Preliminary specification
P87C51MB2/P87C51MC2
80C51 8-bit microcontroller family with extended memory
64KB/96KB OTP with 2KB/3KB RAM
SECURITY BITS
The P87C51Mx2 has security bits to protect users’ firmware codes. With none of the security bits programmed, the code in the
program memory can be verified. With only security bit 1 (see Table 6) is programmed, MOVC instructions executed from
external program memory are disabled from fetching code bytes from the internal memory. EA is latched on Reset and all further
programming of EPROM is disabled. When security bits 1 and 2 are programmed, in addition to the above, verify mode is
disabled. When all three security bits are programmed, all of the conditions above apply and all external program memory
execution is disabled.

Protection Description
No program security features enabled. EEPROM is programmable and verifiable.
MOVC instructions executed from external program memory are disabled from fetching
code bytes from internal memory, EA is sampled and latched on Reset, and further
programming of the EPROM is disabled.
Same as 2, also verification is disabled.
Same as 3, external execution is disabled.
