Abstract
Installation guide and User Manual for the OM13541 34-bit GPIO Daughter
Card that connects to OM13260 Fm+ I2C bus development board. This
daughter board makes it easy to test and design with the PCAL6534, an ultra-
low voltage translating 34-bit general purpose I/O expander that provides
remote I/O expansion for most microcontroller families via the Fast-mode
Plus (Fm+) I2C-bus interface. This daughter board, along with the Fm+
Development board, provides an easy to use evaluation platform.

  • Page 5: Hardware Description

    Hardware description 3.1 Power supply jumpers The power supply selection for the OM13541 is very flexible and allows for detailed analysis and evaluation of 34-bit GPIO device. J13 selects +5V_PWR supply from either the tester connector J1 (pins 4 and 6, +5V_TSTR) or the Fm+ board connector J11 (pins 7 and 12, +5V).

    UM11099 NXP Semiconductors PCAL6534 demonstration board OM13541 3.5 Connector pinouts • J1 (10-pin male tester connector) is connected to master which is driving either I bus for PCAL6534. This is easily achieved with third party development tools from Total Phase (http://www.totalphase.com). There are two tools called Aardvark and Beagle that direct connect to this board through J1.
