Specification

2.2.1

ARM® CortexTM-M3 and SRAM

The ARM® CortexTM-M3 is a generation of ARM processors for embedded systems. It has

been developed to provide a low-cost platform that meets the needs of MCU implementa-

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

computational performance and an advanced system response to interrupts.

The ARM® CortexTM-M3 processors feature exceptional code-efficiency, delivering the

high performance expected from an ARM core, with memory sizes usually associated

with 8- and 16-bit devices.

The devices have embedded ARM core and are compatible with all ARM tools and soft-

ware.

2.2.2

Memory

512K Bytes of embedded Flash memory.

2.2.3

SRAM

128K Bytes of embedded SRAM.

2.2.4

Clocks and startup

When the system is powered up, the default clock is from PLL with the resource from

HSE 48 MHz oscillator. An external 2

∼ 24 MHz clockcan also be configured to monitor

the system during power up phases. If the system fails at power up, then the device

will switch back to HSI clock directly. At the same time, a software interrupt can also be

generated if it is enabled.

Several prescalers allow the application to configure the frequency of the AHB and the

APB domains. The maximum frequency of the AHB and the APB domains is 168MHZz.Refer

to figure 3 for the clock drive block diagram.
