A54SX08A-TQ144

The A54SX08A-TQ144 is a member of the SX-A family of Field Programmable Gate Arrays (FPGAs) from Microchip Technology. It provides a nonvolatile, single-chip FPGA solution with 12,000 system gates and 768 logic elements, delivered in a 144‑pin thin quad flat pack (TQFP) surface-mount package.

Designed for commercial-grade applications, the device combines mixed-voltage I/O flexibility, hot-swap–capable I/Os and deterministic timing options from the SX-A architecture, making it suitable for embedded logic, interface bridging and compact system designs that require a reprogrammable, nonvolatile solution.

Key Features

• Core Performance  SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as specified for the family.
• Logic Capacity  Approximately 12,000 system gates and 768 logic elements provide mid-range integration for glue logic, control and interface functions.
• User I/O and Configurability  Provides 113 user-programmable I/Os in the 144‑pin TQFP package. Family-level I/O features include configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signalling, with selectable pull-up/pull-down on power‑up and individual output slew control.
• Mixed-Voltage and I/O Tolerance  Supports mixed 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance and 5 V drive strength options (family-level capability).
• Nonvolatile Single-Chip Solution  Nonvolatile configuration on a single device removes the need for external configuration memory and simplifies system start-up.
• System and Test Support  Family includes boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic capabilities for verification.
• Package and Supply  Surface-mount 144‑pin TQFP (20 × 20 mm) package; voltage supply range 2.25 V to 5.25 V; commercial operating temperature 0 °C to 70 °C.
• Security  Family-level secure programming technology (FuseLock) helps protect intellectual property and prevent reverse engineering.

Typical Applications

• Embedded control and glue logic  Use the A54SX08A-TQ144 to consolidate discrete logic, state machines and control functions into a single, reprogrammable device.
• Interface bridging and protocol adaptation  Mixed-voltage I/O support and configurable I/O standards make the device suitable for interfacing between legacy and modern logic levels and protocols.
• Compact board-level FPGA integration  The 144‑pin TQFP package and mid-range gate count are well suited to space-constrained commercial systems that require on-board reprogrammability without external configuration memory.
• PCI and peripheral control  Family features include 66 MHz PCI compliance and hot-swap–capable I/Os, enabling use in I/O and peripheral interface roles on commercial boards.

Unique Advantages

• Nonvolatile single-chip architecture: Eliminates external configuration memory and simplifies power-up sequencing for cleaner board-level design.
• Flexible mixed-voltage I/Os: Configurable support for multiple I/O standards and 5 V tolerance enables seamless interfacing across different logic families.
• Mid-range integration in a compact package: 12,000 system gates and 768 logic elements in a 144‑pin TQFP make the device a good fit for space-conscious commercial applications.
• Deterministic timing and system-level diagnostics: Family-level timing control and in-system verification capabilities facilitate reliable system behavior and easier validation.
• Commercial temperature and supply flexibility: 0 °C to 70 °C operating range and 2.25 V to 5.25 V supply range support a variety of commercial product designs.
