A54SX16A-TQ144I

The A54SX16A-TQ144I is a Field Programmable Gate Array (FPGA) from Microchip Technology's SX-A family, supplied in a 144-pin LQFP/TQFP package. This industrial-temperature device provides 24,000 system gates and 1,452 logic elements, and is optimized for applications that require a nonvolatile, single-chip FPGA with configurable I/O and deterministic timing.

As a member of the SX-A family, the device benefits from family-level characteristics such as nonvolatile on-chip configuration, configurable mixed-voltage I/O support, boundary-scan (JTAG) testing, and secure programming technology.

Key Features

• Logic Capacity — 24,000 system gates and 1,452 logic elements provide a compact logic fabric for glue logic, control functions, and medium-complexity programmable logic tasks.
• User I/O — 113 user-programmable I/O pins in the 144-pin package enable flexible external interfacing and signal routing.
• Package and Mounting — Supplied in a 144-pin LQFP package (supplier device package: 144-TQFP, 20×20) with surface-mount mounting for standard PCB assembly.
• Voltage Flexibility — Supports a 2.25 V to 5.25 V supply range and family-level configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2, enabling mixed-voltage interfacing.
• Industrial Temperature Grade — Rated for operation from −40 °C to +85 °C for industrial applications.
• Nonvolatile Single-Chip Solution — SX-A family nonvolatile configuration provides single-chip programmability without the need for external configuration memory.
• Performance (Family) — SX-A family devices offer up to 250 MHz system performance and up to 350 MHz internal performance, enabling high-speed internal logic and system clocking where required.
• System and Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and family-level features such as hot-swap compliant I/Os, power-up/down friendly operation, and configurable pull-up/pull-down on I/Os.
• Security and Reliability — Family-level Actel Secure Programming Technology with FuseLock™ helps protect design IP and prevent reverse engineering.

Typical Applications

• Industrial Control — Implement real-time control logic, interface translation, and system glue in equipment that requires industrial-temperature operation.
• Interface Bridging — Use the device’s configurable mixed-voltage I/O and abundant user I/Os for protocol conversion and legacy bus bridging, including PCI-capable signals at family level.
• Embedded System Logic — Integrate custom state machines, peripheral controllers, and deterministic timing logic within embedded products that benefit from a nonvolatile FPGA.

Unique Advantages

• Highly integrated logic capacity: 24,000 system gates and 1,452 logic elements reduce external glue logic and simplify PCB designs.
• Nonvolatile configuration: Single-chip, nonvolatile architecture removes the need for external configuration memory and simplifies system initialization.
• Flexible I/O interfacing: Broad supply range (2.25–5.25 V) and family-level configurable I/O options enable mixed-voltage designs and simplify board-level integration.
• Industrial robustness: Rated for −40 °C to +85 °C operation for deployment in industrial environments.
• Built-in security and testability: FuseLock secure programming and IEEE 1149.1 boundary-scan support enhance IP protection and production testing capabilities.
• Deterministic timing control: Family-level deterministic, user-controllable timing supports predictable behavior for timing-sensitive designs.
