A54SX32-1BGG329I

The A54SX32-1BGG329I is an SX-A family FPGA offered by Microchip Technology. It provides a nonvolatile, single-chip programmable fabric with 48,000 system gates and 2,880 logic elements, and supports up to 249 user I/O pins in a 329-pin BGA package.

Designed for industrial applications, the device supports a 3.0 V to 5.5 V supply range and a –40 °C to 85 °C operating range. SX-A family characteristics include high-performance internal and system timing (family-level ratings up to 350 MHz internal and 250 MHz system performance) and industry features such as hot-swap-compliant I/Os and 66 MHz PCI support.

Key Features

• Core Resources 48,000 system gates and 2,880 logic elements provide the programmable logic capacity for glue logic, protocol bridging, and custom control functions.
• I/O and Interface Flexibility Up to 249 user I/Os with configurable I/O support for 5 V TTL, 3.3 V LVTTL, 2.5 V LVCMOS2 and 5 V-tolerant inputs and drive strengths; hot-swap compliant I/Os and 66 MHz PCI compatibility at the family level.
• Nonvolatile Single-Chip Configuration Nonvolatile, single-chip architecture eliminates external configuration memory and supports Actel Secure Programming technology (FuseLock™) for protection against reverse engineering.
• Power and I/O Control Power-up/power-down friendly operation with no sequencing required for supply voltages, configurable weak pull-up or pull-down at power-up, and individual output slew-rate control.
• Performance and Timing SX-A family-level performance ratings include up to 250 MHz system performance and up to 350 MHz internal performance; deterministic, user-controllable timing supports predictable timing closure.
• Package and Environmental 329-ball PBGA (31 × 31) package, industrial temperature grade (–40 °C to 85 °C), and RoHS-compliant packaging.
• Test and Diagnostics Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability using Silicon Explorer II (series-level tool support).

Typical Applications

• PCI-based Interfaces Use in board-level designs that require 66 MHz PCI compatibility and flexible I/O voltage support for mixed-voltage interconnects.
• Industrial Control and Embedded Systems Industrial temperature rating and wide supply range make the device suitable for factory automation, motion control, and embedded control modules.
• High-Density I/O and Protocol Bridging The 249 user I/Os enable complex interface aggregation, protocol translation, and I/O expansion on controller or adapter boards.
• Secure and Configurable Logic Nonvolatile configuration and FuseLock™ security support applications where in-field programming and IP protection are required.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates the need for external configuration memory and simplifies board-level BOM and startup sequencing.
• High I/O count in a compact package: 249 I/Os in a 329-ball PBGA (31 × 31) enable dense interface integration without large form-factor packages.
• Mixed-voltage I/O support and 5 V tolerance: Flexible interface options reduce level-shifter requirements when connecting to legacy 5 V logic and modern 3.3 V/2.5 V devices.
• Industrial temperature rating: Rated for –40 °C to 85 °C operation to meet common industrial environmental requirements.
• Security and testability: FuseLock™ programming protection and IEEE 1149.1 boundary-scan support streamline production test and help protect IP.
• Speed-grade optimization: The –1 speed grade delivers approximately 15% higher performance than the standard grade (series-level speed grade definition).
