A54SX08A-1TQ144

The A54SX08A-1TQ144 is a commercial-grade SX-A family FPGA from Microchip Technology, delivered in a 144-pin thin/LQFP package. It provides a nonvolatile, single-chip FPGA solution with 12,000 system gates and 768 logic elements suited for designs that require flexible I/O, configurable timing, and on-chip nonvolatile configuration.

Targeted at system designs requiring mixed-voltage I/O and PCI-capable interfaces, this device combines dedicated flip-flop resources, 113 user I/Os, and a wide supply range to support a variety of embedded applications within a 0 °C to 70 °C operating window.

Key Features

• Core Capacity  12,000 system gates and 768 logic elements (logic modules) for implementing mid-density logic and control functions.
• Flip-Flop Resources  Up to 2,012 dedicated flip-flops available in the SX-A family architecture for register-heavy designs.
• I/O and Mixed-Voltage Support  113 user I/Os in the 144-pin package; configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 with 5 V input tolerance and 5 V drive strength options documented by the family.
• Performance  Family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance as specified for the SX-A family.
• Nonvolatile Single-Chip Configuration  Nonvolatile architecture removes the need for external configuration memory and supports Power-Up/Down friendly operation without supply sequencing.
• Supply and Operating Range  Voltage supply range of 2.25 V to 5.25 V and commercial temperature grading of 0 °C to 70 °C.
• System and Testability  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and family support for in-system diagnostics and verification with Silicon Explorer II.
• Package and Mounting  Surface-mount 144-pin package (144-LQFP / supplier device package 144-TQFP, 20×20 mm) for compact board layouts.
• Low-Level I/O Controls  Configurable weak pull-up/pull-down at power-up and individual output slew rate control options are available at the family level.
• Security  Actel Secure Programming Technology with FuseLock™ for design protection and prevention of reverse engineering (family feature).
• On-Chip Memory  No embedded RAM bits (Total Ram Bits: 0) as specified for this device.

Typical Applications

• PCI Interface Logic  Use where 66 MHz PCI compliance and configurable I/O voltage support are required to implement PCI endpoints or bridges.
• Mixed-Voltage System Glue  Ideal for interfacing between 5 V and lower-voltage domains thanks to configurable I/O standards and 5 V input tolerance.
• Embedded Control and Timing  Nonvolatile single-chip FPGA with deterministic, user-controllable timing and a significant flip-flop resource set for control, sequencing, and timing-critical logic.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates external configuration memory and simplifies power sequencing for more robust system startup.
• Flexible I/O voltage options: Built-in support for multiple I/O standards (3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, 2.5 V LVCMOS2) and 5 V input tolerance enable broad board-level interfacing without additional level shifters.
• Configurable timing and deterministic behavior: Family-level deterministic, user-controllable timing gives designers tighter control over timing closure and system behavior.
• Design protection features: FuseLock™ secure programming technology provides a hardware-level option to prevent reverse engineering of the programmed design.
• Compact package with ample I/O: 144-pin LQFP/TQFP packaging delivers 113 user I/Os for mid-density designs in space-constrained applications.
• Test and debug support: Boundary-scan (IEEE 1149.1) and in-system diagnostics with Silicon Explorer II help streamline bring-up and manufacturing test.
