A54SX16P-1VQG100M 概述
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic through programmable interconnect and logic blocks. Within the programmable-logic hierarchy, the SX family sits in the one-time-programmable (OTP) antifuse category, a lineage that runs FPGA -> antifuse FPGA -> programmable logic IC -> semiconductor. Unlike SRAM-based FPGAs, antifuse devices retain their configuration permanently and are immune to configuration-bitstream upset, which is a key reason they persist in radiation- and security-sensitive programs.
Key features of the A54SX16P include the sea-of-modules architecture that Microsemi credits with simplifying design time and reducing power consumption, mixed 3.3 V and 5 V supply operation for legacy-interface compatibility, and 0.35 um CMOS technology with a two-dimensional flexible routing structure. The 81 available I/O support mixed-voltage interfacing in a compact 100-lead body with 0.5 mm lead pitch.
Technically, the device provides 1452 CLB-equivalent modules mapped to roughly 16,000 system gates and 924 usable cells. The -1 speed grade supports clock rates up to the 240 MHz class documented for the family, adequate for glue logic, bus bridging, and control-path designs. The antifuse fabric means the design is programmed once via Actel/Microchip programming hardware and cannot be reconfigured in-system.
Typical applications include military avionics and ground-system control logic, secure industrial controllers, bridge and bus-interface logic between 5 V legacy systems and 3.3 V subsystems, and replacements for obsolete ASIC or PAL/GAL glue logic in long-lifecycle programs.
Design consideration: antifuse FPGAs are one-time programmable, so functional verification and programming-yield planning are essential before committing hardware; design changes require new devices.

典型应用
A54SX16P-1VQG100M 适用于 6 应用s: Military Avionics Control Logic, 5V-to-3.3V Bus Bridge Logic, Secure Industrial Controllers, ASIC Prototype and Bridge Replacement, Test and Measurement Instrument Logic, Defense Ground Systems and Upgrades.
Military Avionics Control Logic
The A54SX16P-1VQG100M fits military avionics subsystems because its -M military screening and antifuse one-time-programmable fabric deliver configuration persistence and upset immunity that SRAM FPGAs cannot match without additional mitigation. Its 16,000 gates and 81 user I/O provide enough capacity for ARINC-style bus interfacing, discrete signal conditioning, and control-path logic in a single 100-pin VQFP. Mixed 3.3 V/5 V I/O operation lets it bridge legacy 5 V avionics signaling directly to 3.3 V digital subsystems without level translators. Because the configuration is fuse-based, there is no boot-up configuration time, an advantage in power-critical and deterministic-startup avionics rails.
推荐
5V-to-3.3V Bus Bridge Logic
The A54SX16P-1VQG100M is well suited to bridging legacy 5 V TTL/CMOS buses with modern 3.3 V subsystems, since the SX family explicitly supports mixed 3.3 V and 5 V supply operation on its 81 user I/O. Typical implementations integrate address decoding, byte-lane steering, wait-state generation, and bus multiplexing that would otherwise occupy multiple PAL/GAL and buffer devices. The 240 MHz-class family toggle performance easily covers peripheral bus timing, while the 100-pin VQFP with 0.5 mm pitch provides enough I/O for a 32-bit address/data path plus control signals. Consolidating glue logic into one antifuse FPGA also reduces board area and improves signal integrity versus discrete TTL chains.
推荐
Secure Industrial Controllers
In secure industrial controllers, the A54SX16P-1VQG100M's antifuse configuration cannot be read back or modified, protecting proprietary logic and IP from extraction - a documented motivation for antifuse technology in security-sensitive deployments. The 16,000-gate capacity handles state machines, encoders, tamper-response logic, and sensor interfaces, while the -M screening supports installations in extended-temperature environments such as unattended outdoor cabinets and factory floors near heat sources. The one-time-programmable nature also eliminates configuration-image storage, removing a common attack surface. Designers should plan verification thoroughly since fabric errors cannot be corrected after programming.
推荐
ASIC Prototype and Bridge Replacement
The A54SX16P-1VQG100M serves as a low-risk replacement for obsolete ASICs, EPLDs, and multi-chip glue logic in long-lifecycle programs, delivering roughly 16,000 system gates (1452 CLB modules, 924 cells) in one 100-pin VQFP. Microchip's sea-of-modules architecture simplifies design entry and reduces design cost, which matters when re-creating legacy functionality from limited documentation. The antifuse fabric gives ASIC-like persistence with no configuration device, preserving system boot behavior. For programs that later require volume cost reduction, the same design can be migrated up the SX family (A54SX32) or converted to a custom ASIC with verified fuse-level correspondence.
推荐
Test and Measurement Instrument Logic
Bench and automated test equipment benefits from the A54SX16P-1VQG100M's deterministic, configuration-free startup and 240 MHz-class internal toggle rates for counter, trigger, and timing-generator functions. The 81 user I/O support pattern-generator channels and instrumentation bus interfaces (e.g., parallel data capture), and 5 V-tolerant I/O connects directly to legacy instrument backplanes. Antifuse persistence ensures the instrument powers up operational in the exact programmed state - valuable for calibrators and reference instruments that must behave identically every cycle. The compact 100-pin VQFP fits instrument front-end boards where board area and signal routing density are constrained.
推荐
Defense Ground Systems and Upgrades
Defense ground systems, radar controllers, and obsolescence-driven COTS upgrades frequently standardize on -M screened Actel SX devices such as the A54SX16P-1VQG100M because program qualification cycles predate newer families and requalification of a new FPGA is costly. This device sustains those programs with a stable 0.35 um antifuse process, 16,000 gates, and documented military screening, letting sustainment teams buy identical-form-fit-function parts years after original deployment. Its 3.3 V/5 V mixed I/O preserves compatibility with legacy rack electronics during partial system upgrades. Stock availability via specialized distributors (e.g., ~110 pcs at Micro-Semiconductor) supports low-volume sustainment buys.

设计说明
The A54SX16P supports mixed 3.3 V and 5 V operation. Decouple each supply rail with 0.1 uF ceramic capacitors placed within 5 mm of the corresponding VQFP power pins, plus one bulk 10 uF per rail. Because antifuse FPGAs draw no configuration current at power-up, inrush is dominated by decoupling capacitor charging; verify supply sequencing if the 5 V I/O rail and 3.3 V core rail come from separate regulators. Estimate design-specific power with Microchip's SX power calculator using your placed design utilization and toggle rates rather than family averages.
This is a one-time-programmable antifuse device: once programmed via Silicon Sculptor-class hardware, the design can never be changed on that unit. Always order programming yield margin (antifuse programming has a small failure rate per device), verify the design fully in timing simulation, and freeze the fusemap revision before committing production quantity. Also confirm the ordering code suffix carefully: -1 vs -2 speed grade and -M vs -I temperature screening are orderable distinctions, and substituting an unscreened part into a -M socket violates program requirements.
The 100-pin VQFP has a 0.5 mm lead pitch, requiring solder-mask-defined pads approximately 0.3 mm wide per the datasheet footprint. Avoid routing traces under the package body without ground stitching, and fan out the 81 user I/O with short stubs to reduce reflections on 5 V legacy bus lines. Keep clock routing matched-length if multiple synchronous modules share the clock. Follow the Microchip 54SX datasheet package drawing exactly; third-party footprints for QFP-100 sometimes differ in pad geometry and can cause solder bridging at 0.5 mm pitch.
合规信息
One distributor listing references RoHS status but does not state the value for this exact ordering code. Military-screened (-M) legacy devices may be supplied with leaded finishes under defense exemptions; verify with Microchip product page for A54SX16P before compliance-critical procurement.
