A54SX32A-1TQ144I

The A54SX32A-1TQ144I is an SX-A family FPGA from Microchip Technology offering a nonvolatile, single‑chip programmable logic solution in a 144‑pin LQFP package. With 48,000 system gates and 2,880 logic elements, this industrial‑grade device targets applications that require flexible, deterministic digital logic in harsh temperature environments.

Built for mixed‑voltage I/O and in‑system programmability, the device supports a broad supply range and features designed for reliable power sequencing, security and boundary‑scan testing, making it suitable for embedded control, interface and I/O customization tasks.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements provide significant programmable logic density for glue logic, protocol bridging and custom datapath implementations.
• I/O and Voltage Flexibility — 113 user I/Os with configurable I/O support for multiple signaling environments; devices in the SX‑A family support 2.5 V, 3.3 V and 5 V mixed‑voltage operation, with 5 V input tolerance and drive strength options.
• Performance — SX‑A family performance targets include 250 MHz system performance and up to 350 MHz internal performance (family specification); the part number includes a –1 speed grade for increased performance relative to standard speed.
• Package and Mounting — Delivered in a 144‑LQFP surface‑mount package (supplier package: 144‑TQFP, 20×20 mm) suitable for compact board designs.
• Industrial Temperature Grade — Rated for operation from –40 °C to +85 °C, supporting industrial applications and environments.
• Nonvolatile Single‑Chip Configuration — Single‑chip, nonvolatile configuration simplifies system design by eliminating external configuration memory and providing power‑up/power‑down friendly behavior without supply sequencing.
• Security and Test — Includes Actel Secure Programming Technology with FuseLock™ to protect design IP and supports IEEE 1149.1 boundary‑scan (JTAG) for manufacturing test and in‑system diagnostics.
• System Diagnostics and Tool Support — Family‑level support for in‑system diagnostic and verification via Silicon Explorer II (as specified for the SX‑A family).
• Regulatory — RoHS compliant.

Typical Applications

• Industrial control and automation — Implement custom control logic, signal conditioning interfaces and state machines that require industrial temperature operation and flexible I/O.
• Embedded system glue logic — Replace discrete glue components with compact, reprogrammable logic for protocol conversion, bus interfacing and timing control.
• PCI and legacy interface bridging — SX‑A family devices include PCI compliance (66 MHz) and configurable I/O support for 3.3 V/5 V PCI signaling, enabling interface bridging and expansion tasks.
• Communications and instrumentation — Use the device for protocol handling, parallel/serial interface adaptation and deterministic timing functions within measurement and communications equipment.

Unique Advantages

• Single‑chip nonvolatile configuration: Eliminates the need for external configuration memory, simplifying BOM and board layout.
• Flexible mixed‑voltage I/O: Supports multiple I/O voltage standards and 5 V input tolerance for broad compatibility with legacy and modern interfaces.
• Industrial temperature rating: Rated –40 °C to +85 °C to meet the demands of industrial application environments.
• Security features: FuseLock™ secure programming protects intellectual property and helps prevent reverse engineering.
• In‑system diagnostics and testability: Boundary‑scan (IEEE 1149.1) and family‑level diagnostic tools support manufacturing test and in‑field verification.
• Compact package: 144‑LQFP surface‑mount package offers a balance of pin count and board area for space‑constrained designs.
