A54SX16P-1PQG208I

The A54SX16P-1PQG208I is a nonvolatile SX-family FPGA from Microchip Technology offered in a 208-pin BFQFP package. It delivers 24,000 system gates organized as approximately 1,452 logic elements with 175 user-programmable I/O pins, making it suitable for dense I/O and control tasks that require single-chip, nonvolatile logic integration.

Designed for industrial operation, the device supports a 3 V to 5.5 V supply range, operates from –40 °C to 85 °C, and ships in a 208-pin surface-mount package form factor. Series-level performance characteristics include system and internal clocking capability suitable for demanding embedded and interface-focused designs.

Key Features

• Core Logic  Approximately 1,452 logic elements and 24,000 system gates provide a fixed-resource fabric for implementing control, glue logic, and moderate-density datapaths.
• I/O Capacity & Flexibility  175 user I/Os with configurable support for multiple signaling types allow direct interfacing across legacy and modern voltage domains.
• Voltage & Power  Wide supply range (3 V to 5.5 V) with mixed-voltage I/O support and 5 V input tolerance to simplify integration with 3.3 V and 5 V systems.
• Performance  Series-level system performance targets (up to 250 MHz system, up to 350 MHz internal performance as specified for the SX-A family) enable high-speed control and timing-critical functions.
• Nonvolatile Single-Chip Solution  On-chip nonvolatile configuration removes the need for external configuration memory and supports immediate configuration at power-up.
• Power-Up/Down Friendly I/Os  I/O design minimizes sequencing constraints during power transitions for simpler board-level power management.
• System Reliability & Test  Boundary-scan (IEEE 1149.1/JTAG) support and in-system diagnostic capability enhance board-level test and verification options.
• Security  Series-level secure programming technology (FuseLock) helps protect design IP during programming and in-system operation.
• Package & Mounting  208-pin BFQFP surface-mount package (supplier device package: 208-PQFP, 28×28) for high-density PCB layouts.
• Environmental  RoHS compliant and specified for industrial temperature operation (–40 °C to 85 °C).
• Embedded Memory  No on-chip RAM (Total RAM Bits: 0), useful information for memory partitioning and external memory planning.

Typical Applications

• Industrial control and automation  Implement control logic, I/O aggregation, and real-time glue logic in systems that require industrial temperature operation.
• Legacy system interface and PCI-capable boards  Configurable I/Os with support for 3.3 V and 5 V signaling and PCI-related voltage levels simplify integration with older buses and mixed-voltage PCBs.
• Instrumentation and test equipment  Deterministic timing and boundary-scan support aid precision control and onboard testability in laboratory and manufacturing equipment.
• Embedded system glue logic  Use as a single-chip programmable replacement for discrete TTL/ASIC glue logic to consolidate BOM and simplify board design.

Unique Advantages

• Nonvolatile single-chip FPGA: Eliminates the need for external configuration memory and simplifies system boot-up and supply sequencing.
• Wide I/O voltage support: Configurable I/O and 5 V input tolerance enable direct interfacing with both 3.3 V and legacy 5 V logic without level-shifter hardware.
• Industrial temperature rating: Specified operation from –40 °C to 85 °C for reliable deployment in industrial environments.
• High I/O count: 175 user I/Os allow extensive peripheral and bus connectivity from a single device.
• Security and test features: Built-in secure programming technology and JTAG boundary-scan support protect IP and improve production test coverage.
• RoHS compliant: Environmentally compliant packaging reduces supply-chain complexity for lead-free manufacturing.
