4.1.2 Electrical specification

4.1.2.1 CPU performance

The CPU clock speed is 64 MHz. Current and efficiency data is taken when in System ON and the CPU is

executing the CoreMark benchmark. It includes power regulator and clock base currents. All other blocks

are IDLE.

4.2 Memory

The application microcontroller has embedded 1024 kB flash and 256 kB RAM for application code and

data storage.

As illustrated in Memory layout on page 22, both CPU and EasyDMA are able to access RAM via the

AHB multilayer interconnect. See AHB multilayer interconnect on page 47 and EasyDMA on page

45 for more information about AHB multilayer interconnect and EasyDMA respectively. The LTE

modem can access all application MCU memory, but typically a small portion of RAM is dedicated to data

exchange between application MCU and the modem baseband controller.
