Family Overview
FPAI is a heterogeneous reconfigurable chip that puts FPGA fabric, an AI accelerator and a CPU on a single die. The line spans 4 to 128 TOPS and is programmed through the ICraft toolchain, which covers model compilation down to the fabric.
- CPU + NPU + FPGA on one die
- 4 to 128 TOPS
- ICraft toolchain
- Distributed LLM inference
Applications
Edge inference, video analytics, industrial inspection and distributed LLM serving where a CPU, an NPU and reconfigurable logic must share one die.
Design Notes
- TOPS figures are peak INT8 unless stated otherwise. Real throughput depends on the model's operator mix — convolution-heavy networks reach the peak far more readily than attention-heavy ones.
- Model compilation goes through ICraft. Operator coverage is the practical limit, so check that your network's layers are supported before sizing the part.
- Host and device memory are separate. For large models, plan the weight partitioning and the PCIe or Ethernet link budget between cards.
- Power scales with the number of active cores. The headline figure assumes a workload profile; measure against your own model rather than the datasheet ceiling.
Common Questions
How much logic does the FMZQ400TAI provide?
451K programmable logic cells. The fabric also carries the BRAM and DSP resources listed above.
What package is the FMZQ400TAI in?
FCBGA1924, 45×45 mm. Check the pin-out for the transceiver and HPIO assignment before layout.
Which EDA toolchain supports the FMZQ400TAI?
Procise for the FM7 family, Vulture for FM9, and ICraft for FPAI. The PSoC line is supported within the same flow as the FPGA family it derives from.
