A54SX32-1BGG329

The A54SX32-1BGG329 is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It offers a mid-range logic capacity and abundant I/O in a compact 329-ball BGA package, suited for embedded designs requiring reprogrammable logic, configurable I/O and secure in-system programming.

Key Features

• Core Performance Family-level performance up to 250 MHz system performance and up to 350 MHz internal performance as documented for the SX-A family.
• Logic Capacity Approximately 48,000 system gates and 2,880 logic elements, providing substantial programmable logic for mid-complexity designs.
• I/O and Interfacing 249 user I/O pins with configurable I/O support for multiple voltage standards (3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, 2.5 V LVCMOS2), 5 V input tolerance and selectable slew/drive control.
• Nonvolatile, Single-Chip Nonvolatile, single-chip architecture removes the need for external configuration memory and enables immediate operation after power-up without configuration sequencing.
• Voltage and Power Operates across a broad supply range of 3 V to 5.25 V to support mixed-voltage systems and flexible board-level power architectures.
• Package and Mounting 329-ball PBGA package (329-PBGA, 31×31) in a surface-mount form factor for dense board integration.
• Security and Testability Built-in Actel Secure Programming Technology (FuseLock™) to help protect design IP, plus IEEE 1149.1 boundary-scan (JTAG) support and in-system diagnostic capability.
• Standards and Reliability Features such as hot-swap compliant I/Os, power-up/power-down friendly operation (no sequencing required for supply voltages), and 66 MHz PCI compliance at the family level.
• Environmental Compliance RoHS compliant packaging (G option available) to meet regulatory and assembly requirements.
• Operating Grade Commercial temperature grade rated for 0 °C to 70 °C.

Typical Applications

• Embedded system logic — Implements glue logic, protocol bridging and custom control functions using the device’s 2,880 logic elements and abundant I/O.
• PCI-based peripherals — Suitable for 66 MHz PCI-compliant board-level designs that require reprogrammable logic and mixed-voltage I/O support.
• Secure configuration and IP protection — Ideal for applications that need on-board, nonvolatile programmability combined with design protection via FuseLock.
• In-system diagnostics and development — Supports boundary-scan and in-system diagnostic tools for board bring-up, verification and field diagnostics.

Unique Advantages

• Highly integrated, nonvolatile solution: Single-chip FPGA architecture eliminates external configuration memory and simplifies BOM and board layout.
• Flexible mixed-voltage I/O: Configurable support for 2.5 V, 3.3 V and 5 V signaling with 5 V input tolerance enables direct interfacing to a wide range of peripherals and legacy logic.
• Secure programming and IP protection: FuseLock™ secure programming reduces risk of reverse engineering and helps protect proprietary designs in the field.
• Compact BGA packaging: 329-ball PBGA in a surface-mount form factor supports high I/O density in space-constrained systems.
• Design-for-test and diagnostics: IEEE 1149.1 boundary-scan and in-system diagnostic capabilities speed board-level testing and troubleshooting.
• Regulatory readiness: RoHS-compliant packaging option supports environmentally driven assembly and procurement requirements.
