A54SX32-2TQG144

The A54SX32-2TQG144 is an SX-family, nonvolatile FPGA from Microchip Technology offered in a 144-pin LQFP surface-mount package. It delivers mid-density programmable logic — approximately 48,000 system gates with 2,880 logic elements — and 113 user I/O pins for flexible system integration.

Designed for commercial-grade applications, the device supports mixed-voltage I/O, hot-swap friendliness, and deterministic timing, making it suited for interface bridging, system control, and mid-density logic integration where a compact, single-chip programmable solution is required.

Key Features

• Core and Performance — Approximately 48,000 system gates and 2,880 logic elements provide mid-density programmable logic. Series documentation indicates up to 250 MHz system performance and up to 350 MHz internal performance.
• User I/O and Voltage Support — 113 user-programmable I/O pins with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2. Devices support mixed-voltage operation (2.5 V, 3.3 V, and 5 V) with 5 V input tolerance and 5 V drive strength.
• Nonvolatile, Single-Chip Configuration — Nonvolatile single-chip architecture removes the need for external configuration memory and enables immediate configuration at power-up.
• Power and I/O Robustness — Hot-swap compliant I/Os and power-up/power-down friendliness (no sequencing required for supply voltages) simplify system power management and board-level design.
• Packaging and Mounting — 144-LQFP surface-mount package (supplier package listed as 144-TQFP, 20×20 mm) provides a compact footprint with 113 accessible I/Os.
• System Interoperability — 66 MHz PCI compliance and individual output slew-rate control support reliable interfacing with standard buses and peripherals.
• Design Security and Test — Series features include secure programming technology (FuseLock) and boundary-scan testing compliant with IEEE 1149.1 (JTAG) for manufacturing testability and IP protection.
• Diagnostics and Timing Control — Series-level support for in-system diagnostic and verification tools and deterministic, user-controllable timing.
• Electrical and Environmental — Voltage supply range of 3 V to 5.25 V, commercial operating temperature range of 0 °C to 70 °C, and RoHS compliance.

Typical Applications

• Interface Bridging and Bus Logic — Use the device for PCI-capable interface logic and mixed-voltage bridging where 66 MHz PCI compliance and configurable I/O voltages are required.
• Embedded Control and Glue Logic — Mid-density programmable logic and 113 I/Os make the FPGA well suited for consolidating glue logic, control engines, and signal routing in compact systems.
• In-System Verification and Diagnostics — Built-in support for boundary-scan (JTAG) and series diagnostic tools enables in-system testing and verification during development and production.
• Secure FPGA-Based Designs — Secure programming features such as FuseLock protect design intellectual property in applications where code protection is required.

Unique Advantages

• Flexible Mixed-Voltage I/O: Configurable I/O standards and 5 V tolerance reduce the need for external level-shifters and simplify multi-voltage system designs.
• Single-Chip Nonvolatile Configuration: Eliminates external configuration memory and speeds system bring-up while reducing BOM complexity.
• Deterministic Timing Control: User-controllable timing and support for high internal and system frequencies enable predictable timing closure for critical paths.
• Compact, Mid-Density Integration: Approximately 48,000 system gates and 2,880 logic elements in a 144-LQFP package deliver a balance of logic resources and small board footprint.
• Built-In Testability and Security: Boundary-scan support and secure programming technology provide manufacturing test access and IP protection without adding external components.
• Commercial-Grade Reliability: Designed and specified for commercial temperature operation (0 °C to 70 °C) with RoHS compliance for regulatory alignment.
