Preliminary specification
P87C51MB2/P87C51MC2
80C51 8-bit microcontroller family with extended memory
64KB/96KB OTP with 2KB/3KB RAM
Notes:
*
SFRs are bit addressable.
# SFRs are modified from or added to the 80C51 SFRs.
Extended SFRs accessed by preceeding the instruction with 51MX escape (opcode A5h).
-
Reserved bits, must be written with 0’s.
& Power on reset is 10H. Other reset is 00H.
§ BRGR1 and BRGR0 must only be written if BRGEN in BRGCON SFR is ’0’. If any of them is written if BRGEN = 1, result is
unpredictable.
% The unimplemented bits (labeled ’-’) in the SFRs are ’X’s (unknown) at all times. ’1’s should NOT be written to these bits, as
they may be used for other purposes in future derivatives. The reset values shown for these bits are ’0’s although they are
unknown when read.
