8XC51FX
ONCE MODE
The ONCE (``On-CircuitEmulation'') Mode facilitates
testing and debugging of systems using the
8XC51FX without the 8XC51FX having to be re-
moved from the circuit. The ONCE Mode is invoked
by:
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 8XC51FX is in this mode, an emulator
or test CPU can be used to drive the circuit. Normal
operation is restored when a normal reset is applied.
8XC51FX 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
standards.
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 b 40°C to
a 85
°C.
The optional burn-in is dynamic for a minimum time
of 168 hours at 125
°C with VCC =6.9V g 0.25V,
following guidelines in MlL-STD-883, Method 1015.
For the extended temperature range option, this
data sheet specifies the parameters which deviate
from their commercial temperature range limits.
NOTE
:
Intel offers Express Temperature specifica-
tions for all 8XC51FX speed options except
for 33 MHz.
