1.1 LP3500 Description
The LP3500 is a low-power single-board computer that incorporates the powerful and
low-EMI Rabbit 3000 microprocessor, flash memory, static RAM, digital I/O ports, A/D
converter inputs, PWM outputs, RS-232/RS-485 serial ports, and both parallel and serial
interfaces that allow other devices to be connected to the LP3500.
All aspects of the LP3500 are designed for low power consumption and operates at a vari-
ety of power levels, including a power-save mode, to fit customer-specified conditions at
any given time. The CPU runs at a nominal speed of 7.4 MHz, and operates at 2.8 V to
conserve power. The LP3500 consumes less than 20 mA when fully operational, and less
than 100 µA when in the power-save mode. A replaceable coin-type battery will allow the
LP3500 to operate in sleep mode for over 3 years. The LP3500 is normally powered from
an external battery or power supply. When the unit is in the power-save mode, it can be
awakened by an internal timer, an RS-232 signal, or via polling of an external input. The
LP3500 can be switched from the power-save mode to full operation and back under pro-
gram control. In addition, various sections of circuitry (such as the RS-232 ports) can be
switched off under program control to further conserve power when not in use.
User’s Manual
The LP3500 is a low-power single-board computer with built-in
analog and digital I/O. Although the LP3500 was designed spe-
cifically for low-power applications and data logging, it has a
host of features that make it attractive for other applications as
well. Low power is often required in portable equipment operat-
ing from batteries or from solar power. The LP3500 is ideal for
monitoring equipment or processes that are far-removed from a
power supply, remote telemetry (RTUs), pipeline control and
monitoring, well-head monitoring; and use on mobile equipment
such as refrigeration trucks. An optional plastic enclosure and an
LCD/keypad module are available.
The Tool Kit has the essentials that you need to design your own
low-power microprocessor-based system, and includes a com-
plete Dynamic C software development system.
