VPR: Nordic's First RISC-V Processor

VPR (pronounced “Viper”) is Nordic Semiconductor’s first RISC-V processor, landing in the new nRF54H and nRF54L lines of SoCs after their initial announcements in April and October of 2023 respectively. Readers of this blog are familiar with my long-running obsession interest in RISC-V (see my RISC-V Tips and RISC-V Bytes series). However, Nordic’s introduction of a RISC-V processor is particularly interesing to me as their lineup of microcontrollers is extremely popular in low power wireless domains, a common use case for Golioth customers.
