Introduction

The function of the BS1 PDA module in RAE–2 Communicator device is to run all applications that utilize the PDA LCD display of the device. The GEOS operating system is applied on a 486 based PDA module platform. This processing platform utilizes the communicator–type user interface which is accessible when the RAE–2 is opened.

Technical Summary

The BS1 PDA module consists of a printed circuit board with a CPU, two kinds of memories, a Power unit, HF amplifier circuitry, and an IR–transceiver.

The PDA module is assembled on a single 8–layer printed circuit board. All components are assembled on one single side. The other side is reserved for keyboard keypads.

Technical Documentation

Serial ports, DMA– and LCD controller for timers are integrated in the CPU. The operating system is GEOS supplied by Geoworks.

The BS1 module includes three non–volatile Flash memories which are used for two kind of purposes. XIP (executed in place) memory is used for program file storage and RFD (resident flash disk) memory is writeable for user data.

One DRAM Memory is used for the code execution and for the volatile storage of the internal run–time system data.

Both memory types (DRAM and Flash) have their own address– and data bus, routed directly from the CPU.

The BS1 PWRU block regulates the PDA module power and controls the power-up and -down. After a battery has been connected, the PWRU gives the CPU system voltage and releases the reset as fast as possible after which the CPU SW has full power management control. The PWRU also generates and controls the voltages that the PDA LCD uses. The PDA has a rechargeable back–up battery which the PWRU block charges when the main battery is connected. The VBACK voltage is normally always available for real time clock. Power is fed from the battery through the CMT module to the PDA PWRU. The PWRU has a filter in battery line to reduce interference from the CMT module. The PWRU provides

Technical Documentation

A/D converter readings of the battery voltage and temperature via a parallel interface to the CPU. Many PWRU items can be controlled by register writing or directly via pin. The system voltage is always present until battery voltage drops below 3.0V.
