A54SX32A-FGG256

The A54SX32A-FGG256 is a commercial-grade SX-A family FPGA from Microchip Technology supplied in a 256-ball fine-pitch BGA (17 × 17) package. It delivers a nonvolatile, single-chip FPGA solution with 48,000 system gates (approximately), 2,880 logic elements, and 203 user I/Os—designed for embedded applications that require flexible I/O, secure programming, and deterministic timing.

With support for mixed 2.5 V, 3.3 V and 5 V I/O standards, a wide supply range (2.25 V to 5.25 V), and RoHS-compliant packaging, this device targets designers who need a compact, configurable logic device with on-chip security and in-system diagnostic capabilities.

Key Features

• Core Capacity — Approximately 48,000 system gates and 2,880 logic elements provide mid-range logic density for a range of embedded designs.
• I/O Flexibility — 203 user I/Os with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, plus 5 V input tolerance and 5 V drive strength options.
• Performance — Datasheet-stated performance capability includes up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• Nonvolatile Single-Chip Architecture — Device stores configuration on-chip, eliminating the need for external configuration memory.
• Power and I/O Robustness — Hot-swap compliant I/Os and power-up/power-down friendly behavior (no sequencing required for supply voltages) simplify system integration.
• Security and Test — Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering and IEEE 1149.1 (JTAG) boundary-scan testing support.
• Deterministic Timing & Diagnostics — User-controllable timing and in-system diagnostic/verification capability with Silicon Explorer II.
• Package & Mounting — 256-ball fine-pitch FBGA (256-FPBGA, 17 × 17) in a surface-mount format for dense board layouts.
• Power Supply & Temperature — Operating supply range of 2.25 V to 5.25 V; commercial temperature grade rated 0 °C to 70 °C.
• Embedded Memory — No on-chip RAM (Total Ram Bits: 0), enabling predictable, register- and logic-focused designs.
• Regulatory — RoHS-compliant packaging.

Typical Applications

• PCI-based Systems — 66 MHz PCI compliance and configurable 3.3 V/5 V PCI I/O support make the device suitable for legacy and PCI add-on functions.
• Secure or IP-Protected Designs — FuseLock™ secure programming supports designs where protection of bitstreams and IP is required.
• In-System Diagnostics and Verification — Built-in JTAG boundary-scan and Silicon Explorer II support simplify board-level testing and in-field diagnostics.
• Mixed-Voltage Embedded Designs — Configurable I/O voltage support and wide supply range allow interface with 2.5 V, 3.3 V and 5 V peripherals in compact PCB implementations.

Unique Advantages

• Balanced Logic Density: 2,880 logic elements and ~48,000 system gates provide a mid-range capacity for control, glue logic, and protocol handling without excessive board area.
• High I/O Count in a Compact Package: 203 user I/Os in a 256-FPBGA (17 × 17) package enable dense routing and multiple peripheral interfaces in a small footprint.
• On-Chip Nonvolatile Configuration: Single-chip, nonvolatile architecture removes the need for external configuration memory and streamlines system start-up.
• Flexible Voltage and I/O Standards: Support for 2.5 V, 3.3 V and 5 V signaling with 5 V tolerance and drive options helps integrate with a broad set of legacy and modern devices.
• Security and Testability: Integrated FuseLock programming and IEEE 1149.1 boundary-scan improve IP protection and enable standardized board-level testing.
• Design Predictability: Deterministic, user-controllable timing and diagnostic tools assist in timing closure and reduce validation time.
