A54SX32A-FG256A

Overview

The A54SX32A-FG256A is an automotive-grade Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 48,000 system gates and supports up to 203 user-programmable I/O pins. The device operates on a 0.22µ CMOS process technology and delivers internal performance of 250 MHz. It is housed in a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The component supports power supply voltages ranging from 2.25 V to 5.25 V and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Features a sea-of-modules architecture with DirectConnect and FastConnect routing for deterministic timing and high resource utilization.
• Includes hot-swap compliant I/Os that tristate during power-up/down without requiring voltage sequencing.
• Supports configurable I/O standards including 3.3V PCI, 3.3V LVTTL, and 2.5V LVCMOS2.
• Provides boundary scan testing compliance with IEEE Standard 1149.1 (JTAG) and internal probing capabilities via Silicon Explorer II.

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive logic integration replacing multiple CPLDs

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with Actel Designer software versions supporting the SX-A family. Confirm RoHS compliance status if required for assembly processes. Check for any product discontinuation notifications or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this model for designs requiring automotive temperature stability (-40°C to +125°C) and nonvolatile antifuse technology. The 256-pin FBGA package suits applications needing high I/O density within a compact footprint. Consider the 250 MHz internal clock speed for complex state machines and datapath logic. Verify that the 203 available I/Os meet interface requirements for target peripherals.

Part Context

This part belongs to the SX-A Automotive Family FPGAs, which are designed for harsh environments. The 'A' suffix denotes the automotive temperature grade, while 'FG' indicates the Fine Pitch Ball Grid Array package. The '256' specifies the pin count. This series utilizes Actel's patented metal-to-metal antifuse interconnects for permanent configuration and security.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as A54SX32A-FFGG256A, provided timing requirements are met. Cross-family migration to higher capacity devices like A54SX72A requires significant schematic and layout redesign due to different pin counts and architectural differences.
