Description
STM32F105xx, STM32F107xx
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.
●
Closely coupled NVIC gives low latency interrupt processing
●
Interrupt entry vector table address passed directly to the core
●
Closely coupled NVIC core interface
●
Allows early processing of interrupts
●
Processing of late arriving higher priority interrupts
●
Support for tail-chaining
●
Processor state automatically saved
●
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimal interrupt
latency.
2.3.6
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 20 edge detector lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 80 GPIOs can be connected
to the 16 external interrupt lines.
2.3.7
Clocks and startup
System clock selection is performed on startup, however, the internal RC 8 MHz oscillator is
selected as default CPU clock on reset. An external 3-25 MHz clock can be selected, in
which case it is monitored for failure. If failure is detected, the system automatically switches
back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full
