Kria KD240 is a cost-effective DSP embedded solution

Sep 20, 2023 — by Giorgio Mendoza 611 views

AMD unveiled today a new embedded platform built around the Zynq UltraScale+ MPSoC and designed for motor controllers and real-time DSP applications including robotics, factory automation, power generation, EV charging station among others.

The Kria K24 System-on-Module is powered by the AMD Zynq UltraScale+ MPSoC with the following architecture:

  • Zynq UltraScale+ MPSoC — Quad-core Arm Cortex-A53 MPCore (up to 1.3 GHz), Dual-core Arm Cortex-R5F MPCore (up to 553MHz); 154K System Logic cells, 216 Block RAM blocks, 360 DSP slices; INT8(852 GOPs w/ B2304 DPU) DL processor

For connectivity, the KD240 features a Gigabit Ethernet interface (x1 PS GEM1) for standard networking needs. Additionally, it provides two Gigabit RGMII Ethernet interfaces with support for time-sensitive networking (TSN) and EtherCAT, making it suitable for industrial automation and control applications.

The carrier board also includes connectors for torque sensors, quadrature encoder interfaces (QEI), 3-phase motors, DC link, RS485, brake control, and a 1-wire interface, enhancing its versatility and adaptability for a wide range of applications.
