A42MX09-VQG100A - 14K Gate 5V FPGA 83 I/O TQFP-100 | Microchip
MPN： A42MX09-VQG100A ✓ 啟用中A42MX09-VQG100A 概覽
A field-programmable gate array (FPGA) is a type of programmable logic IC that implements custom digital circuits through configurable logic blocks and interconnect fabric, positioned in the system hierarchy between fixed-function ASICs and simpler PLDs. The MX family is designed as a single-chip ASIC alternative and a low-cost platform for integrating legacy PLD designs, using antifuse program-once technology that is nonvolatile and inherently secure against readback.
Key features include 336 logic cells, a flexible 5.0V architecture tolerant of noisy industrial environments, dual supply rails (4.5V-5.5V core, 3.0V-3.6V I/O), and automotive temperature qualification. The 192 MHz maximum system speed supports moderate-speed control and glue-logic designs, while the nonvolatile antifuse fabric eliminates configuration PROMs and provides immediate power-on operation.
Architecturally, the 42MX device combines combinatorial and sequential logic modules within the 336 cells, connected by a segmented routing fabric. Being flash/antifuse based, it differs from SRAM FPGAs by retaining its configuration through power cycles without external boot devices.
Typical applications include automotive control modules, industrial automation, legacy PLD consolidation, ASIC prototyping, and mil/aerospace logic where single-chip integration and configuration security matter. Pricing as of 2026-08-30 is available from distributors including DigiKey, Mouser, and Octopart, typically supplied in trays.
Design tip: budget I/O banks carefully, as the 100-pin package exposes only 83 user I/Os; verify both 5V core and 3.3V I/O rail sequencing at power-up.

典型應用
A42MX09-VQG100A 適用於 6 應用s: Automotive Control Modules, Legacy PLD Consolidation, ASIC Prototyping, Industrial Automation Logic, Configuration-Secure Defense Logic, Communications Board Glue Logic.
Automotive Control Modules
The A42MX09-VQG100A fits automotive module control because its A suffix delivers -40C to +125C operation and its 5.0V antifuse core tolerates the noisy, load-dump-prone 12V vehicle environment. With 14,000 gates and 83 I/Os it consolidates discrete PLDs, address decoders, and I/O sequencing logic into one nonvolatile device. Programmed once via antifuse, it powers on instantly with no boot PROM, improving start-up reliability and configuration security in body control and powertrain auxiliary modules.
推薦
Legacy PLD Consolidation
Microchip markets the MX family explicitly as a platform for integrating legacy PLDs into a single low-cost device, and the A42MX09 is well suited: 336 cells absorb multiple 22V10-class PALs or GALs, while the 5V core matches the original PLD I/O signaling without level translation. The 83 user I/Os and 192 MHz toggle rate cover typical glue-logic timing. Because the antifuse fabric is nonvolatile, replaced boards behave identically to the original discrete-PLD design with immediate power-on configuration.
推薦
ASIC Prototyping
As a single-chip ASIC alternative, the A42MX09-VQG100A supports pre-silicon prototyping of moderate-complexity gate-array designs. Its 14,000 system gates map small gate-array netlists, and 0.45um process timing approximates mature ASIC speed targets at up to 192 MHz toggle. Antifuse programming provides a fixed, deterministic interconnect profile closer to an ASIC than SRAM-FPGA timing, making prototype results more transferable. The 100-pin VQFP also offers an economical package for low-volume prototype builds.
推薦
Industrial Automation Logic
In factory automation, the 5.0V core of the A42MX09-VQG100A interfaces directly with legacy 5V TTL sensor and PLC signal chains, avoiding the level shifters required by 3.3V FPGAs. The device handles encoder decoding, interlock logic, and sequencing within its 14,000 gates, while -40C to +125C operation survives panel and motor-drive thermal environments. Nonvolatile antifuse configuration means no configuration images to corrupt in electrically noisy plant settings, improving uptime.
推薦
Configuration-Secure Defense Logic
Antifuse FPGAs cannot be read back once programmed, making the A42MX09 attractive where bitstream confidentiality matters. Unlike SRAM FPGAs that load volatile bitstreams (a readback/exploitation surface), the MX device keeps its design physically encoded in antifuse links. With 14,000 gates, M-suffix and A-grade screening options, and -40C to +125C range, it supports defense and avionics glue logic, bus interfacing, and custom control where supply-chain and design IP security are prioritized over reconfigurability.
推薦
Communications Board Glue Logic
Networking and telecom line cards often need protocol glue logic - bus arbitration, address decode, and control-state machines - between a CPU and peripheral devices. The A42MX09-VQG100A provides 336 cells and 83 I/Os for this role, with the 192 MHz toggle rate comfortably covering PCI-style and backplane control timings. Its 3.0V-3.6V I/O rail connects directly to 3.3V logic, while the separate 5V core keeps timing stable across rail-tolerance windows, simplifying mixed-rail board power trees.

設計說明
The A42MX09-VQG100A requires two supply rails: a 5V core rail within 4.5V-5.5V and a 3.3V I/O rail within 3.0V-3.6V. Follow the Microchip MX datasheet power-up sequencing guidance to avoid latch-up during dual-rail ramp; decouple each rail with at least 10uF bulk plus 0.1uF ceramics at the package corners. Antifuse devices draw negligible static configuration current, but I/O switching current scales with toggle rate - budget supply accordingly near 192 MHz operation.
The 100-pin VQFP has a 0.5 mm pin pitch requiring solder-mask-defined pads of approximately 0.3 x 1.5 mm and a trace-to-trace clearance of 0.15-0.2 mm. Use the mechanical drawing in the Microchip 40MX/42MX datasheet for the exact 14x14 mm footprint. Connect all GND pins to a solid ground plane; avoid sharing the FPGA return path with high-current switching loads to preserve signal integrity on the 83 user I/Os.
Antifuse FPGAs are one-time programmable - once the A42MX09 is programmed via Libero SoC and the programming tool, the design cannot be erased or changed. Freeze and fully simulate your design before programming production devices, and order spare units for rework. Also note that only 83 of the 100 pins are usable I/Os; dedicated power, ground, and programming pins reduce usable routing, so verify I/O allocation early in design entry.
