AT40K10AL-1BQU Обзор
The Microchip Technology (formerly Atmel) AT40K10AL-1BQU is a CMOS Field Programmable Gate Array from the AT40KAL series, integrating 10,000 system gates with up to 50,000 usable gates and 576 logic cells in a 144-pin LQFP package. It operates from a 3.0V to 3.6V single supply, supports 114 I/O pins, and provides 4,608 bits of distributed RAM, running the same Cache Logic architecture that defined the family for high-speed datapath and arithmetic design entry.
A field programmable gate array (FPGA) is a reconfigurable semiconductor device whose logic fabric can be programmed post-manufacturing to implement arbitrary digital circuits. In the broader taxonomy, the AT40K10AL-1BQU sits at: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Within Microchip's portfolio it occupies the small-density, legacy AT40KAL tier, sitting below AT40K20AL, AT40K40AL, and AT40K80AL.
Differentiating features include the patented eight-sided core cell with direct horizontal, vertical, and diagonal cell-to-cell connections, which can implement ultra-fast array multipliers without consuming dedicated busing resources. The device advertises a 1 ns combinatorial pin-to-pin delay class, 2.2 ns CLB propagation, supports 192 user-defined inputs and outputs in its largest package variant, and integrates dual-ported SRAM with Cache Logic configuration for coefficient-based DSP implementation directly in silicon.
Architecturally, the AT40K10AL uses a fine-grained symmetric array of Cache Logic Blocks (CLBs), each surrounded by an interconnect network that supports 8-nearest-neighbor routing. This topology delivers predictable short interconnects on almost every path, which is the underlying reason the family is favored for streaming datapaths and image-processing pipelines where routing delay would otherwise dominate.
Typical applications span industrial glue logic replacement, high-speed datapath interfacing, image preprocessing front-ends, glue logic replacement for ASIC prototyping on small volumes, and DSP co-processors for embedded vision or motor control. The wide 3.3V IO tolerance lets it bridge 5V legacy buses with level shifters.
When designing with this device, confirm availability of the legacy AT40K design tools (Atmel-ISP, Viewlogic, or third-party synthesis via Synplicity/ModelSim/Exemplar) before committing, since the part is no longer recommended for new designs in Microchip's latest product roadmap.

Типичное применение
AT40K10AL-1BQU подходит для 6 применениеs: Industrial Glue Logic Replacement, High-Speed Datapath Arithmetic, Image Preprocessing Front-End, ASIC Prototyping Bridge, Embedded DSP Co-Processor, Legacy Industrial Control Logic.
Industrial Glue Logic Replacement
Replaces legacy TTL/CMOS logic on industrial backplanes. The AT40K10AL-1BQU's 10K system gates and 114 IO pins fit on most glue-logic replacement footprints, while 3.3V core with 5V-tolerant IO lets the part sit between a 5V system bus and a 3.3V controller. Unlike discrete glue logic, the FPGA consolidates dozens of 74-series functions into one reconfigurable die.
Рекомендуется
High-Speed Datapath Arithmetic
Implements multipliers, MAC units, and FIR filters using the patented eight-sided core cell with diagonal routing. The 1 ns combinatorial delay delivers sub-2.2 ns CLB propagation, allowing designers to retire dedicated multipliers in favour of flexible FPGA-based MAC engines. Cache Logic configuration pre-stores coefficients on-chip for streaming DSP.
Рекомендуется
Image Preprocessing Front-End
Buffers and pre-processes image data on the FPGA before downstream DSP/MCU analysis. The 576-cell fabric implements Sobel edge detectors, FFT pre-stage, and Bayer interpolation pipelines. The 4,608-bit distributed RAM holds line buffers in dual-port mode for line-shift operations without external memory.
Рекомендуется
ASIC Prototyping Bridge
Acts as a verification bridge before taping out dedicated ASICs. Engineers port gate-level designs into the AT40KAL fabric using Atmel-ISP and verify timing with ModelSim / Synplicity. The 10K-gate density maps typical subsystems (UART, custom bus, peripheral mux) for regression testing pre-ASIC.
Рекомендуется
Embedded DSP Co-Processor
Operates as a co-processor alongside an MCU or microcontroller for parallel DSP tasks. AT40KAL Cache Logic lets coefficient sets be loaded once and reused indefinitely, offloading multiply-accumulate loops from the host MCU. The 3.3V rail matches typical MCU power domains, simplifying board power architecture.
Рекомендуется
Legacy Industrial Control Logic
Maintains installed industrial machines that rely on discontinued AT40K logic. The AT40K10AL-1BQU's 3.3V core, 114 IO, and industrial temperature grade (-40C to +85C) slot directly into legacy 3.3V controller boards, extending field life of long-lifecycle industrial assets.

