A54SX08A-2TQG100

The A54SX08A-2TQG100 is a nonvolatile SX-A family field programmable gate array from Microchip Technology. It provides 12,000 system gates implemented as approximately 768 logic elements with up to 81 user-programmable I/O pins in a 100-pin thin quad flat pack (100-LQFP) surface-mount package.

Designed for commercial-temperature embedded designs, this device targets applications that require configurable I/O, deterministic timing, and single-chip nonvolatile FPGA functionality with flexible mixed-voltage I/O support and on-chip security options.

Key Features

• Core Capacity — 12,000 system gates implemented as approximately 768 logic elements and up to the device maximum of dedicated flip-flops as reported in the SX-A family tables.
• Performance — SX-A family performance characteristics listed in the product datasheet include up to 250 MHz system performance and up to 350 MHz internal performance.
• User I/O — 81 user-programmable I/O pins (package-dependent routing) with configurable I/O support for multiple signaling standards and mixed-voltage operation.
• Configurable I/O Voltage — Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V operation and configurable I/O options listed for PCI, TTL, LVTTL and LVCMOS2 signaling in the SX-A family documentation.
• Supply and Power — Wide supply input range from 2.25 V to 5.25 V and power-up/down friendly behavior noted for the SX-A family (no special sequencing required for supply voltages).
• Nonvolatile Single-Chip Solution — On-chip, nonvolatile configuration memory as part of the SX-A family architecture (single-chip configuration).
• System and Design Features — Hot-swap compliant I/Os, 66 MHz PCI compliance noted for the family, deterministic user-controllable timing, and boundary-scan (JTAG) testing capability.
• Security and Diagnostics — Family-level secure programming technology with FuseLock™ and in-system diagnostic and verification capability with Silicon Explorer II (as documented for SX-A devices).
• Package & Mounting — 100-pin thin quad flat pack (100-LQFP / supplier package 100-TQFP 14×14); surface mount.
• Commercial Temperature Grade — Operating temperature range 0 °C to 70 °C; RoHS compliant.

Typical Applications

• Embedded control logic — Implement custom glue logic, state machines, and control functions using the device’s 12,000 system gates and 768 logic elements.
• Interface bridging and I/O expansion — Use the 81 configurable I/Os and mixed-voltage support to interface between different logic levels and peripheral buses.
• PCI and peripheral interfacing — SX-A family PCI compliance and configurable I/O make the device suitable for designs that incorporate 66 MHz PCI signaling and related peripheral logic.
• In-system verification and secure configurations — Leverage the family’s in-system diagnostic features and FuseLock programming to protect and validate designs in the field.

Unique Advantages

• Nonvolatile single-chip FPGA: Eliminates the need for external configuration memory, simplifying board design and power sequencing.
• Flexible mixed-voltage I/O: Supports 2.5 V, 3.3 V and 5 V operation with configurable I/O standards to ease integration with varied legacy and modern interfaces.
• Deterministic timing control: Family-level features provide user-controllable, deterministic timing useful for time-critical logic and interface implementations.
• On-chip security and diagnostics: Secure programming (FuseLock™) and Silicon Explorer II diagnostics help protect IP and verify operation during development and deployment.
• Compact surface-mount packaging: 100-pin TQFP/LQFP package provides a balance of I/O count and PCB footprint for space-constrained commercial designs.
• RoHS compliant: Conforms to RoHS requirements for environmental compliance in commercial products.
