The PTR54H20 is an ultra-low-power, Bluetooth multi-protocol system-on-module (SoM) designed to fit within the size of a coin cell battery. Built on the Nordic nRF54H20 (22nm process), the module integrates two Arm Cortex-M33 processor cores, two RISC-V coprocessors, and a dedicated security encryption processor. With a clock frequency of up to 320 MHz, each processor is optimized for specific workloads. The module incorporates advanced security features to counteract diverse threats effectively.Equipped with ample integrated internal memory, the PTR54H20 delivers outstanding performance and sufficient capacity, making it ideal for applications requiring machine learning (ML) models and edge sensor fusion.
