The MCS 51 CHMOS microcontroller products are fabricated on Intel’s reliable CHMOS process and are
functionally compatible with the standard MCS 51 HMOS microcontroller products This technology combines
the high speed and density characteristics of HMOS with the low power attributes of CHMOS This combina-
tion expands the effectiveness of the powerful MCS 51 microcontroller architecture and instruction set
Like the MCS 51 HMOS microcontroller versions the MCS 51 CHMOS microcontroller products have the
following features 4 Kbytes of EPROM ROM (87C51 80C51BH respectively) 128 bytes of RAM 32 I O lines
two 16-bit timer counters a five-source two-level interrupt structure a full duplex serial port and on-chip
oscillator and clock circuitry In addition the MCS 51 CHMOS microcontroller products exhibit low operating
power along with two software selectable modes of reduced activity for further power reduction Idle and
Power Down
The Idle mode freezes the CPU while allowing the RAM timer counters serial port and interrupt system to
continue functioning The Power Down mode saves the RAM contents but freezes the oscillator causing all
other chip functions to be inoperative
The 87C51 is the EPROM version of the 80C51BH It contains 4 Kbytes of on-chip program memory that can
be electrically programmed and can be erased by exposure to ultraviolet light The 87C51 EPROM array uses
a modified Quick-Pulse Programming algorithm by which the entire 4 Kbyte array can be programmed in about
12 seconds

PRODUCT OPTIONS
Intel’s extended and automotive temperature range
products are designed to meet the needs of those
applications whose operating requirements exceed
commercial standards
With the extended temperature range option opera-
tional characteristics are guaranteed over the tem-
perature range of b40 C to a85 C ambient For the
automotive temperature range option operational
characteristics are guaranteed over the temperature
range of b40 C to a125 C ambient
The automotive and extended temperature versions
of the MCS 51 microcontroller product families are
available with or without burn-in options as listed in
Table 1
As shown in Figure 2 temperature burn-in and
package options are identified by a one- or two-letter
prefix to the part number
270419 – 2
