STM32F413xG/H

Functional overview

3.7

Embedded SRAM

All devices embed 320 Kbytes of system SRAM which can be accessed (read/write) at CPU

clock speed with 0 wait states.

3.8

Multi-AHB bus matrix

The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs) and the slaves

(Flash memory, RAM, AHB and APB peripherals) and ensures a seamless and efficient

operation even when several high-speed peripherals work simultaneously.

CPU can access SRAM1 memory via S-bus, when SRAM1 is mapped at the address range:

0x2000 0000 to 0x2003 FFFF.

CPU can access SRAM2 memory via S-bus, when SRAM2 is mapped at the address range:

0x2004 0000 to 0x2004 FFFF.

CPU can access SRAM1 memory via I-bus and D-bus, when SRAM1 is remapped at

address 0x0000 0000 either by booting from RAM memory or by the remap mode.

CPU can access SRAM2 memory via I-bus and D-bus, when SRAM2 is mapped at the

address range: 0x1000 0000 to 0x1000 FFFF.

Performance boosts up, when the CPU access SRAM memory via the I-bus.
