ROCKCHIP RK3562: High-Performance SOC for Consumer and Industrial Computing Applications

Keywords: ROCKCHIP, RK, RK3562, RK3566, RK3568, SOC, IPC, AIOT, ARM A53

Introduction to the RK3562

The RK3562 is a versatile System-on-Chip (SOC) product launched by ROCKCHIP in the second quarter of 2023. Built on advanced 22nm process technology, it features low CPU junction temperature (Tj) during operation, enabling fanless applications. With support for multiple peripherals and numerous IO ports, the RK3562 meets the requirements of various applications.

The RK3562 is powered by a quad-core A53 CPU delivering 17K DMIPS computing power, along with a G52 GPU and an integrated independent NPU. It supports hardware encoding and decoding, offers moderate expandability, and includes interfaces for PCIe, CAN, UART, SPI, I2C, as well as dual network ports (RGMII and RMII). It also supports heterogeneous multi-core operation with A-core microsecond-level response and M0 nanosecond-level response.

A variant, the RK3562J, is available for industrial-grade applications, supporting an operating temperature range of -40°C to 85°C, though it excludes the NPU. The RK3562J is ideal for industrial applications such as power concentrators, energy controllers, dedicated transformer collection terminals, HMI, PLC control, and various gateway devices.
