A54SX16-2VQ100 概述
A field-programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer wires together after manufacturing. Within the programmable logic hierarchy, the A54SX16 sits in the high-density antifuse FPGA class: FPGA -> programmable logic device -> application-specific integrated circuit (ASIC) alternative. Antifuse technology programs connections permanently at power-up programming, providing nonvolatile, radiation-tolerant configuration without an external boot PROM.
Key features include a sea-of-modules architecture that shortens design cycles, 16K system gates (924 logic cells), dual-voltage operation that separates the 5V-tolerant I/O ring from the 3.3V core, and a -2 speed grade supporting system toggle rates up to 320 MHz. The antifuse fabric consumes very low static power compared with SRAM FPGAs and is immune to configuration bitstream readback, giving inherent design security.
Technically, the SX family uses a 0.35 um CMOS process with Actel's proprietary Act1/Act2-style logic modules and antifuse interconnect. The VQ100 package provides 81 available I/O on a 0.5 mm lead pitch, and the dual-rail scheme allows direct interface to legacy 5V TTL systems while running the core at 3.3V for power savings.
Typical applications include glue logic integration and ASIC prototyping, industrial control and automation interfaces, telecommunications line-card support logic, and legacy avionics and defense system sustainment where the permanent antifuse configuration is preferred.
A key design consideration: this part is obsolete and RoHS non-compliant (tin-lead leads), so new designs should target the RoHS-compliant SX-A (A54SX16A) family, while existing designs should secure lifetime-buy stock.

典型应用
A54SX16-2VQ100 适用于 6 应用s: Glue Logic Integration and ASIC Prototyping, Industrial Control and Automation, Telecommunications Line Cards, Legacy Avionics and Defense Sustainment, Test and Measurement Instrumentation, RoHS Remediation of Existing SX-Based Boards.
Glue Logic Integration and ASIC Prototyping
The A54SX16-2VQ100 consolidates address decoders, bus transceivers, state machines, and interface adapters that would otherwise occupy dozens of 74-series devices. Its 24,000 antifuse gates and 81 user I/O provide enough capacity to absorb surrounding SSI/MSI glue logic in a single 14x14 mm TQFP, cutting board area and assembly cost. The 5V-tolerant I/O ring interfaces directly with legacy TTL buses, while the 3.3V core keeps static power low. Because the antifuse fabric is programmed once and never loses configuration, a prototype compiled in the same flow as production silicon behaves identically at power-up, making the SX family a low-risk ASIC prototyping vehicle.
推荐
Industrial Control and Automation
In PLC I/O cards, motor-control interface panels, and sensor aggregation boards, the A54SX16-2VQ100 provides deterministic, instantly-available logic with no configuration boot delay - critical for systems that must be active within microseconds of power application. The 81 user I/O handle parallel encoder inputs, limit switches, and relay drive interfaces at 5V logic levels, while the -2 speed grade's 320 MHz toggle capability far exceeds industrial timing needs, giving generous timing margin over the 0C to +70C range. The permanent antifuse configuration also eliminates configuration-corruption field failures caused by radiation or power glitching, a common reliability concern with SRAM FPGAs on electrically noisy factory floors.
推荐
Telecommunications Line Cards
Telecom line-card support logic - framing interface glue, backplane handshaking, and LED/alarm control - benefits from the A54SX16-2VQ100's combination of fast deterministic interconnect and 5V-tolerant I/O that talks directly to legacy backplane signalling. The sea-of-modules architecture delivers predictable pin-to-pin delays, simplifying timing closure across the 81 user I/O. Low static power from the antifuse fabric reduces card-level thermal budget pressure in high-density shelves. For sustainment of NEBS-era equipment still specifying the original SX family, the 100-TQFP VQ100 package fits the existing footprint, and recompiled green variants (VQG100) drop onto the same land pattern when RoHS rework is required.
