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.

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.

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.
