1 Introduction

This user manual describes how to use NXP's PCAL6416AEV test board. This board is designed for testing functional characteristics of the PCAL6416AEV part, saving time for NXP customer qualification of the 16-bit Agile GPIO expander. This board works with NXP's Fm+ demo board (OM13260) or any customer I2C-bus controller. It has a socket for VFPGA24 3x3 mm, a 14-pin connector for FM+ demo board using 3.3V, and two external power supply TPs for VDDI and VDDP of the PCAL6416AEV, as well as an I2Cbus header for customer I2C controller.

2 Features and benefits

• Direct connection to OM13320 Fm+ Development kit

• External I2C-bus connection

• Isolated power rail for power measurement

• Socket of VFPGA24 3x3 mm with 0.30 mm ball size

• Flexible power supply configuration: 3.3V or external supply

• Direct connection to OM13303 GPIO Target board for I/O visualization

• Jumper configuration of device I2C address

• LED indicators for power and INT

9. External I2C SCL signal input from CN2 (SCL: Beagle master)

10.CN3 and CN4 are 2x5 female headers connected to OM13303 GPIO Target board for I/O visualization

11.LED power for INT(D1) signal and VPP(D2) power indicator

12.J2 is Reset jumper for PCAL6416AEV

4 Using NXP PCAL6416AEV with Fm+ demo board

1. Get I2C Fm+ Development Board Kit package at: http://www.nxp.com/demoboard/

OM13320.html

2. Connect CN2 of NXP PCAL6416AEV to any port A, B, C or D on Fm+ demo board

3. Set jumpers:

• J1 = 2-3 for +3V3 for VDDP_IN

• J3 = enabling power for VDDP

• J4 = 1-2 for +3V3 for VDDI_IN

• J5 = enabling power for VDDI

• J6 = 3-4 for PCAL6416AEV slave address = 0x010-0000 (40h)

4. Set jumpers:

• Use multi-meter at J3 for VDDP and J5 for VDDI

5. Test GPIO outputs and Interrupt a. Put jumper on J4:1-2 & J5 to enable power of D1 LED indicators for INT and PWR b. Connect OM13303GPIO Target Boards (Fm+ demo board kit) to CN3 and CN4 c. Connect USB from Fm+ demo board to the PC with NXP Fm+ software
