BOS Semiconductor unveils Eagle-N auto chip with Tenstorrent NPU

BOS Semiconductor was founded in May 2022 by Jaehong Park, who spent 22 and a half years at Samsung Electronics and ultimately served as EVP of its automotive and custom SoC business before starting the company. That background helps explain why Eagle-N is manufactured on Samsung's 5nm process, and why the startup has focused on automotive AI chips rather than general-purpose processors.

The chip's NPU comes from Tenstorrent, with which BOS announced a partnership in October 2023 to develop automotive chips. Eagle-N's NPU is based on Tenstorrent's Tensix cores, and BOS appears to have concentrated on integrating that NPU into an automotive SoC rather than designing the NPU itself. Eagle-N was demonstrated at CES 2025, and BOS has also listed other products including Eagle-A and N1301/N1501, though which came first is not clear.

The SoC pairs a Quad Cortex-A53 host with a Tensix Trinity NPU and a Cortex-M7-based Security Island, and includes UCIe x32, PCIe Gen5 x8, and LPDDR5x memory totaling 12 channels at 16 bits with roughly 204GB/s of bandwidth. Tenstorrent's white paper lists a 1.4GHz Tensix Neo core at 22.4TOPS for INT8, which appears to be a four-core cluster figure; at roughly 5.5TOPS per core, 48 cores would come to about 264TOPS, close to the 250TOPS figure cited for Eagle-N.
