A54SX16A-1TQG100

The A54SX16A-1TQG100 is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It provides user-configurable logic and I/O resources in a commercial-grade device optimized for reprogrammable logic functions in 0 °C to 70 °C environments.

With 24,000 system gates and 1,452 logic elements, the device targets commercial applications that require configurable I/O, deterministic timing, and in-system diagnostic capability, while supporting mixed-voltage operation across a broad supply range.

Key Features

• Core Capacity — Approximately 24,000 system gates and 1,452 logic elements provide substantial on-chip combinatorial and sequential resources for custom logic implementations.
• Performance — Series-level performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Configurable I/O and Mixed-Voltage Support — Configurable I/O supports 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2; devices support 2.5 V, 3.3 V, and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Voltage and Power — Operates from a wide supply range of 2.25 V to 5.25 V and is power-up/power-down friendly with no required sequencing for supply voltages.
• I/O Robustness — Hot-swap compliant I/Os and configurable weak pull-up/pull-down options at power-up improve board-level integration and reliability.
• Package and Mounting — Available in a 100-pin LQFP package (supplier device package: 100-TQFP, 14×14) and designed for surface-mount assembly.
• Security and Test — Actel Secure Programming Technology with FuseLock™ helps prevent reverse engineering and design theft; boundary-scan testing compliant with IEEE 1149.1 (JTAG) is supported.
• Deterministic Timing and Signal Control — User-controllable timing with individual output slew rate control and support for up to 100% resource utilization and pin locking.
• Diagnostics — In-system diagnostic and verification capability with Silicon Explorer II enables targeted verification and troubleshooting.
• Compliance — RoHS compliant.

Typical Applications

• PCI interface and bridging — 66 MHz PCI compliance and configurable I/O make the device suitable for implementing PCI peripheral logic and interface bridging in commercial systems.
• Mixed-voltage interface control — Support for 2.5 V, 3.3 V, and 5 V I/O standards enables level translation and mixed-voltage peripheral interfacing on a single device.
• Embedded control and custom logic — The combination of 24,000 system gates and 1,452 logic elements is well suited for implementing custom state machines, control logic, and glue logic in commercial products.
• Manufacturing test and diagnostics — Boundary-scan (IEEE 1149.1) support and in-system diagnostic tools simplify board-level test and debug activities.
