The MCS@51 controllers are optimized for control applications. Byte-processing and numerical operations on
small data structures are facilitated by a variety of fast addressing modes for accessing the internal RAM. The
instruction set provides a convenient menu of 8-bit arithmetic instructions, including multiply and divide instruc-
tions. Extensive on-chip support is provided for one-bit variables as a separate data type, allowing direct bit
manipulation and testing in control and logic systems that require Boolean processing.
The 8751H is an EPROM version of the 8051AH. It has 4 Kbytes of electrically programmable ROM which can
be erased with ultraviolet light. His fully compatible with the 8051AH but incorporates one additional feature: a
Program Memory Security bit that can be used to protect the EPROM against unauthorized readout. The
8751 H-8 is identical to the 8751 H but only operates up to 8 MHz.
The 8051AHP is identical to the 8051AH with the exception of the Protection Feature. To incorporate this
Protection Feature, program verification has been disabled and external memory accesses have been limited
to 4K.
The 8052AH is an enhanced version of the 8051AH. It is backwards compatible with the 8051AH and is
fabricated with HMOS II technology. The 8052AH enhancements are listed in the table below. Also refer to this
table for the ROM, ROMless and-EPROM versions of each product.

DESIGN CONSIDERATIONS
If an 8751 BH or 8752BH is replacing an 8751 H in
a future design, the user should carefully com-
pare both data sheets for DC or AC Characteris-
tic differences. Note that the VIH and IIH specifi-
cations for the ~ pin differ significantly between
the devices.
Exposure to light when the EPROM device is in
operation may cause logic errors. For this reason,
it is suggested that an opaque label be placed
over the window when the die is exposed to am-
bient light.
q The 8051AHP cannot access external Program
or Data memory above 4K. This means that the
following instructions that use the Data Pointer
only read/write data at address locations below
OFFFH:
MOVX A,@DPTR
MOVX (6JDPTRA,
When the Data Pointer contains an address
above the 4K limit, those locations will not be ac-
cessed.
To access Data Memory above 4K, the
MOVX @Ri,A or MOVX A,@Ri instructions must
be used.
