Functional overview

3.1 ARM®-Cortex®-M0 core with embedded Flash and SRAM

The ARM® Cortex®-M0 processor is the latest generation of ARM processors for embedded

systems. It has been developed to provide a low-cost platform that meets the needs of MCU

implementation, with a reduced pin count and low-power consumption, while delivering

outstanding computational performance and an advanced system response to interrupts.

The ARM® Cortex®-M0 32-bit RISC processor features exceptional code-efficiency,

delivering the high-performance expected from an ARM core in the memory size usually

associated with 8- and 16-bit devices.

The W7500x family has an embedded ARM core and is therefore compatible with all

ARM tools and software.

Figure 1 shows the general block diagram of the W7500x family.

3.2 Memories

Program memory, data memory, registers and I/O ports are organized within the same linear

4-Gbyte address space.

The bytes are coded in memory in Little Endian format. The lowest numbered byte in a word

is considered the word’s least significant byte and the highest numbered byte the most

significant.

3.3 Boot modes

W7500x has three different boot modes that can be selected through the BOOT pin as shown

in Table 2.
