A54SX32-BG329

The A54SX32-BG329 is a commercial-grade SX family FPGA from Microchip Technology. It provides a nonvolatile, single-chip programmable logic solution with 48,000 system gates and approximately 2,880 logic elements aimed at mid-density embedded designs.

Designed for flexible I/O and mixed-voltage systems, the device supports up to 249 user I/Os, a broad 3 V to 5.25 V supply range, and deterministic timing features suitable for PCI-compliant and other mixed-voltage applications within a 0 °C to 70 °C operating range.

Key Features

• Core Performance — Family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical logic.
• Logic Capacity — 48,000 system gates and approximately 2,880 logic elements provide mid-density programmable logic for glue logic, protocol bridging, and control functions.
• I/O and Clock Resources — Up to 249 user I/Os and 3 global clocks enable complex interfacing and synchronous designs; configurable I/O support includes 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling.
• Nonvolatile Configuration — Single-chip, nonvolatile architecture removes the need for external configuration memory and supports in-system programming and diagnostics.
• Power and Voltage — Wide supply range from 3 V to 5.25 V and power-up/power-down friendly behavior with no sequencing required for supply voltages.
• Package and Mounting — 329-BBGA package case (supplier device package: 329-PBGA, 31×31) in a surface-mount form factor suitable for compact board layouts.
• System and Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic capability via Silicon Explorer II for verification and debug.
• Security and Reliability — Actel Secure Programming Technology with FuseLock™ helps protect design IP against reverse engineering and unauthorized access.
• Compliance — RoHS compliant.

Typical Applications

• PCI and Mixed-Voltage Interfaces — Use the A54SX32-BG329 in PCI-compliant peripherals or bridge logic where 3.3 V/5 V PCI signaling and mixed-voltage I/O are required.
• Embedded Control and Glue Logic — Mid-density logic capacity and abundant I/Os make the device suitable for control tasks, protocol translation, and board-level glue logic.
• In-System Diagnostics and Verification — The device’s in-system diagnostic features enable verification and silicon-level debugging during development and deployment.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates external configuration memory and simplifies board-level BOM and startup sequencing.
• Flexible mixed-voltage I/O: Configurable support for multiple logic standards (including 3.3 V/5 V PCI) reduces the need for external level-shifters in mixed-voltage systems.
• Deterministic timing and high internal performance: Up to 350 MHz internal performance and deterministic timing control help meet tight timing budgets.
• Strong on-chip security: FuseLock™ programming protects intellectual property and helps prevent reverse engineering.
• Test and debug support: JTAG boundary-scan and Silicon Explorer II diagnostic support speed validation and reduce development time.
• Commercial temperature and RoHS compliant: Rated for 0 °C to 70 °C operation and RoHS-compliant packaging for general commercial applications.
