A54SX08A-1TQ100

The A54SX08A-1TQ100 is a member of the SX-A family of nonvolatile Field Programmable Gate Arrays from Microchip Technology. It provides approximately 12,000 system gates and 768 logic elements in a compact 100-pin LQFP footprint, delivering reprogrammable logic and flexible I/O for mixed-voltage designs.

Designed for applications that require a single-chip, nonvolatile FPGA with configurable I/O and deterministic timing features, the device supports a wide supply range and commercial temperature operation, making it suitable for a variety of embedded and interface logic tasks.

Key Features

• Logic Capacity — 12,000 system gates with 768 logic elements to implement medium-complexity logic, glue logic, and control functions.
• I/O and Package — 81 user I/Os in a 100-LQFP package (supplier device package listed as 100-TQFP, 14×14). I/O count supports mixed-signal interfacing on a small board footprint.
• Voltage Flexibility — Wide supply range from 2.25 V to 5.25 V to accommodate mixed-voltage system environments and I/O standards.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as documented for the family.
• Nonvolatile Single-Chip Architecture — Single-chip, nonvolatile configuration for designs that require retained configuration without external memory.
• I/O and System Features — Hot-swap compliant I/Os, configurable I/O support for multiple voltage standards, power-up/down friendly operation (no supply sequencing required), and individual output slew rate control.
• Design Security and Testability — Includes Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering and supports boundary-scan testing compliant with IEEE 1149.1 (JTAG).
• Commercial Temperature Grade — Rated for operation from 0 °C to 70 °C, suitable for commercial applications.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• PCI and Interface Logic — 66 MHz PCI compliance and configurable I/O voltage support make this FPGA suitable for interface bridging and PCI-related glue logic.
• Mixed-Voltage Embedded Systems — Wide supply range and configurable I/Os allow integration into systems that combine 5 V, 3.3 V and lower-voltage domains.
• Nonvolatile Control and Glue Logic — Single-chip nonvolatile configuration supports applications that require retained FPGA configuration without external configuration memory.
• Boundary-Scan and In-System Diagnostics — Built-in JTAG boundary-scan capability and family support for in-system diagnostic tools assist in board-level test and verification workflows.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates the need for external configuration memory while simplifying system design and startup behavior.
• Flexible I/O and mixed-voltage support: Supports multiple I/O voltage standards and a wide supply range (2.25 V–5.25 V), enabling use across diverse interface requirements.
• Compact package with ample I/O: 81 user I/Os in a 100-pin LQFP package balance board-level density with connectivity for peripherals and interfaces.
• Design security built in: FuseLock technology offers protection against reverse engineering and unauthorized access to programmed design data.
• Manufacturing and test friendliness: Boundary-scan (IEEE 1149.1) support and hot-swap compliant I/Os facilitate production test and field maintenance.
• Commercial-grade operation: Specified for 0 °C to 70 °C operation, appropriate for commercial embedded applications.
