A54SX32-2BG329

The A54SX32-2BG329 is an SX-A family FPGA from Microchip Technology, configured as a nonvolatile, single-chip programmable logic device. It provides 48,000 system gates and approximately 2,880 logic elements with up to 249 user I/Os in a 329-ball BGA package.

Designed for commercial-temperature embedded systems, this device supports mixed-voltage I/O, hot-swap friendliness, and toolbox features for in-system diagnostics and boundary-scan testing—making it suitable for board-level programmable logic, interface bridging, and control functions where nonvolatile configuration and high I/O count are required.

Key Features

• Core Capacity — 48,000 system gates and 2,880 logic elements provide substantial combinatorial and registered logic resources for medium-complexity designs.
• I/O and Interface Flexibility — Up to 249 user I/Os with configurable I/O support for 5 V TTL/PCI, 3.3 V LVTTL, and 2.5 V LVCMOS; supports mixed-voltage operation and 5 V input tolerance/drive.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family-level specification).
• Nonvolatile Single-Chip Solution — Device retains configuration without external memory, simplifying system design and reducing BOM.
• Speed Grade — The “-2” speed grade indicates approximately 25% faster performance than standard (family-level speed grade definition).
• Power and Supply — Supports a wide voltage supply range from 3.0 V to 5.25 V and is power-up/power-down friendly (no sequencing required for supply voltages, family-level feature).
• Package and Mounting — 329-ball BGA (supplier package: 329-PBGA, 31 × 31) in a surface-mount form factor for high I/O density and compact board footprint.
• System Reliability & Testability — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability available via Silicon Explorer II (family-level feature).
• Security Features — Includes Actel Secure Programming Technology with FuseLock™ to protect designs from reverse engineering (family-level feature).
• Environmental & Grade — Commercial grade operation from 0 °C to 70 °C and RoHS compliant.
• On-Chip Memory — Total RAM Bits: 0 (no embedded RAM on this device).

Typical Applications

• PCI and Bus Interface Logic — 66 MHz PCI compliance at the family level and high I/O count enable implementation of board-level interface bridging and protocol conversion functions.
• Mixed-Voltage I/O Systems — Configurable 5 V/3.3 V/2.5 V I/O and 5 V tolerance support mixed-voltage interfaces and legacy peripheral integration.
• Nonvolatile Configuration Logic — Single-chip nonvolatile architecture is suited for designs that require on-board programmable logic without external configuration memory.
• Boundary-Scan and Board Bring-Up — Built-in JTAG boundary-scan and in-system diagnostics assist manufacturing test and field debugging workflows.

Unique Advantages

• High I/O Density: 249 user I/Os in a 329-ball BGA package enables dense connectivity for complex board-level functions.
• Nonvolatile, Single-Chip Deployment: Eliminates the need for external configuration memory, reducing BOM and simplifying system power sequencing.
• Mixed-Voltage Flexibility: Configurable I/O standards and 5 V tolerance allow the device to interface directly with a wide range of legacy and modern signals.
• Deterministic Timing and Performance Headroom: Family-level performance specs (up to 250 MHz system / 350 MHz internal) and user-controllable timing afford predictable timing closure for critical paths.
• Built-In Security and Test: FuseLock programming and IEEE 1149.1 boundary-scan support protect IP and streamline testability during production and service.
• Commercial-Grade Reliability: Specified for 0 °C to 70 °C operation and RoHS compliant to meet standard commercial product requirements.
