1 About This Document
1.1 Purpose and Audience
This document is intended for use by Cypress and customers’ test engineers.
1.2 Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due
to this conversion, there is no change in form, fit, or function as a result of offering the device with Cypress part
number marking. The table provides Cypress ordering part number that matches an existing IoT part number.

Note: For information regarding the measurement of current consumption of Bluetooth Low Energy devices, refer
to the document cited in Reference [1] on page 2.
3.2 Orientation
The following provides information that the user needs to know before starting to make current consumption mea-
surements:
■Cypress BlueTool™ is used to place the device under test (DUT) in each mode. To obtain the latest version,
contact your Cypress representative.
■The equipment needed for making power consumption measurements is described in System Requirements
on page 3.
■It is assumed that you are familiar with BlueTool and that you know how to set up and use the equipment
needed for measuring current consumption.
■The procedure for downloading the BlueTool configuration and minidriver files to the DUT and reference board
is also provided (see Downloading the Minidriver and Configuration File on page 4). You must download these
files to the devices before you begin setting the various modes.
■In this document, HCI control: com4 refers to the DUT, and HCI Control: com5 refers to the reference board.
The actual COM port number may be different for each test system.
■The number key shortcuts to switch to the various HCI command lists refer to the number keys above the letter
keys on the keyboard.
■WLAN core is in reset (WL_REG_ON = low) for all measurements.

Measuring Current Consumption in Different Power Modes
www.cypress.com Document No. 002-14914 Rev. *C 4
BlueTool is a proprietary Cypress software tool for exercising, testing, scripting, debugging, and programming
devices that use Cypress Bluetooth chips. BlueTool runs on a standard PC running Microsoft Windows (either
Windows XP or Windows 7). BlueTool interfaces with the Cypress Bluetooth chips at the HCI protocol layer.
Firmware/configuration files and minidriver files for the BCM4324/BCM4334 are available via Cypress’s Customer
Support Portal (see IoT Resources on page 2).
4.2 Test Equipment Setup
Connect the test equipment as shown in Figure .
■Use USB/RS-232 (straight-through) cables to connect the DUT to the PC.
■Use USB/RS-232 (straight-through) cables to connect the reference board to the PC.
■Using appropriate lead wires, connect the attenuator to the RF port of both the DUT and reference board.
■Using appropriate lead wires, connect the ammeter to VBAT on the DUT.

The range setting on the ammeter varies depending on the test mode. The ammeter range setting is specified in
the procedure for that test mode.
