ONCE MODE
The ONCE (‘‘On-Circuit Emulation’’) mode facilitates
testing
and
debugging
87C51/BH without the 87C51/BH having to be re-
moved from the circuit. The ONCE mode is invoked
by:
of
systems
using
the
1. Pull ALE low while the device is in reset and
PSEN is high;
2. Hold ALE low as RST is deactivated.
While the device is in ONCE mode, the Port 0 pins
float, and the other port pins and ALE and PSEN are
weakly pulled high. The oscillator circuit remains ac-
tive. While the 87C51/BH is in this mode, an emula-
tor or test CPU can be used to drive the circuit. Nor-
mal operation is restored when a normal reset is ap-
plied.
87C51/BH EXPRESS
The Intel EXPRESS system offers enhancements to
the operational specifications of the MCS-51 family
of microcontrollers. These EXPRESS products are
designed to meet the needs of those applications
whose operating requirements exceed commercial
temperature.
The EXPRESS program includes the commercial
standard temperature range with burn-in and an ex-
tended temperature range with or without burn-in.
With the commercial standard temperature range,
operational characteristics are guaranteed over the
temperature range of 0

C to 70

C. With the extend-
ed temperature range option, operational character-
istics are guaranteed over the range of

The optional burn-in is dynamic for a minimum time
of 160 hours at 125

following guidelines in MIL-STD-883, Method 1015.
Package types and EXPRESS versions are identified
by a one- or two-letter prefix to the part number. The
prefixes are listed in Table 3.
For the extended temperature range option, this
data sheet specifies the parameters which deviate
from their commercial temperature range limits.

Examples:
P87C51 indicates 87C51 in a plastic package and
specified for commercial temperature range, without
burn-in.
LD87C51 indicates 87C51 in a cerdip package and
specified for extended temperature range with burn-
in.
