The useful part

Renesas has expanded its RZ/G Series with the RZ/G3L and RZ/G3SE, two new 64-bit MPUs for HMI and IoT edge systems. Both devices integrate up to four Arm Cortex-A55 application cores clocked at up to 1.2 GHz and a 200 MHz Arm Cortex-M33 real-time coprocessor. The RZ/G3L integrates an Arm Mali-G31 3D GPU and H.264 video codec for HMI applications like retail terminals and medical devices.

How it works

  • The RZ/G3SE removes the GPU and video codec and is designed for IoT devices with basic display requirements, including EV chargers and industrial gateway devices.
  • Renesas RZ/G3L and RZ/G3SE specifications: MPU core CPU Quad-core or Dual-core Arm Cortex-A55 @ up to 1.2 [...] The post Renesas RZ/G3L & RZ/G3SE – Ultra-low-p...

Details worth keeping

The two chips are pin-to-pin compatible but target different applications.
