OM5597/RD2612
POS Reference Design
7. Functional description
7.1 Content
The kit includes the following items:
OM5597/RD2612, Point of Sales board
1 USB cable
1 MIFARE DESFire
EV1 card
1 pre personalized JCOP Dual Interface card
The MIFARE SAM AV2 needs to be organized separately.
7.2 Hardware architecture
The POS reference board, see
Figure 1
, is composed out of the following NXP
components:
PN512/C2 contactless NFC reader IC supporting ISO/IEC 14443 type A and B, as
described in
Ref. 1
RF Amplifier for the PN512, as described in
Ref. 8
TDA8026 5-slot contact smart card IC, as described in
Ref. 2
Cortex M3 LPC1768, as described in
Ref. 3
a display for the user interface
a key pad for PIN entry within the closed loop payment showcase
The quick startup guide, see
Ref. 6
, gives directions how to start working with the POS
reference design. The board is structured of two main parts.
The main board provides the connections on the user interface (display and key pad), the
daughter board implements the main electronics such as the PN512, TDA8026 and
LPC1768. The antenna is part of the main board but is directly connected to the daughter
board. If one wants to remove the daughter board, the antenna needs to be unsoldered in
advance.
A serial interface (RS232) can be used to adapt or reprogram the software of the board
using FlashMagic.
7.2.1
Power supply
The board can be supplied using USB or over an external power supply connected to the
powerplug. To power the board with USB, the type-B USB connector must be connected
to a host computer through a USB cable. The jumper close to the USB type-B connector
must be set in order to connect VBUS to the 5 V input.
