Introduction

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.

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
