A54SX08A-TQ100I

The A54SX08A-TQ100I is an industrial-grade SX-A family FPGA from Microchip Technology provided in a 100-pin LQFP package. It delivers a nonvolatile, single-chip FPGA solution with 12,000 system gates and 768 logic elements for implementing glue logic, control functions and interface logic in industrial and embedded systems.

Built for mixed-voltage designs and PCI-capable systems, this device combines configurable I/O, deterministic timing features and in-system diagnostic support to simplify system integration and field verification.

Key Features

• Core Performance (SX-A family)  Family-level performance includes up to 250 MHz system performance and up to 350 MHz internal performance, enabling responsive application-level logic and timing.
• Logic Resources  12,000 system gates and 768 logic elements provide capacity for mid-range logic implementations and control functions.
• I/O and Voltage Flexibility  81 user I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• No Embedded RAM  Total on-chip RAM bits: 0 — useful to plan external memory if required by the design.
• Power and Hot-Swap Friendly  2.25 V to 5.25 V supply range and power-up/down friendly behavior (no supply sequencing required). I/Os are hot-swap compliant.
• Security and Testability  Nonvolatile single-chip architecture with Actel Secure Programming Technology (FuseLock™) to protect intellectual property; boundary-scan testing supported (IEEE 1149.1 JTAG).
• Package and Temperature  100-pin LQFP package (supplier device package listed as 100-TQFP 14×14) and industrial temperature grade: -40 °C to +85 °C.
• In-System Diagnostics  Family supports in-system diagnostic and verification capability (Silicon Explorer II) for field verification and debugging.
• Standards Support  SX-A family devices support 66 MHz PCI compliance and deterministic, user-controllable timing for predictable system behavior.
• RoHS Compliant  Device is RoHS compliant.

Typical Applications

• Industrial control and automation  Use the A54SX08A-TQ100I for control logic, I/O interfacing and deterministic timing in industrial systems operating across -40 °C to +85 °C.
• PCI and legacy-system interfaces  The device’s 66 MHz PCI compliance and configurable I/O levels make it well suited for PCI-compliant interface functions and legacy bus bridging.
• Embedded glue logic  Implement board-level glue logic, protocol adaptation and peripheral control where a nonvolatile single-chip FPGA simplifies the bill of materials.
• Field-updatable systems  In-system diagnostic and verification capabilities support field updates and hardware verification during maintenance operations.

Unique Advantages

• Nonvolatile single-chip design: Eliminates external configuration memory and simplifies system boot-up and supply sequencing.
• Mixed-voltage I/O flexibility: Configurable I/O standards and 5 V tolerance reduce level-shifting components and ease integration with diverse peripherals.
• Industrial temperature rating: Rated for -40 °C to +85 °C operation, supporting deployment in industrial environments.
• Security features: FuseLock™ programming technology for protection against reverse engineering and design theft.
• Testability and diagnostics: Boundary-scan (IEEE 1149.1) and in-system diagnostic support aid manufacturing test and field verification.
• Wide supply tolerance: Operation from 2.25 V to 5.25 V for flexible power-rail integration.
