5 AFE44x0SPO2EVM Hardware

CAUTION

Many of the components on the AFE44x0SPO2EVM are susceptible to damage

by electrostatic discharge (ESD). Customers are advised to observe proper

ESD handling precautions when unpacking and handling the EVM, including

the use of a grounded wrist strap, bootstraps, or mats at an approved ESD

workstation. Safety glasses should also be worn.

The key features of the AFE44x0 Analog Front End demonstration board are:

• Based on MSP430F5529

• DB9 pulse oximeter sensor cable support

• Two modes of operation: Evaluation and Live SPO2 / Heart rate

• Acquire data at up to 1300 Hz in evaluation mode

• SPI Data interface

The AFE44x0SPO2EVM board can be used as a demo board for pulse oximeter and heart rate

applications. The BOM is provided in Section 10. The printed circuit board (PCB) and schematic are

shown in Section 11.1 and Section 11.2, respectively.

MSP430F5529 (U2 – see Section 11.2) is the microcontroller used on the board. For more details of the

MSP430F5529 please visit http://focus.ti.com/docs/prod/folders/print/msp430f5529.html

The following sections explain the main hardware components available on the EVM. Figure 29 shows the

functional block diagram for the EVM.
