A54SX08A-TQ144I

The A54SX08A-TQ144I is an SX-A family, nonvolatile single-chip FPGA offered by Microchip Technology. It delivers 12,000 system gates implemented as 768 logic elements with 113 user I/O pins in a 144-pin thin quad flat pack package.

Designed for industrial-temperature applications, the device supports mixed-voltage I/O, hot-swap–capable interfaces and deterministic timing, making it suitable for industrial control, mixed-voltage system glue logic and PCI-compliant subsystems.

Key Features

• Logic Capacity  768 logic elements (combinatorial cells) providing 12,000 typical system gates for implementing custom logic and control functions.
• I/O and Packaging  113 user I/Os in a 144-LQFP package (supplier device package: 144-TQFP 20×20) for dense board-level integration.
• Performance  System performance up to 250 MHz and internal performance up to 350 MHz as specified for the SX-A family.
• Power and Voltage  Flexible supply range from 2.25 V to 5.25 V with support for 2.5 V, 3.3 V and 5 V mixed-voltage operation and 5 V input tolerance.
• I/O Configurability  Configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; includes individual output slew-rate control and configurable weak pull-up/pull-down at power-up.
• Nonvolatile Single-Chip Solution  On-chip nonvolatile configuration eliminates the need for external configuration memory and simplifies power-up behavior (no supply sequencing required).
• System and Testability  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic capability via Silicon Explorer II.
• Reliability and Security  Hot-swap–compliant I/Os, power-up/power-down friendly operation, and Actel Secure Programming Technology with FuseLock™ for design protection.
• Environmental and Temperature  Industrial grade operation from −40°C to +85°C and RoHS compliant.
• Memory  No embedded RAM (Total RAM bits: 0), suitable for designs that use distributed logic or external memory.

Typical Applications

• Industrial Control and Automation  Implement control logic, interface bridging and deterministic timing functions that benefit from industrial temperature range and mixed-voltage I/O support.
• System Glue and Interface Logic  Provide mixed-voltage level translation, I/O conditioning and protocol glue between 5 V and lower-voltage domains, including PCI-compliant interfaces.
• Embedded Peripheral Controllers  Replace discrete logic for custom peripheral control, leveraging nonvolatile configuration and hot-swap–capable I/Os for robust system behavior.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates external configuration memory and simplifies board design and start-up sequencing.
• Mixed-voltage I/O with 5 V tolerance: Enables direct interfacing to 5 V legacy logic and modern 2.5/3.3 V domains without extra level shifters.
• Deterministic timing and high internal performance: Internal performance up to 350 MHz supports tight timing control for synchronous logic and high-speed internal paths.
• Security and testability built in: FuseLock programming protection and IEEE 1149.1 boundary-scan support facilitate secure deployment and production test.
• Industrial temperature rating: Specified operation from −40°C to +85°C for reliable use in industrial environments.
• Compact BGA/PQFP-compatible packaging: Available in a 144-pin thin QFP that supports high-density PCB layouts and streamlined system integration.

Why Choose A54SX08A-TQ144I?

The A54SX08A-TQ144I balances a compact footprint with a capable logic complement and flexible I/O options, making it an effective choice for industrial designs that require nonvolatile configuration, mixed-voltage interfacing and deterministic timing. Its SX-A family heritage provides documented performance characteristics (250 MHz system / 350 MHz internal) and production-friendly features such as hot-swap I/Os and IEEE 1149.1 boundary-scan.

This device suits engineers and procurement teams building industrial controllers, interface logic boards, and PCI-compliant subsystems who need predictable timing, on-chip security features and stable operation across a −40°C to +85°C temperature range.
