3.2.

On-chip memory

 Up to 3840KB of on-chip flash memory for instruction and data.



Up to 512 KB of configurable SRAM for ITCM/DTCM/AXI SRAM.

The GD32H757xx has up to 3840KB of on-chip flash memory for instruction and data. The

flash memory consists of 3840KB main flash organized into 960 sectors with 4KB and 64KB

information block. Each sector can be erased individually.

The GD32H757xx series contain up to 512KB of on-chip SRAM (AXI SRAM), 4KB of backup

SRAM and up to 512KB RAM shared by ITCM/DTCM/AXI SRAM. All of AHB SRAM support

byte, half-word (16 bits), and word (32 bits) accesses. The on-chip SRAM (AXI SRAM)

support byte, half-word (16 bits), word (32 bits) and double words (64 bits) accesses. SRAM0

and SRAM1 can be accessed by almost all AHB masters. The backup SRAM (BKPSRAM) is

implemented in the backup domain, which can keep its content even when the VDD power

supply is down.

Table 2-2. GD32H757xx memory map shows the memory map of the GD32H757xx series

of devices, including Flash, SRAM, peripheral, and other pre-defined regions.
