A54SX16A-1TQG144I

The A54SX16A-1TQG144I is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It delivers deterministic, user-controllable timing and configurable I/O for mixed-voltage designs, packaged in a 144-pin thin quad flat pack (TQFP/LQFP) footprint.

Designed for industrial-grade applications, this device combines 24,000 system gates with 1,452 logic elements and up to 113 user I/Os to address control, interface and system integration tasks where in-system diagnostics, security and mixed-voltage I/O flexibility are required.

Key Features

• Core Performance – Rated for up to 250 MHz system performance and 350 MHz internal performance as defined for the SX-A family.
• Logic Capacity – 24,000 system gates with approximately 1,452 logic elements to implement medium-complexity logic and control functions.
• User I/O and Mixed-Voltage Support – 113 user-programmable I/Os with configurable support for 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS operation; devices support mixed-voltage operation and 5 V input tolerance/drive strength.
• Package and Mounting – 144-pin TQFP/LQFP package (surface mount) for standard board-level integration in industrial assemblies.
• Power and Supply – Flexible supply range from 2.25 V to 5.25 V, and power-up/down friendly behavior that does not require supply sequencing.
• Industrial Temperature Grade – Operating temperature range of −40 °C to 85 °C suitable for industrial environments.
• In-System Diagnostics and Test – Supports boundary-scan testing in compliance with IEEE 1149.1 (JTAG) and includes unique in-system diagnostic and verification capability with Silicon Explorer II.
• Security and Design Protection – Includes Actel Secure Programming Technology with FuseLock™ to help protect designs against reverse engineering.
• I/O Reliability Features – Hot-swap compliant I/Os, configurable weak pull-up/pull-down at power-up, and individual output slew-rate control for signal integrity and board-level robustness.
• Deterministic Timing and Resource Utilization – Offers deterministic, user-controllable timing, up to 100% resource utilization and 100% pin locking for predictable, tight-tolerance designs.

Typical Applications

• Industrial Control – Implement custom control logic, protocol bridging or interface conditioning in industrial systems, leveraging the industrial temperature rating and mixed-voltage I/O support.
• PCI and Legacy Interface Peripherals – Suitable for 66 MHz PCI-compliant peripheral functions and I/O interfacing where 3.3 V and 5 V signal compatibility is required.
• In-System Test and Production Diagnostics – Use boundary-scan and the Silicon Explorer II capability for board-level testing, fault isolation and production verification.
• Secure, Nonvolatile Logic Functions – Deploy nonvolatile, single-chip FPGA logic with built-in programming protection for designs requiring embedded intellectual property protection.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates the need for external configuration memory by providing a nonvolatile FPGA architecture for simpler board designs.
• Mixed-Voltage Flexibility: Broad supply range (2.25 V–5.25 V) and configurable I/O levels allow easy interfacing with 5 V and 3.3 V domains without external level-shifters.
• Production-Test Ready: IEEE 1149.1 boundary-scan support and in-system diagnostics streamline manufacturing test and field debug activities.
• Design Protection: FuseLock™ secure programming technology helps protect implemented designs from unauthorized readback and reverse engineering.
• Industrial Reliability: Specified for −40 °C to 85 °C operation and surface-mount 144-LQFP packaging, enabling deployment in industrial environments.
