °C), RoHS compliant and surface-mount packaged for industry-standard assembly processes.
• Memory No embedded RAM bits are provided in this device, consistent with its dedicated flip-flop and logic-element architecture.

Typical Applications

• Military and Harsh-Environment Systems — Military temperature grade and broad supply tolerance make the device suitable for rugged systems requiring reliable digital logic and interfacing.
• Mixed-Voltage Interface Bridging — Flexible I/O standards and 5 V tolerance enable level translation and interfacing between legacy 5 V logic and lower-voltage domains without additional translators.
• Secure Configuration and Field Diagnostics — Built-in secure programming and in-system diagnostic capabilities support designs that require configuration protection and field verification.
• Control and Glue Logic — The combination of 2,880 logic elements and deterministic timing is well suited to control, protocol bridging and custom glue‑logic functions on compact PCBs.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates the need for external configuration memory, simplifying BOM and system startup sequencing.
• Mixed-voltage I/O support: Native support for 2.5 V, 3.3 V and 5 V I/O (with 5 V tolerance) reduces external level-shifting components and speeds integration with diverse peripherals.
• Military-grade thermal performance: Rated for –55 °C to 125 °C, enabling deployment in temperature‑extreme environments without additional thermal qualification.
• Deterministic timing and high internal performance: Family-level timing control and multi-hundred-MHz internal performance support tightly controlled timing paths and higher-speed internal logic.
• Security and testability built in: FuseLock™ secure programming and IEEE 1149.1 boundary-scan support help protect intellectual property and simplify manufacturing test.
