A54SX32A-2BG329I

The A54SX32A-2BG329I is an industrial-grade SX-A family FPGA from Microchip Technology. It delivers a nonvolatile, single-chip FPGA architecture with 48,000 system gates, 2,880 logic elements and up to 249 user-programmable I/O pins.

Designed for mixed-voltage embedded and industrial designs, this device supports a wide supply range (2.25 V to 5.25 V) and an operating temperature of −40 °C to 85 °C, making it suitable for deployments that require high I/O density, configurable I/O standards and secure, in-system programmability.

Key Features

• Performance: SX-A family performance metrics include up to 250 MHz system performance and 350 MHz internal performance (series-level specification).
• Capacity: 48,000 system gates with 2,880 logic elements and device-level support for a large number of registers and flip-flops appropriate to the A54SX32A class.
• I/O and Voltage Support: 249 user I/Os with configurable I/O support for multiple standards; device-level mixed-voltage operation and a supply range of 2.25 V to 5.25 V enable flexible interfacing.
• No Embedded RAM: Total on-chip RAM bits reported as 0, for designs that rely on logic and external memory resources.
• Secure, Nonvolatile Configuration: Nonvolatile single-chip FPGA architecture and Actel Secure Programming Technology with FuseLock™ to protect designs against reverse engineering (series-level feature).
• System Integration and Reliability: Hot-swap–compliant I/Os, power-up/power-down friendly operation without supply sequencing, boundary-scan (IEEE 1149.1 JTAG) and deterministic, user-controllable timing.
• I/O Control and Flexibility: Configurable weak pull-up/pull-down at power-up, individual output slew-rate control, 5 V input tolerance and drive capability supported at the device-family level.
• Package and Mounting: 329-BBGA package (supplier device package: 329-PBGA, 31×31) in a surface-mount form factor; RoHS compliant.
• Temperature and Grade: Industrial grade with operating temperature range −40 °C to 85 °C.

Typical Applications

• Industrial Control: High I/O count and industrial temperature rating make this FPGA suitable for motor control, PLC front-ends and factory automation interfaces that require reliable operation across −40 °C to 85 °C.
• Mixed-Voltage System Interfaces: Configurable I/O and mixed-voltage operation allow bridging and protocol adaptation between 2.5 V, 3.3 V and 5 V domains in embedded systems.
• Secure, In-System Programmable Logic: Nonvolatile single-chip configuration and FuseLock™ security support applications that require field-programmable updates while protecting IP.

Unique Advantages

• High I/O Density: 249 user-programmable I/Os provide extensive external connectivity for complex interface and signal routing tasks, reducing the need for external glue logic.
• Deterministic Timing: User-controllable timing resources help deliver predictable behavior for time-critical control and interface applications.
• Robust Power Handling: Wide supply voltage range (2.25 V–5.25 V) and power-up/power-down friendly behavior simplify system power sequencing and mixed-voltage board designs.
• Nonvolatile, Secure Configuration: Single-chip nonvolatile FPGA architecture with secure programming minimizes external configuration components and protects IP in the field.
• Industry-Grade Thermal Range: Industrial temperature rating (−40 °C to 85 °C) supports deployment in demanding environmental conditions.
• Compliance and Testability: Boundary-scan (IEEE 1149.1) support improves board-level testability and manufacturing diagnostics.
