Hardware Security System

User Space
Boot Space
Hardware Security Space
Extra Row Space
This space is composed of a 64K Bytes Flash memory organized in 512 pages of 128 Bytes. It
contains the user’s application code. This space can be read or written by both software and
hardware modes.
This space is composed of a 4K Bytes Flash memory. It contains the bootloader for In-System
Programming and the routines for In-System Application Programming.
This space can only be read or written by hardware mode using a parallel programming tool.
This space is composed of one byte: the Hardware Security Byte (HSB see Table 7) divided in
two separate nibbles see
Loader Jump Bit as detailed in section “Boot Memory Execution” and can be written by software
while the LSN contains the lock system level to protect the memory content against piracy as
detailed in section “Hardware Security System” and can only be written by hardware.
This space is composed of two Bytes:
•
•
The AT89C5132 implements three lock Bits LB2:0 in the LSN of HSB (see Table 7) providing
three levels of security for user’s program as described in Table 7 while the AT83C51SND1C is
always set in read disabled mode.

This byte is used by the software bootloader to build the boot address.
The Software Security Byte (SSB see
This byte is used to lock the execution of some bootloader commands.
Level 0 is the level of an erased part and does not enable any security feature.
Level 1 locks the hardware programming of both user and boot memories.
Level 2 locks hardware verifying of both user and boot memories.
Level 3 locks the external execution.
