A42MX16-1VQG100I - 24K-Gate Antifuse FPGA, 100-TQFP | Microchip
MPN： A42MX16-1VQG100I ✓ 啟用中A42MX16-1VQG100I 概覽
An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up programming time via antifuse links. Unlike SRAM FPGAs, antifuse programming is one-time and non-volatile, so the device retains its configuration with no external boot flash and inherently resists bitstream readback - a key reason the MX family serves as a single-chip ASIC alternative and legacy PLD consolidation platform. Within the power-management hierarchy of programmable logic, the MX family sits between simple CPLDs and high-density SRAM FPGAs.
Key features include the flexible 5.0V-tolerant MX architecture, low cost per gate for high-volume production, no configuration PROM requirement, and security through non-readable programming. The 100-TQFP surface-mount package supports standard reflow assembly, and the industrial temperature rating suits harsh environments.
Architecturally, the 42MX16 combines combinatorial and sequential logic modules connected through segmented antifuse interconnect, delivering deterministic timing without configuration-load transients. Performance tiers (119 MHz/198 MHz) reflect different routing resources.
Typical applications include glue logic integration, industrial control, legacy ASIC/PLD replacement, military/aerospace subsystems requiring configuration security, and high-volume consumer boards where per-unit cost dominates.
Design consideration: antifuse devices are one-time programmable - verify logic thoroughly in simulation and, ideally, on a companion deviice or emulation target before committing to production programming. Follow the DS2136 datasheet for power decoupling (0.1 uF per VCC pin) and JTAG boundary-scan programming requirements.

典型應用
A42MX16-1VQG100I 適用於 6 應用s: Legacy PLD / Glue Logic Consolidation, Industrial Control Systems, Configuration-Secure Military/Aerospace Logic, High-Volume Consumer/ASIC Replacement, Test & Measurement Interface Logic, Networking and Communication Backplanes.
Legacy PLD / Glue Logic Consolidation
The A42MX16-1VQG100I is explicitly targeted by Microchip at integrating legacy PLDs into a single low-cost device. With 24,000 gates and 608 logic cells, it absorbs multiple TTL, 74xx, and CPLD glue-logic chips, cutting BOM count and board area. Its 5V-tolerant I/O on a 3.3V/5V supply connects directly to legacy bus levels without level shifters, and antifuse non-volatility removes boot-flash cost. In high-volume retrofit boards, per-unit savings come from eliminated configuration devices and simplified assembly.
推薦
Industrial Control Systems
Industrial controllers benefit from the -40C to +85C industrial rating (I suffix) and deterministic antifuse timing. The A42MX16-1VQG100I implements sequencers, address decoders, and bus interfaces with no configuration-load delay at power-up - useful where deterministic startup matters. Its 119-198 MHz toggle capability covers common PLC and motor-control peripheral logic, while the 100-TQFP surface-mount package withstands vibration better than through-hole alternatives. Pair with industrial-grade transceivers for field-bus interfaces.
推薦
Configuration-Secure Military/Aerospace Logic
Antifuse programming cannot be read back, making the A42MX16 family attractive for defense and aerospace subsystems where bitstream security matters. The same die is offered in M-grade screening (e.g., A42MX16-1VQG100M), enabling path-to-military qualification without redesign. One-time programming also eliminates configuration upset from SEU-like boot faults in harsh environments. Logic capacity of 24K gates suits mission sequencers, telemetry formatters, and interface bridges.
推薦
High-Volume Consumer/ASIC Replacement
As a single-chip ASIC alternative on a mature 0.45 um CMOS process, the A42MX16-1VQG100I avoids ASIC NRE for volumes of thousands to millions of units. Microchip positions MX as a high-volume platform, and antifuse programming means every unit ships pre-configured with no firmware loading at board test. Unit cost is competitive at volume, and the 100-TQFP is standard reflow-compatible. Trade-off: no field updates - design must be frozen before production.
推薦
Test & Measurement Interface Logic
The JTAG boundary-scan chain (TDI-to-TDO register per DS2136) supports board-level interconnect test, making the A42MX16-1VQG100I useful as test-access and interface logic in ATE fixtures and measurement backplanes. Its 83 I/O terminate address/data/control buses, while deterministic antifuse delays simplify timing closure for strobe generation. Dual 3.3V/5V rails interface directly with both legacy TTL instruments and 3.3V logic analyzers without translation.
推薦
Networking and Communication Backplanes
With toggle rates to 198 MHz, the A42MX16-1VQG100I implements backplane address decoding, interrupt controllers, and simple protocol glue for telecom and networking cards. Its 5V-tolerant I/O suits legacy 5V backplane standards still common in industrial networking frames. Non-volatile antifuse configuration means cards enumerate instantly at power-up with no bitstream download, reducing boot time - valuable in redundant systems requiring fast failover.

主要差異化特點
- One-time-programmable non-volatile configuration (對比SRAM-based FPGAs (e.g., modern Microchip PolarFire))
- 5V-tolerant I/O on dual 3.3V/5V rails (對比A42MX16-1VQG100 commercial grade)
- Faster guaranteed timing option exists in same footprint (對比A42MX16-2VQG100I / A42MX16-3VQG100I)
設計說明
Decouple every VCC pin of the A42MX16-1VQG100I with a 0.1 uF ceramic capacitor placed within 2-3 mm of the pin, plus one bulk 10 uF per supply rail. The MX family runs dual 3.3V/5V rails; ensure both rails are present before or simultaneously with configuration-free operation (antifuse devices are active immediately at power-up, so brownout during ramp can cause logic misoperation). Refer to Microsemi datasheet DS2136 power-supply guidelines for exact sequencing tolerance.
Antifuse FPGAs are one-time programmable. There is no rework path after programming, so complete full timing simulation and functional verification in Microchip Libero/Designer before committing production units. Do not rely on last-minute HDL changes; a re-spin requires new physical devices. Reserve the JTAG chain (TDI, TDO, TMS, TCK) with test-point access for programming and boundary-scan production test.
With 83 I/O on a 100-pin TQFP, plan ground return paths: use at least 4-6 of the available GND pins and pour a solid ground plane under the device. For 198 MHz-class internal toggles appearing at I/O, add 22-33 ohm series resistors on fast outputs driving off-board loads to control ringing and EMI. Keep 5V-tolerant input stubs short when interfacing legacy TTL buses to avoid reflections.
