RZ/A1LC

RZ/A1LC is the most cost-effective part in the RZ/A1 family with an ARM® Cortex®-A9 core running at 400MHz and 2MB of on-chip SRAM to support frame-buffers on-chip.

 

With 2MB on-chip SRAM and a 400MHz ARM® Cortex®-A9 core, the RZ/A1LC is a great replacement for MCU designs that are trying to achieve MPU levels of performance. RZ/A1LC enables very compact embedded designs without the need to worry about memory procurement and memory EOL. Enabled for support with Linux, RTOS or Bare-metal, this is the ideal device for designing Intelligent IoT End Point devices with compactness and high performance. Supported in a 176 pin BGA package with SDRAM interface to expand up to 128MB of external memory.
