Figure 3 Application Circuit
3.1 Power Supply
PRM90U10A should be supplied by 2 kinds of 3.6 volts DC power; VDD_36(Pin 1) and VDDPA_36(Pin 20,
21). VDD_36 is for operating of PR9000 RFID reader chipset which current consumption is about 150mA.
VDDPA_36 is for operating of power amp which current consumption is 350mA typically.
Additionally, decoupling capacitors should be placed as close as possible these pins. The decoupling
capacitors should be placed in the same layer as the module, to avoid any additional parasitic inductance
caused by vias.
3.2 Hardware Mode Control
PRM90U10A provides normal mode and shut down mode. The mode can control by SHDNb(Pin 24).
Normal mode should be controlled by SHDN pin to open which can activate the module. Otherwise, If SHDNb
pin contact to ground, supplied power of the module is shut down internally. In shut down mode, all GPIO
ports and UART ports should not input any signal and positive voltage.
3.3 UART
The serial interface assigned to two pins. RXD1(Pin 13) is for receiving command from host and TXD1(Pin 14)
is for transmitting response to host. Pin connection is shown as below figure.

For firmware downloading in PRM90U10A should be used GenICE3000 by CORERIVER(manufacturer),
which downloading speed is faster than UART. Code memory(62kB) and EEPROM(2kB) can be programmed
using EJTAG in target.
Following configuration is used for downloading to GenICE3000.

3.5 GPIO
PRM90U10A provides 16 bi-directional I/O ports. All ports can be configured in two different modes: open-
drain (by default) and push-pull which has 3.3V input and 3.3V output.
3.6 RF In/Out
RF I/O(Pin 20) is optimized at 50 ohms impedance.
3.7 Using GUI
The GUI is for the user to be able to quickly get started working with PRM90U10A RFID reader. To run the
GUI, click the Windows start button, Program menu, Phychips, PR9000 SDK. After start-up, a window will be
opened as shown below.
