Description
Doc ID 15274 Rev 4
13/95
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.
With its embedded ARM core, STM32F105xx and STM32F107xx connectivity line family is
compatible with all ARM tools and software.
Figure 1 shows the general block diagram of the device family.
2.3.2
Embedded Flash memory
64 to 256 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
20 to 64 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait
states.
2.3.5
Nested vectored interrupt controller (NVIC)
The STM32F105xx and STM32F107xx connectivity line embeds a nested vectored interrupt
controller able to handle up to 67 maskable interrupt channels (not including the 16 interrupt
lines of Cortex-M3) and 16 priority levels.
G
Closely coupled NVIC gives low latency interrupt processing
G
Interrupt entry vector table address passed directly to the core
G
Closely coupled NVIC core interface
G
Allows early processing of interrupts
G
Processing of late arriving higher priority interrupts
G
Support for tail-chaining
G
Processor state automatically saved
G
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimal interrupt
latency.
