A54SX08-1FG144

The A54SX08-1FG144 is an SX-A family Field Programmable Gate Array from Microchip Technology supplied in a 144-ball fine-pitch BGA / 144-LBGA surface-mount package. It provides a nonvolatile, single-chip FPGA solution with approximately 12,000 system gates and 768 logic elements, and is targeted at designs that require reconfigurable logic, mixed-voltage I/O support and in-system diagnostic capability.

Designed for commercial-temperature applications (0 °C to 70 °C), the device supports mixed 2.5 V, 3.3 V and 5 V I/O schemes and a supply range of 3 V to 5.25 V, enabling flexible interfacing in a variety of embedded and PCI-capable systems.

Key Features

• Core capacity — Approximately 12,000 system gates and 768 logic elements provide on-chip programmable logic for glue logic, protocol bridging and control functions.
• Performance — SX-A family characteristics include up to 250 MHz system performance and up to 350 MHz internal performance; the –1 speed grade is approximately 15% faster than standard.
• I/O flexibility — 111 user I/Os with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; 5 V input tolerance and 5 V drive strength enable mixed-voltage designs and direct interfacing to a wide range of peripherals.
• Nonvolatile single-chip solution — Device stores configuration on-chip, eliminating the need for external configuration memory and simplifying board design.
• System and test features — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and unique in-system diagnostic and verification capability using Silicon Explorer II (family feature).
• Security — Actel Secure Programming Technology with FuseLock™ to protect design IP from reverse engineering (family feature).
• Package and mounting — 144-ball fine-pitch BGA / 144-LBGA surface-mount package (supplier device package: 144-FPBGA 13×13), compact footprint for space-constrained boards.
• Power and environmental — Operating supply range 3 V to 5.25 V; commercial temperature grade 0 °C to 70 °C; RoHS compliant.

Typical Applications

• PCI and peripheral interfaces — Use the device’s PCI-compliant I/O and 66 MHz PCI support to implement interface logic and protocol handling for add-on cards and peripheral modules.
• Mixed-voltage system glue logic — Flexible I/O voltage support and 5 V tolerance make the FPGA suitable for bridging between logic domains and integrating legacy 5 V signals with modern 3.3 V or 2.5 V subsystems.
• Embedded control and custom logic — With ~12,000 system gates and 768 logic elements, implement control state machines, custom datapaths and peripheral controllers in a single-chip solution.
• In-system verification and diagnostics — Leverage the family’s Silicon Explorer II capability and JTAG boundary-scan for on-board verification and fault isolation during development and production testing.

Unique Advantages

• Highly integrated, nonvolatile FPGA: On-chip configuration removes the need for external configuration memory, reducing BOM and simplifying power-up sequencing.
• Flexible mixed-voltage I/O: Configurable I/O standards and 5 V tolerance allow direct interfacing to different logic families without level-shifters in many cases.
• Compact, production-ready package: 144-ball fine-pitch BGA / 144-LBGA in a surface-mount format saves board area while delivering 111 user I/Os.
• Deterministic timing and diagnostics: Family-level support for deterministic, user-controllable timing plus in-system diagnostic tools aids timing closure and debug.
• Security features: FuseLock programming technology helps protect intellectual property and prevent reverse engineering.
• RoHS-compliant commercial solution: Designed for commercial-temperature systems with RoHS-compliant packaging for regulatory compliance.
