A54SX32-1TQ144

The A54SX32-1TQ144 is a commercial-grade SX family FPGA provided by Microchip Technology. It delivers approximately 48,000 system gates implemented across 2,880 logic elements and exposes 113 user-configurable I/O pins in a 144-pin LQFP surface-mount package.

Designed as a nonvolatile, single-chip FPGA solution, the device supports mixed-voltage operation and configurable I/Os, making it suitable for a range of commercial embedded and logic-integration tasks where predictable timing, flexible I/O, and compact packaging are required.

Key Features

• Core Capacity  Approximately 48,000 system gates implemented as 2,880 logic elements, providing substantial programmable logic for glue logic, control, and medium-complexity designs.
• Logic Performance  Family-level performance targets include up to 250 MHz system performance and up to 350 MHz internal performance; this specific part uses the -1 speed grade to deliver an approximate 15% improvement over standard speed.
• I/O Flexibility  113 user I/O pins with configurable I/O options and support for mixed-voltage signaling; datasheet describes support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 interfaces and 5 V input tolerance/drive characteristics.
• Nonvolatile Single-Chip Architecture  Nonvolatile configuration stored on-chip eliminates the need for external configuration memory and simplifies system power-up behavior.
• Power and Voltage  Operates from a 3 V to 5.25 V supply range and is power-up/down friendly with no supply sequencing required per device guidance.
• Package and Mounting  144-pin LQFP (surface-mount) package; supplier device package listed as 144-TQFP (20×20) for board-level mounting and compact PCB footprint.
• Commercial Temperature Grade  Rated for commercial operation from 0 °C to 70 °C.
• System-Level Features  Includes hot-swap compliant I/Os, 66 MHz PCI compliance at the family level, deterministic timing controls, boundary-scan (IEEE 1149.1) support, and in-system diagnostic/verification capability as described in family documentation.
• Security and Test  Family documentation cites secure programming technology (FuseLock™) to protect programmed designs and boundary-scan for manufacturing test.
• Regulatory  RoHS compliant.

Typical Applications

• Embedded System Control  Use the device’s 2,880 logic elements and 113 I/Os for control logic, glue logic, and interface handling in commercial embedded systems.
• Interface Bridging  Configurable I/O voltage support and 5 V tolerance enable the FPGA to serve as an interface bridge between mixed-voltage subsystems.
• Board-Level Logic Consolidation  Nonvolatile single-chip configuration and compact 144-LQFP packaging allow consolidation of discrete logic into a single programmable device for space- and BOM-constrained designs.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates external configuration memory and simplifies system power-up sequencing and BOM.
• Mixed-voltage I/O support: Flexible I/O standards and 5 V tolerance reduce the need for level translators when interfacing with legacy and modern logic levels.
• Predictable performance: Family-level deterministic timing and defined speed-grade options (the -1 speed grade delivers approximately 15% faster performance than standard) support controlled timing designs.
• Compact surface-mount package: 144-pin LQFP provides a balance of I/O count and small board footprint for commercial applications.
• Design protection and testability: Secure programming technology and IEEE 1149.1 boundary-scan support add security and ease manufacturing test integration.
• RoHS compliance: Meets lead-free environmental requirements for commercial products.
