A54SX08A-2TQ144

The A54SX08A-2TQ144 is a nonvolatile SX-A family FPGA from Microchip Technology provided in a 144-pin LQFP package. It delivers 12,000 system gates and 768 logic elements with up to 113 user I/Os, targeting applications that require flexible mixed-voltage I/O, in-system programmability and compact package integration.

Designed for commercial-temperature systems, the device supports a wide supply range (2.25 V to 5.25 V) and offers deterministic timing and in-system diagnostic capabilities for reliable integration into embedded and interface designs.

Key Features

• Core Capacity – 12,000 system gates and 768 logic elements provide mid-range programmable logic for glue logic, protocol bridging and control functions.
• Performance – Documented SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical logic paths.
• I/O Flexibility – Up to 113 user I/Os with configurable support for mixed-voltage operation (2.5 V, 3.3 V and 5 V) and 5 V tolerant inputs; suitable for interfacing legacy and modern logic levels.
• Nonvolatile Single-Chip – Single-chip, nonvolatile FPGA architecture removes the need for external configuration memory and simplifies board-level design.
• Power and Reliability – Power-up/power-down friendly operation with no required supply sequencing and hot-swap compliant I/Os to aid system robustness.
• Security and Test – Features secure programming technology and support for boundary-scan (IEEE 1149.1) for design protection and testability.
• Package and Mounting – Available in a 144-pin LQFP (supplier designation 144-TQFP 20×20) surface-mount package for compact board layouts.
• Commercial Temperature Grade – Rated for 0 °C to 70 °C operation and offered in RoHS-compliant packaging.

Typical Applications

• Mixed-Voltage Interface Bridging – Use the device to bridge and adapt signals between 2.5 V, 3.3 V and 5 V domains, including support for 5 V tolerant I/Os.
• PCI and Legacy Peripheral Logic – Applicable in 66 MHz PCI-compliant subsystems and peripheral logic given the SX-A family’s PCI support.
• In-System Programmable Logic – Deploy as on-board, reprogrammable logic for prototyping, firmware-updatable control functions and product refinement without external configuration components.
• Compact Embedded Systems – Integration into space-constrained designs that require nonvolatile logic and up to 113 user I/Os in a 144-pin LQFP package.

Unique Advantages

• Flexible I/O Voltage Support: Mixed-voltage operation (2.5 V, 3.3 V, 5 V) and 5 V tolerant inputs simplify interfacing across legacy and modern circuits.
• Nonvolatile, Single-Chip Solution: Eliminates external configuration memory, reducing BOM complexity and board-level components.
• Deterministic Timing Control: User-controllable timing features enable predictable timing closure for deterministic system behavior.
• Built-In Test and Security: Boundary-scan support and secure programming technology provide testability and protection against reverse engineering.
• Compact Package: 144-pin LQFP surface-mount package allows high I/O count and logic capacity in a compact footprint.
