A54SX32A-CQ84

The A54SX32A-CQ84 is a commercial-grade SX-A family field programmable gate array from Microchip Technology designed for surface-mount applications. It delivers a mid-range logic capacity and flexible I/O options in an 84-pin ceramic quad flat pack (CQFP) with exposed pad and tie bar.

Targeted at commercial embedded designs that require configurable logic, mixed-voltage interfacing and compact packaging, the device combines 48,000 system gates and 2,880 logic elements with broad supply voltage support to simplify integration across 2.25 V–5.25 V systems.

Key Features

• Core Capacity — Approximately 48,000 system gates implemented across 2,880 logic elements, providing a balance of logic resources for mid-density designs.
• I/O Count — 69 total I/O pins to support a variety of peripheral interfaces and board-level connectivity requirements.
• No Embedded RAM — Total on-chip RAM bits: 0, suitable for control and glue-logic applications where dedicated external memory is used.
• Package — 84-pin CQFP with exposed pad and tie bar (supplier package: 84-CQFP, 42×42 mm), designed for surface-mount assembly.
• Voltage Range — Flexible supply range from 2.25 V to 5.25 V to accommodate mixed-voltage designs and legacy 5 V interfaces.
• Operating Temperature — Commercial operating range from 0 °C to 70 °C for standard commercial applications.
• Performance — SX-A family timing includes low pin-to-pin clock-to-out values (example: 5.3 ns for A54SX32A in family documentation), enabling responsive logic paths in timing-sensitive applications.
• Power & I/O Behavior — Family-level features include hot-swap–compliant I/Os and power-up/power-down friendliness (no sequencing required for supply voltages), supporting robust board-level power behavior.
• Security & Test — SX-A family capabilities include secure programming technology and IEEE 1149.1 (JTAG) boundary-scan support, enabling design protection and standard test access.
• Compliance — RoHS compliant material status.

Typical Applications

• Commercial Embedded Systems — Implement glue logic, control sequencing and protocol translation where moderate gate density and configurable I/O are required.
• Interface Bridge and Level Translation — Mixed-voltage operation across 2.25 V–5.25 V supports bridging between modern low-voltage logic and legacy 5 V peripherals.
• Board-Level Control and Sequencing — Use the FPGA to centralize board control functions such as reset sequencing, state machines, and peripheral arbitration.
• Prototyping and Low-to-Mid Density Implementations — Compact CQFP packaging and 2,880 logic elements make the device suitable for constrained PCBs and prototype builds requiring reprogrammable logic.

Unique Advantages

• Balanced Logic Capacity: 48,000 system gates and 2,880 logic elements provide sufficient resources for mid-range designs without moving to larger, more costly devices.
• Flexible Voltage Support: 2.25 V–5.25 V supply range enables straightforward integration with a broad set of I/O standards and legacy 5 V systems.
• Compact, Surface-Mount Package: 84-pin CQFP with exposed pad optimizes PCB footprint while providing thermal conduction and mechanical stability.
• Deterministic Timing: Family-level low clock-to-out characteristics support predictable timing closure for control and interface logic.
• Design Protection & Testability: Secure programming technology and JTAG boundary-scan support improve IP protection and manufacturing test access.
• RoHS Compliance: Meets material compliance requirements for modern commercial designs.
