EZR32LG330 Data Sheet

System Overview

3. System Overview

3.1 Introduction

The EZR32LG330 Wireless MCUs are the latest in the Silicon Labs family of wireless MCUs delivering a high-performance, low-energy

wireless solution integrated into a small form factor package. By combining a high performance sub-GHz RF transceiver with an energy

efficient 32-bit ARM Cortex-M3, the EZR32LG family provides designers with the ultimate in flexibility with a family of pin-compatible

parts that scale from 64 to 256 kB of flash and support Silicon Labs EZRadio or EZRadioPRO transceivers. The ultra-low power operat-

ing modes and fast wake-up times combined with the low transmit and receive power consumption of the sub-GHz radio result in a

solution optimized for low power and battery powered applications. For a complete feature set and in-depth information on the modules,

refer to the EZR32LG Reference Manual.

The EZR32LG330 block diagram is shown below.

Figure 3.1. Block Diagram

3.1.1 ARM Cortex-M3 Core

The ARM Cortex-M3 includes a 32-bit RISC processor which can achieve as much as 1.25 Dhrystone MIPS/MHz. A Memory Protection

Unit with support for up to 8 memory segments is included, as well as a Wake-up Interrupt Controller handling interrupts triggered while

the CPU is asleep. The EZR32 implementation of the Cortex-M3 is described in detail in the EZR32 Cortex-M3 Reference Manual.

3.1.2 Debugging

These devices include hardware debug support through a 2-pin serial-wire debug interface and an Embedded Trace Module (ETM) for

data/instruction tracing. In addition there is also a 1-wire Serial Wire Viewer pin which can be used to output profiling information, data

trace and software-generated messages.

3.1.3 Memory System Controller (MSC)

The Memory System Controller (MSC) is the program memory unit of the EZR32LG microcontroller. The flash memory is readable and

writable from both the Cortex-M3 and DMA. The flash memory is divided into two blocks: the main block and the information block.

Program code is normally written to the main block. Additionally, the information block is available for special user data and flash lock

bits. There is also a read-only page in the information block containing system and device calibration data. Read and write operations

are supported in the energy modes EM0 and EM1.
