A54SX32A-TQ100M

The A54SX32A-TQ100M is a military-grade SX-A family FPGA from Microchip Technology offered in a 100-pin thin LQFP surface-mount package. It provides a nonvolatile single-chip FPGA solution with a balance of logic capacity, configurable I/O and wide operating ranges for designs requiring robust, deterministic programmable logic.

Targeted at applications that require high-reliability operation and mixed-voltage interfacing, the device combines 48,000 system gates and 2,880 logic elements with a broad supply voltage range and extended temperature rating to support demanding embedded systems.

Key Features

• Logic Capacity — 48,000 system gates and approximately 2,880 logic elements provide significant programmable logic resources for mid-density designs.
• I/O and Voltage Flexibility — 81 user I/O pins with configurable I/O support and mixed-voltage operation across 2.25 V to 5.25 V, enabling direct interfacing with a range of peripheral voltage domains.
• Family Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical logic (SX-A family specification).
• Nonvolatile Single-Chip Architecture — Family-level single-chip, nonvolatile configuration removes the need for external configuration memory and supports power-up/power-down friendly operation without supply sequencing (SX-A family specification).
• Robust I/O Features — Hot-swap compliant I/Os, 5 V input tolerance, configurable weak pull-up/pull-down at power-up, and individual output slew rate control offer flexible signal integrity and board-level design options (SX-A family specification).
• Security and Test — SX-A family devices support Actel Secure Programming technology with FuseLock™ for protection against reverse engineering and include IEEE 1149.1 boundary-scan (JTAG) for interconnect testability and in-system diagnostics.
• Package and Mounting — 100-pin thin LQFP (TQFP 14×14) surface-mount package for compact board placement and standard PCB assembly flows.
• Temperature and Grade — Military-grade device with an operating temperature range of −55 °C to +125 °C for deployment in harsh and mission-critical environments.
• Compliance — RoHS compliant.

Typical Applications

• Military and Defense Electronics — Military-grade temperature rating and rugged packaging make the device suitable for mission-critical control, signal processing, and interface logic in defense systems.
• High-Reliability Embedded Control — Nonvolatile single-chip configuration and JTAG boundary-scan support robust in-system diagnostics and field maintenance for embedded controllers.
• Mixed-Voltage Interface Bridging — Configurable I/O and wide supply range enable protocol bridging and interface logic between 2.5 V, 3.3 V and 5 V domains.
• Deterministic Logic and Timing — Family-level deterministic, user-controllable timing makes the FPGA suitable for designs that require predictable latency and timing closure.

Unique Advantages

• Military-Grade Reliability: Specified for −55 °C to +125 °C operation and offered in a military grade, supporting deployment in harsh environments.
• Nonvolatile, Power-Friendly Design: Single-chip nonvolatile architecture eliminates external configuration memory and supports power-up/power-down without supply sequencing, simplifying system power management.
• Flexible Mixed-Voltage I/O: 81 configurable I/Os with 5 V tolerance and mixed-voltage operation reduce the need for level shifters and simplify board design.
• Security and Testability: FuseLock™ secure programming and IEEE 1149.1 boundary-scan enable protection of intellectual property and enhanced test coverage.
• Strong Performance Envelope: SX-A family performance ratings (up to 250 MHz system, up to 350 MHz internal) suit timing-sensitive logic implementations.
• Compact, Surface-Mount Package: 100-pin thin LQFP package provides a compact footprint for space-constrained PCBs while supporting standard surface-mount assembly.