推荐
Legacy Avionics and Defense Sustainment
Although the commercial A54SX16-2VQ100 is rated 0C to +70C, the SX antifuse architecture persists in defense and avionics sustainment programs because its configuration cannot be upset by radiation-induced bit flips - there are no configuration bits to corrupt. Design security is inherent: the programmed netlist cannot be read back, protecting proprietary algorithms in deployed hardware. For extended-temperature programs, the A54SX16-2VQG100I provides -40C to +85C operation in the identical 100-TQFP footprint, requiring only recompilation. Lifetime-buy strategies typically pair the commercial part with its industrial I-grade sibling to cover all deployed environmental envelopes from one design database.
推荐
Test and Measurement Instrumentation
Bench instruments, interface adapters, and production test fixtures use the A54SX16-2VQ100 as a fast, reprogrammable-at-design-time (one-time programmable per unit) controller of timing generators, comparators, and pattern muxes. The -2 speed grade supports toggle rates up to 320 MHz, adequate for high-speed clock division and edge-aligned pattern generation, while deterministic antifuse interconnect guarantees repeatable skew performance unit-to-unit - important for calibrated measurements. Dual 3.3V/5V rails let the FPGA bridge between a 5V TTL test fixture world and a 3.3V digital control section without level shifters across its 81 I/O.
推荐
RoHS Remediation of Existing SX-Based Boards
Boards designed around the original tin-lead A54SX16-2VQ100 face component obsolescence under RoHS directives. Because the Pb-free (A54SX16P-2VQ100) and green (A54SX16-2VQG100) variants share the exact same die, pinout, and 100-TQFP footprint, remediation requires no PCB respin: swap the MPN, recompile the same design source, program the new antifuse device, and the board is RoHS-compliant. The only verification needed is solder-profile compatibility with the lead-free finish and a timing recheck if stepping from -2 to -1 speed grade. This makes the SX family one of the cleanest FPGA migration cases available for legacy-product compliance programs.

设计说明
Provide separate decoupling for the two supply rails: 0.1 uF ceramic per 3-4 VCC/VD pins plus at least 10 uF bulk on both the 3.3V core rail and the 5V I/O rail. Because this is an antifuse device, static current is very low, but dynamic I/O switching current on the 5V ring with 81 outputs can be significant - estimate ring current from your I/O macro count and load capacitance before sizing the 5V regulator. Estimated: 40 simultaneously switching outputs at 20 pF load, 10 MHz average toggle, draws roughly 40 x 20pF x 5V x 10MHz = 40 mA of dynamic current on VCI.
Antifuse devices are one-time programmable: a design error discovered after programming scraps the device. Always complete full simulation and static timing analysis at the -2 speed grade in Microsemi Designer before programming. Never substitute a -1 speed grade part without re-running timing closure, as -1 delays are slower and a -2-closed design can fail at -1. Also note the 0C to +70C commercial range - deploying this exact MPN in an unheated outdoor enclosure violates the datasheet limits; select the VQG100I industrial variant instead.
The 100-TQFP uses a 0.5 mm lead pitch; specify a solder-mask-defined land pattern per the Microchip/Microsemi package drawing and allow 1-2 extra mils of stencil reduction to prevent bridging. Use the exposed pin-1 dot for orientation and keep high-speed clock traces short with series termination near the driver. If migrating to the Pb-free A54SX16P-2VQ100 for RoHS, the land pattern is unchanged - only the assembly solder profile (SAC305, peak ~245-250C) needs updating.
The 5V I/O ring can source substantial edge rates; for long backplane or cable runs, enable the slew-limited output option in the I/O macro attributes, or add 22-33 ohm series resistors on outputs driving unterminated lines. Ground bounce across 81 outputs is best controlled by assigning switching banks evenly across the four sides of the TQFP and preserving the datasheet's dedicated ground pin frame - do not reassign power/ground pins in the constraint file.
合规信息
RoHS non-compliant per Microchip USA product data (tin-lead lead finish). Pb-free green variants (VQG100 / PQG suffixes) exist in the same family for compliant builds.
