A54SX32A-2BGG329I

The A54SX32A-2BGG329I is an SX‑A family FPGA from Microchip Technology offering a nonvolatile, single‑chip reconfigurable logic solution in a 329‑ball BGA package. It delivers approximately 48,000 system gates and 2,880 logic elements with a high I/O count (249 pins), making it suitable for industrial embedded designs that require deterministic timing, high I/O density and in‑system programmability.

Key attributes include multi‑voltage I/O support, wide supply range, industrial temperature grading, and features for in‑system verification and security as documented in the SX‑A family datasheet.

Key Features

• Logic Capacity Approximately 48,000 system gates and 2,880 logic elements provide reconfigurable logic resources for moderate‑complexity designs.
• I/O Density 249 user‑programmable I/O pins enable designs that require extensive external interfacing and signal routing.
• Nonvolatile Single‑Chip Configuration Device stores configuration on‑chip, removing the need for external configuration memory and supporting immediate system operation after power‑up.
• Voltage and I/O Flexibility Supply range 2.25 V to 5.25 V with configurable I/O support and 5 V input tolerance as described in the SX‑A family documentation.
• Performance SX‑A family performance metrics include up to 250 MHz system performance and up to 350 MHz internal performance (family characteristics per datasheet).
• System Reliability & Test Boundary‑scan testing compliant with IEEE 1149.1 (JTAG) and in‑system diagnostic/verification capabilities are provided by the SX‑A family toolset.
• Security Actel Secure Programming Technology with FuseLock™ is included in the SX‑A family to protect design IP (family feature).
• Package & Mounting 329‑ball PBGA (329‑PBGA, 31×31) package, surface mount mounting type suitable for compact board designs.
• Industrial Grade Temperature grade: Industrial with operating range −40 °C to 85 °C.
• RoHS Compliant Device is RoHS compliant.
• On‑Chip Memory No embedded RAM bits (Total RAM Bits: 0), which is relevant when planning external memory for designs that require storage.

Typical Applications

• Industrial Control Reconfigurable control logic and I/O aggregation for factory automation and motion control systems that require operation across an industrial temperature range.
• Embedded Systems Custom peripheral interfacing and glue logic in compact, single‑board embedded systems leveraging high I/O count and nonvolatile configuration.
• In‑System Verification & Diagnostics Designs that require in‑system diagnostic capability and boundary‑scan testability during production test and field maintenance.

Unique Advantages

• Nonvolatile, single‑chip solution: Eliminates external configuration memory, simplifying BOM and system boot sequence.
• High I/O count: 249 user I/Os support dense external interfacing without the need for external I/O expanders.
• Multi‑voltage I/O and wide supply range: 2.25 V to 5.25 V supply range and configurable I/O levels provide flexibility for mixed‑voltage system designs.
• Industrial temperature rating: Qualified for −40 °C to 85 °C operation to meet typical industrial environment requirements.
• Security and testability: FuseLock™ secure programming and IEEE 1149.1 boundary‑scan support help protect IP and simplify production test flows.
• Documented family performance: SX‑A family datasheet documents system and internal performance figures and design guidance to accelerate integration.
