A54SX32A-1TQ144

The A54SX32A-1TQ144 is a Microchip Technology SX-A family FPGA in a 144-pin LQFP package, offering 48,000 system gates and 2,880 logic elements for mid-range programmable logic designs. It provides 113 user I/Os with configurable I/O support and a wide supply voltage range, making it suitable for commercial embedded control, interface bridging, and in-system programmable applications.

This device is a nonvolatile, single-chip FPGA solution with hot-swap compliant I/Os and features intended to simplify mixed-voltage designs and system integration while operating across a 2.25 V to 5.25 V supply range and a commercial temperature range of 0 °C to 70 °C.

Key Features

• Core capacity — 48,000 system gates and 2,880 logic elements provide substantial programmable logic resources for combinatorial and registered logic functions.
• User I/O — 113 user-programmable I/Os in a 144-LQFP package; I/Os are hot-swap compliant and support configurable pull-up/pull-down behavior at power-up.
• Nonvolatile single-chip — On-chip nonvolatile configuration eliminates the need for external configuration memory and supports single-chip system deployment.
• Mixed-voltage I/O and 5 V tolerance — Configurable I/O supports 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, enabling mixed-voltage system designs and 5 V input tolerance.
• Deterministic timing and performance — Series-level performance targets include up to 250 MHz system performance and up to 350 MHz internal performance, plus user-controllable timing for predictable behavior.
• System-level features — Boundary-scan (IEEE 1149.1) JTAG support, in-system diagnostic and verification capability, and secure programming technology to protect design IP.
• Package and mounting — Surface-mount 144-LQFP (thin TQFP form factor noted as 144-TQFP 20×20) for compact board implementation.
• Supply and environmental — Operates from 2.25 V to 5.25 V and is RoHS compliant; rated for commercial temperature operation from 0 °C to 70 °C.

Typical Applications

• Peripheral and interface bridging — Configurable I/O standards and PCI support enable bridging between legacy and modern interfaces.
• Embedded control and glue logic — Logic capacity and plentiful I/Os support custom control functions, state machines, and board-level integration.
• In-system programmable designs — Nonvolatile single-chip configuration and in-system diagnostic capabilities facilitate field updates and verification.
• Security-sensitive applications — Built-in secure programming technology helps protect designs from reverse engineering and unauthorized access.

Unique Advantages

• High logic density: 48,000 system gates and 2,880 logic elements deliver ample capacity for moderate-complexity FPGA implementations without external glue logic.
• Flexible mixed-voltage I/O: Support for multiple I/O standards and 5 V tolerance reduces external level-shifting and simplifies integration with diverse peripherals.
• Nonvolatile configuration: Single-chip, nonvolatile architecture removes the need for external configuration memory and simplifies power-up sequencing.
• Deterministic performance: User-controllable timing and series-level MHz performance figures support predictable, timing-sensitive designs.
• Board-level friendliness: Hot-swap compliant I/Os and configurable power-up I/O states improve robustness during board integration and system bring-up.
• Compliance and environmental: RoHS compliance supports modern environmental requirements for commercial deployments.
