2.2.5

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 software

signature during runtime, to be compared with a reference signature generated at link-time

and stored at a given memory location.

2.2.6

Embedded SRAM

All STM32F40x products embed:

•

Up to 192 Kbytes of system SRAM including 64 Kbytes of CCM (core coupled memory)

data RAM

RAM memory is accessed (read/write) at CPU clock speed with 0 wait states.

•

4 Kbytes of backup SRAM

This area is accessible only from the CPU. Its content is protected against possible

unwanted write accesses, and is retained in Standby or VBAT mode.

2.2.7

Multi-AHB bus matrix

The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, Ethernet, USB

HS) and the slaves (Flash memory, RAM, FSMC, AHB and APB peripherals) and ensures a

seamless and efficient operation even when several high-speed peripherals work

simultaneously.
