AT89LP51RD2/ED2/ID2 Summary - Preliminary
2.3.9
Security
The AT89LP51RD2/ED2/ID2 does not support the external access pin (EA). Therefore it is not
possible to execute from external program memory in address range 0000H–1FFFH. When the
third Lockbit is enabled (Lock Mode 4) external program execution is disabled for all addresses
above 1FFFH. This differs from AT89C51RD2/ED2/ID2 where Lock Mode 4 prevents EA from
being sampled low, but may still allow external execution at addresses outside the 8K internal
space.
2.3.10
Programming
The AT89LP51RD2/ED2/ID2 supports a richer command set for In-System Programming (ISP).

AT89LP51RD2/ED2/ID2 in byte mode. In page mode the AT89LP51RD2/ED2/ID2 only supports
programming of a half-page of 64 bytes and therefore requires an extra address byte as com-
pared to AT89C51RD2/ED2. Furthermore the device signature is located at addresses 0000H,
0001H and 0003H instead of 0000H, 0100H and 0200H.
