Introduction

2.1

Intended Functionality

The blood pressure monitor (BPM) reference design shows how to implement a system that can measure

arterial blood pressure values. The system demonstrates control, data retention, analog acquisition, and

connectivity functions, as well as the ability to interface with a user. These are achieved by using several

Freescale devices.

This reference design serves only as a proof of concept for this application and is not authorized for use in

safety-critical applications such as a U.S. Food and Drug Administration (FDA) class 3 application.

Manufacturers and designers who incorporate Freescale (FSL) technology must have all necessary

expertise in the safety and regulatory ramifications involved in the application of this design, and they are

solely responsible for all legal, regulatory, and safety-related requirements concerning their products and

the use of Freescale devices in safety-critical applications.

2.2

Solution Benefits

The BPM reference design elements can be referenced for later development as:

•

USB communication using the MC9S08JM60 as a bridge

•

2.4 GHz communication using the MC13202 ZigBee transceiver

•

MRAM communications

•

Use of MRAM to store user data

•

MRAM driver to access MRAM memory

•

User display using an OLED display

•

User interface using the MPR083 proximity sensor

•

Audio feedback using two timer pulse-width modulator (TPM) modules

The main benefit from this solution is that developers are able to take any piece of hardware and/or

software and reuse it for their own applications, thus enhancing the design cycle and providing faster

development time.
