A54SX32A-BG329

The A54SX32A-BG329 is a commercial-grade FPGA from Microchip Technology's SX‑A family, delivered as a nonvolatile, single‑chip programmable logic device. It provides 48,000 system gates implemented across 2,880 logic elements with up to 249 user I/O pins in a 329‑ball BGA package.

Designed for commercial embedded applications that require flexible mixed‑voltage I/O and deterministic timing, the device combines high internal performance (up to 350 MHz) and robust system performance (up to 250 MHz) with features such as hot‑swap compliant I/Os, JTAG boundary‑scan, and on‑chip security mechanisms.

Key Features

• Core Capacity: 48,000 system gates realized across 2,880 logic elements, suitable for medium-complexity programmable logic and control functions.
• I/O and Voltage Flexibility: Up to 249 user‑programmable I/O pins with configurable support for multiple voltage standards; device supplies operate from 2.25 V to 5.25 V and support mixed‑voltage operation.
• Performance: Series-level performance targets include up to 250 MHz system performance and up to 350 MHz internal performance for timing‑sensitive logic paths.
• Power-Up and Hot-Swap Friendly: I/O design supports hot‑swap operation and power‑up/down behavior that does not require strict supply sequencing.
• Standards and Test: 66 MHz PCI compliance and IEEE 1149.1 (JTAG) boundary‑scan testing are supported for in‑system testability and legacy bus interfacing.
• Security and Diagnostics: Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering and in‑system diagnostic/verification capability with Silicon Explorer II.
• Package and Mounting: 329‑ball BGA package (product package case: 329‑BBGA; supplier device package listed as 329‑PBGA 31×31) and surface‑mount mounting type.
• Commercial Temperature Grade: Rated for 0 °C to 70 °C operating temperature and RoHS‑compliant packaging.
• Memory: No on‑chip RAM (Total RAM bits: 0), enabling designs that rely on external memory or are optimized for combinational and flip‑flop based logic.

Typical Applications

• Interface Bridging and Glue Logic: Use the A54SX32A-BG329 for board‑level protocol translation and glue logic where mixed‑voltage I/O and configurable pin behavior are required.
• PCI and Peripheral Interfaces: Leverage the device's 66 MHz PCI compliance and 5 V tolerant I/Os for interfacing with PCI‑based subsystems and legacy peripherals.
• Embedded Control and State Machines: Implement control logic, sequencers, and finite state machines using the 2,880 logic elements and dedicated flip‑flop resources.
• In‑System Test and Diagnostics: Integrate boundary‑scan (IEEE 1149.1) and Silicon Explorer II diagnostics for manufacturing test and in‑system verification.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates external configuration memory and simplifies system boot and configuration management.
• Mixed‑Voltage I/O Flexibility: Supports 2.5 V, 3.3 V, and 5 V operation with 5 V input tolerance and configurable I/O standards, reducing the need for level‑shifters on mixed‑voltage boards.
• Deterministic Timing: User‑controllable timing characteristics help designers achieve predictable timing closure for critical interfaces.
• Security‑Oriented Programming: FuseLock™ technology provides a hardware mechanism to protect designs against reverse engineering and unauthorized access.
• Testability and Diagnostics: Boundary‑scan support plus in‑system diagnostic capability streamline board bring‑up and field troubleshooting.
• Compact, Surface‑Mount BGA Package: 329‑ball BGA footprint enables high I/O density in a compact form factor for board‑space constrained designs.
