XMOS takes four core microcontroller below $3
XMOS has launched a four core microcontroller for under $3 to open up multicore designs to low quantity and distribution customers.

The xCORE XS1-L4-64 integrates four 32bit logical processor cores with 64KB of SRAM at a price that is comparable with competing single-core devices.
“The xCORE L4 offers 400MIPS performance at the price point of other manufacturers’ 40 or 50MIPS products,” said Ali Dixon, Director of Product Marketing and co-founder of UK-based XMOS. “Embedded designers working on high-volume applications can now add more features, including those that require real-time determinism, with software that is functionally safe. We believe it’s a real game-changer.”
Priced at just $2.95 in 100‑unit quantities through global distributors, the L4 provides an entry-level platform for designers considering multicore technology for the first time. It is pin-compatible with other members of the xCORE family, opening up the opportunity to cost reduce existing designs.
The new device is aimed at accurate stepper motor control, industrial networking and motion control. With 64bit precision DSP capability, it is also particularly well suited for signal conditioning tasks and applications such as control that combine cost-sensitivity with high performance demands. The xCORE L4 will also help drive the growing trend towards distributed intelligence in embedded design, by allowing developers to locate low-cost processing and communications closer to system nodes such as sensors and actuators.
“The L4 breaks new ground by combining low unit cost, real-time deterministic execution, multicore performance, on-chip DSP and the industry’s fastest response times,” said Nigel Toon, President and CEO, XMOS. “At 400 MIPS it offers a price/performance ratio unbeaten in the world of C-programmable embedded devices. Just as importantly, we provide the design tools engineers need to harness this performance – making the move to multicore technology an instinctive and natural experience.”
The XS1-L4-64 comes in a 48-pin package that is pin-compatible with the existing 6-core L6-64 and the 8-core L8-64 xCORE devices, allowing designers to take a platform-based approach that permits early implementation of emerging technologies and standards, future-proofing and the addition of new features as requirements evolve.
