Upbeat Technology, in collaboration with SiFive, has introduced UP201 and UP301 always-on AI MCUs for ultra-low-power AI and IoT applications such as wearables, drones, and sensor-based systems. The UP201 is designed for compact, battery-driven devices such as smartwatches, hearing aids, and IoT sensor nodes, whereas the UP301 targets AI and vision-based applications for more complex edge systems such as smart glasses, robotics, and industrial AI equipment. Both chips feature a dual-core RISC-V architecture. The SiFive E21 lightweight core is Always-On (AON), managing continuous low-power sensing, whereas the SiFive E34 performance core activates for higher workloads. The MCUs also integrate a 2.5D GPU and various I/O options. UP201 and UP301 MCU specifications: CPU cores (SiFive Essential RISC-V IP cores) E21 core in Always-On (AON) domain for continuous low-power sensing E34 performance core in the Non-AON domain for higher workloads Up to 400 MHz operating frequency Up to 717 DMIPS performance Near-threshold […]
