A54SX16-1TQG176

The A54SX16-1TQG176 is a commercial-grade SX family Field Programmable Gate Array (FPGA) supplied by Microchip Technology. It provides a nonvolatile, single-chip FPGA architecture with 24,000 system gates and approximately 1,452 logic elements, optimized for mixed-voltage I/O and in-system programmability.

With 147 user I/Os in a 176-pin surface-mount package and a wide supply range of 3 V to 5.25 V, this device targets designs that require flexible I/O interfacing, deterministic timing control, and embedded system integration at commercial temperatures (0 °C to 70 °C).

Key Features

• Core Capacity — Approximately 24,000 system gates and 1,452 logic elements provide a mid-range FPGA resource set for glue logic, control functions, and custom hardware implementation.
• Performance — SX family silicon delivers documented system and internal performance characteristics suitable for timing-sensitive designs, including high internal switching performance.
• I/O Flexibility — 147 user-programmable I/Os with configurable I/O support for multiple voltage domains and 5 V tolerant options as documented for the SX family.
• Mixed-Voltage Operation — Supports 2.5 V, 3.3 V, and 5 V mixed-voltage operation with 5 V input tolerance and drive capability as specified for the SX-A family.
• Nonvolatile Single-Chip Solution — On-chip nonvolatile configuration removes the need for external configuration memory, simplifying board-level design and system integration.
• Package & Mounting — Surface-mount 176-pin package (listed as 176-LQFP; supplier package noted as 176-TQFP, 24 × 24) for compact PCB layouts.
• Voltage & Temperature — Operates from 3 V to 5.25 V and rated for commercial temperature range of 0 °C to 70 °C.
• Design Security & Test — SX family includes features for boundary-scan (JTAG) and secure programming methods to protect designs and support production testability.
• RoHS Compliant — Device is listed as RoHS compliant for lead-free manufacturing environments.

Typical Applications

• Mixed-Voltage Interface Logic — Implement level translation, interface bridging, and custom I/O conditioning where 2.5 V, 3.3 V and 5 V domains must coexist.
• PCI and Legacy Bus Support — Suitable for control and glue logic in systems that require PCI-compatible I/O signaling and bus interfacing as described for the SX family.
• In-System Programmable Control — Use for in-circuit programmable state machines, peripheral control, and board-level system glue without external configuration ROM.
• Boundary-Scan and Production Test — Integrate into designs requiring IEEE 1149.1 (JTAG) boundary-scan for manufacturing test and debug.

Unique Advantages

• Nonvolatile single-chip architecture: Eliminates external configuration memory and simplifies board design and system boot-up.
• Flexible I/O with mixed-voltage support: Reduces the need for external level shifters by supporting multiple I/O voltage domains and 5 V tolerant inputs.
• Mid-range logic capacity: Approximately 1,452 logic elements and 24,000 system gates provide the right balance of integration for control, interface, and custom logic tasks.
• Compact surface-mount packaging: 176-pin LQFP/TQFP package options support high-density PCB layouts while providing up to 147 user I/Os.
• Design security and testability: Includes boundary-scan support and secure programming technology to protect intellectual property and aid production testing.
• RoHS compliant: Facilitates adoption in lead-free manufacturing environments.
