A54SX08A-1TQG100I

The A54SX08A-1TQG100I is a member of the SX-A family of nonvolatile FPGAs from Microchip Technology. It delivers a compact, single-chip programmable logic solution with approximately 12,000 system gates and 768 logic elements for control, glue-logic and mid-density digital designs.

Designed for industrial-temperature operation and mixed-voltage designs, this device targets embedded systems that require flexible I/O, in-system programmability and deterministic timing in a 100-pin thin/LQFP footprint.

Key Features

• Logic Capacity – Approximately 12,000 system gates with 768 logic elements (logic modules) to implement mid-density combinational and sequential logic.
• I/O and Package – 81 user I/Os in a 100-pin LQFP package; supplier device package listed as 100-TQFP (14×14), surface-mount mounting type.
• Voltage Flexibility – 2.25 V to 5.25 V supply range supporting mixed-voltage operation and 5 V input tolerance where applicable.
• Performance – SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family-level data).
• Nonvolatile Single-Chip Solution – On-chip nonvolatile configuration removes the need for external configuration memory (family-level feature).
• I/O and System Features – Family-level features include hot-swap compliant I/Os, configurable I/O support for multiple standards (3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, 2.5 V LVCMOS2), configurable pull-ups/pull-downs, individual output slew rate control, and 5 V drive strength where supported.
• Diagnostics and Test – Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability (family-provided Silicon Explorer II support noted in documentation).
• Security – Family-level secure programming technology (FuseLock™) to protect designs against reverse engineering (as documented for the SX-A family).
• Environment and Reliability – Industrial temperature grade (–40 °C to +85 °C) and RoHS compliant.

Typical Applications

• PCI and Bus Interfaces – The SX-A family's 66 MHz PCI compliance and configurable I/O support make the device suitable for PCI-based interface logic and bus-bridging functions.
• Industrial Control – Industrial-temperature rating and flexible I/O voltages enable use in control, automation and board-level logic within industrial systems.
• In-System Programmable Logic – Nonvolatile single-chip configuration and boundary-scan support are useful for in-field updates, diagnostics and system verification workflows.

Unique Advantages

• Nonvolatile Configuration: Single-chip nonvolatile FPGA architecture eliminates external configuration memory and simplifies board BOM and startup behavior.
• Mixed-Voltage I/O Flexibility: Configurable I/O standards and 5 V tolerance support integration with 5 V and 3.3 V subsystems without additional level-shifting hardware.
• Industrial Temperature Range: Rated for –40 °C to +85 °C operation, enabling deployment in temperature-variable embedded and industrial environments.
• Compact, Surface-Mount Package: 100-pin LQFP/TQFP surface-mount package provides a small footprint option for space-constrained PCBs.
• Security and Testability: Family-level FuseLock secure programming and IEEE 1149.1 boundary-scan support help protect IP and facilitate board-level testing.
• Deterministic Performance: Documented family-level internal and system performance characteristics that support predictable timing for critical logic paths.
