stm32f407的datasheet上写着:
Up to 192+4 Kbytes of SRAM including 64-
Kbyte of CCM (core coupled memory) data
RAM
还有一段:
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.
地址也不一样:
CCM data RAM 在:0x1000 0000,64KB
其他 在:0x2000 0000 128KB (memory map上还分两段)
大神给讲讲,都是干啥用的?
