Description
Doc ID 15060 Rev 3
2.3
Overview
2.3.1
ARM Cortex-M3 core with embedded Flash and SRAM
The ARM Cortex-M3 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-M3 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 STM32F103xx performance line family having an embedded ARM core, is therefore
compatible with all ARM tools and software.
Figure 1 shows the general block diagram of the device family.
2.3.2
Embedded Flash memory
16 or 32 Kbytes of embedded Flash is available for storing programs and data.
2.3.3
CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of
the software during runtime, to be compared with a reference signature generated at link-
time and stored at a given memory location.
2.3.4
Embedded SRAM
Six or ten Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait
states.
2.3.5
Nested vectored interrupt controller (NVIC)
The STM32F103xx performance line embeds a nested vectored interrupt controller able to
handle up to 43 maskable interrupt channels (not including the 16 interrupt lines of
Cortex-M3) and 16 priority levels.
