P89LPC9102/9103/9107
8-bit microcontrollers with two-clock accelerated 80C51 core
After power-up all I/O pins, except P1.5, may be configured by software.
Pin P1.5 is input-only.
Every output on the P89LPC9102/9103/9107 has been designed to sink typical LED drive
current. However, there is a maximum total output current for all ports which must not be
exceeded. Please refer to
Table 12 “Static characteristics”
for detailed specifications.
All ports pins that can function as an output have slew rate controlled outputs to limit noise
generated by quickly switching output signals. The slew rate is factory-set to
approximately 10 ns rise and fall times.
8.13 Power monitoring functions
The P89LPC9102/9103/9107 incorporates power monitoring functions designed to
prevent incorrect operation during initial power-up and power loss or reduction during
operation. This is accomplished with two hardware functions: Power-on Detect and
Brownout detect.
8.13.1
Brownout detection
The Brownout detect function determines if the power supply voltage drops below a
certain level. The default operation is for a Brownout detection to cause a processor reset,
however, it may alternatively be configured to generate an interrupt.
Brownout detection may be enabled or disabled in software.
If Brownout detection is enabled, the brownout condition occurs when V
DD
falls below the
brownout trip voltage, V
BO
(see
Table 12 “Static characteristics”
), and is negated when
V
DD
rises above V
BO
. If the P89LPC9102/9103/9107 device is to operate with a power
supply that can be below 2.7 V, Brownout detect Enable (BOE) should be left in the
unprogrammed state so that the device can operate at 2.4 V, otherwise continuous
brownout reset may prevent the device from operating.
For correct activation of Brownout detect, the V
DD
rise and fall times must be observed.
Please see
Table 12 “Static characteristics”
for specifications.
8.13.2
Power-on detection
The Power-on Detect has a function similar to the Brownout detect, but is designed to
work as power comes up initially, before the power supply voltage reaches a level where
Brownout detect can work. The Power-on detect flag (POF) in the RSTSRC register is set
to indicate an initial power-up condition. The POF flag will remain set until cleared by
software.
8.14 Power reduction modes
The P89LPC9102/9103/9107 supports three different power reduction modes. These
modes are Idle mode, Power-down mode, and Total Power-down mode.
8.14.1
Idle mode
Idle mode leaves peripherals running in order to allow them to activate the processor
when an interrupt is generated. Any enabled interrupt source or reset may terminate Idle
mode.
