A54SX32A-2TQ100

The A54SX32A-2TQ100 is a commercial-grade SX-A family FPGA from Microchip Technology supplied in a 100-pin thin quad flat package (100-LQFP / 100-TQFP 14×14). It provides a nonvolatile, single-chip FPGA solution with 2,880 logic elements and approximately 48,000 system gates, making it suitable for board-level logic integration and mixed-voltage interface tasks.

With 81 user I/Os, flexible I/O standards and a wide supply range, this device targets embedded systems and PCI-capable applications that require on-chip configuration retention, predictable timing and in-system testability while operating across a 2.25 V to 5.25 V supply range within a 0 °C to 70 °C commercial temperature window.

Key Features

• Core Capacity — 2,880 logic elements and approximately 48,000 system gates provide substantial programmable logic for moderate-complexity designs.
• I/O Flexibility — 81 user I/Os with SX-A family 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.
• Nonvolatile Single-Chip Architecture — SX-A family nonvolatile configuration removes the need for external configuration memory devices.
• Performance — SX-A family performance targets include 250 MHz system performance and up to 350 MHz internal performance; devices are 66 MHz PCI compliant.
• Power and Robustness — 2.25 V to 5.25 V supply range and power-up/power-down friendly I/Os that do not require supply sequencing.
• Package and Mounting — Surface-mount 100-LQFP package (supplier device package: 100-TQFP, 14×14) for compact PCB layouts.
• Test and Security — Boundary-scan testing (IEEE 1149.1 JTAG) and SX-A family features such as in-system diagnostics with Silicon Explorer II and Actel FuseLock secure programming technology.
• Environmental Compliance — RoHS compliant and specified for commercial-grade operation (0 °C to 70 °C).

Typical Applications

• PCI-based embedded systems — 66 MHz PCI compliance and configurable PCI I/O standards make the device suitable for interfacing with PCI components and system-level I/O.
• Mixed-voltage interface and glue logic — Mixed-voltage operation and flexible I/O standards enable bridging and glue logic between subsystems operating at 2.5 V, 3.3 V and 5 V.
• Nonvolatile FPGA designs — Single-chip nonvolatile configuration is useful where on-board configuration memory is undesirable or space is limited.
• Boards requiring boundary-scan testability — Built-in JTAG boundary-scan facilitates board-level testing and manufacturing diagnostics.

Unique Advantages

• Single-chip nonvolatile solution: Eliminates the need for external configuration ROM, simplifying BOM and board design.
• Flexible I/O and mixed-voltage support: Configurable I/O standards and 5 V input tolerance reduce the need for level translators in many designs.
• Significant logic resources: 2,880 logic elements and ~48,000 system gates provide headroom for moderate-density logic implementations.
• Power-up robustness: Power-up/power-down friendly I/Os remove sequencing constraints on supply rails.
• Compact, surface-mount footprint: 100-LQFP / 100-TQFP (14×14) package optimizes PCB area for space-constrained applications.
• Built-in test and device security: JTAG boundary-scan and FuseLock secure programming support production testing and IP protection.
