6 Memory Map
The 8051 family’s memory is organized in a Harvard structure, which means the program memory and
data memory are located in the separate address spaces. The 16 address lines can access up to 64k byte
space.
6.1 Program Memory Space
Since the 8032 core embedded in VT1620A is a ROMless version of 8051, all the program memories used
by VT1620A are considered as “External memory” in the point of view of 8032 core.

Note:
1. When boot from ROM is selected by the strapping option, on-chip space will be used as the program
memory. When boot from ROM is not selected by the strapping option, off-chip space will be used
as the program memory.
2. When updating firmware in the off-chip program memory, EP1/2 SRAM is used as the temporary
program memory storage. Under this mode, the lowest 4k address will be mapped to EP1/2 buffer.
6.2 Data Memory Space
The 256 bytes of internal registers and up to 64k bytes of external data memory can be accessed by the
8032 core. (The boundary of internal/external is the 8032 core.)
6.3 MCU Internal Registers
Please refer to the following Table 3 for the memory map of MCU Internal Registers.