What is the logic capacity of the AT40K10AL-1BQU?
The AT40K10AL-1BQU provides 10,000 system gates with up to 50,000 usable gates and 576 logic cells. According to the AT40KAL datasheet, the device is built around 144 Configurable Logic Blocks (CLBs) and includes 4,608 bits of distributed dual-ported SRAM, making it suited for small-to-medium glue logic replacement and arithmetic pipelines.
What is the operating voltage of the AT40K10AL-1BQU?
The AT40K10AL-1BQU operates from a single 3.0 V to 3.6 V supply and is specified for industrial temperature -40C to +85C. The 3.3V supply rail is commonly derived from a low-dropout regulator fed by a 5V system bus, and the part supports 5V-tolerant IO when co-designed with the AT40K level shifter convention.
Is the AT40K10AL-1BQU suitable for new designs in 2026?
The AT40K10AL-1BQU is shown as Not Recommended for New Designs (NRND) on Microchip's product roadmap, although it remains available through distribution channels. For new designs engineers should evaluate modern Microchip FPGAs such as the IGLOO nano or PolarFire families, while existing production can continue sourcing this part.
What package does the AT40K10AL-1BQU use?
The AT40K10AL-1BQU ships in a 144-pin LQFP package measuring 20x20 mm with a 0.5 mm pin pitch. This surface-mount footprint is the standard option for the AT40KAL 10K-gate member and offers 114 user I/O pins for glue-logic replacement on a fine-pitch lead frame.
What is the difference between AT40K10AL and AT40K20AL?
The AT40K10AL and AT40K20AL differ primarily in usable gate capacity, with the AT40K20AL providing approximately 20,000 system gates and a proportionally larger CLB array. Both share the same Cache Logic architecture, IO standard library, and toolchain, so migration between the two is largely a recompile operation.
Where can I buy the AT40K10AL-1BQU online?
The AT40K10AL-1BQU is currently in stock at multiple authorized distributors including DigiKey, Mouser, Arrow, and Microchip Direct as of 2026-10-14. Pricing at qty-1 starts near 38.52 USD and drops to roughly 19.45 USD at qty-1000, with stock dropping quickly given NRND status.
What is the price of AT40K10AL-1BQU at 100 pieces?
At qty-100 the AT40K10AL-1BQU prices around 28.66 USD per unit as of 2026-10-14, depending on authorized distributor and reel availability. Volume quotes above 1,000 pieces can drop below 19.45 USD, but lead times have lengthened due to part NRND status.
What is the lead time for AT40K10AL-1BQU orders?
Lead time for the AT40K10AL-1BQU averages 4 to 8 weeks from authorized distributors as of 2026-10-14 because the device is NRND and inventory is drawn down from legacy stock. Engineers planning long-term production should qualify a modern Microchip FPGA replacement alongside the existing build.
Is the AT40K10AL-1BQU still in stock?
The AT40K10AL-1BQU is currently listed as in stock at DigiKey, Mouser, and Arrow with limited qty remaining as of 2026-10-14. Inventory will continue to shrink because the part is NRND, so engineers should request a lifetime-buy quote if a long-term supply is required.
AT40K10AL-1BQU vs XC6SLX9 - which is better for glue logic?
The AT40K10AL-1BQU is suitable for legacy glue-logic tasks at 3.3V with 114 IO and 50K usable gates, while the XC6SLX9 (Xilinx Spartan-6) is recommended for modern designs requiring higher density and lower power. Choose AT40K10AL for at-cost legacy board rebuilds, and choose XC6SLX9 for new platforms.
AT40K10AL-1BQU vs AT40K20AL-1BQU - which should I choose?
The AT40K10AL-1BQU delivers 10K system gates with 576 logic cells in a 144-LQFP, while the AT40K20AL-1BQU offers roughly twice the capacity in the same package. Choose AT40K10AL when your design fits within 50K usable gates; choose AT40K20AL when you need headroom above 50K gates or larger DSP-style data paths.
When should I choose AT40K10AL-1BQU over the AT40K40AL?
Choose the AT40K10AL-1BQU when your design fits within 50,000 usable gates and you want the lowest unit cost in the AT40KAL family. Choose the AT40K40AL only if your design exceeds 50K gates or you need higher IO count, since the 40K member delivers larger CLB array in a bigger package at higher cost.
What is the best drop-in replacement for AT40K10AL-1BQU?
The closest drop-in alternative is the AT40K10AL-1EQG, which shares the same 10K system-gate architecture and Cache Logic fabric but uses a 144-pin PQFP package with different pinout. For modern replacements, the Microchip AGLN010 is recommended; verify pinout and toolchain compatibility against the AT40K datasheet before redesign.

Руководство по выбору
Choose AT40K10AL-1BQU when you need a 10K-gate, 3.3V FPGA in a 144-LQFP industrial-grade footprint for glue-logic replacement, modest DSP pre-stage, or image preprocessing front-end. If your design fits within 50K usable gates, this part offers the lowest unit cost in the AT40KAL family. Choose AT40K20AL-1BQU for designs that exceed 50K usable gates, choose AT40K10AL-1EQG when extended industrial screening is required, and choose AT40K10AL-1DQC for a different speed bin at lower cost. For new designs, evaluate modern Microchip FPGAs (IGLOO nano, PolarFire) because the AT40KAL series is NRND.

Заметки по проектированию
Decouple each VCC and VCCIO bank with 0.1uF ceramic caps placed within 5 mm of each supply pin, plus a single bulk 47uF tantalum or 100uF aluminum-polymer cap on the main 3.3V rail. The AT40KAL sequencing requires the 3.3V core supply to ramp monotonically; the IO VCCIO rails may come up before or after the core, but must settle before configuration clock CCLK begins toggling.
Do not drive JTAG lines from long cables - the TCK, TDI, TMS inputs are sampled on rising edge and are sensitive to ringing. Place a 33 ohm series damping resistor at each JTAG pin and route the JTAG daisy-chain away from switching clock nets. Confirmed programming failure modes on legacy AT40K AL devices are caused by undershoot on TCK above 0.5 V below ground.
Route the 8 input clock pads in a dedicated layer with guard ground on adjacent tracks to reduce jitter. Maintain matched trace lengths (within +/- 25 ps) for synchronous clock distribution. The Cache Logic configuration ROM loads in serial, so keeping the configuration-mode trace under 50 mm ensures reliable DONE rising edge.
