This board can be plugged as in Fig 1, using the TWR-ELEV boards (side connector
boards).
When plugging this board, the Primary and Secondary connection sides have to be
respected. PCI secondary and primary connector are identified on TWR-POS-CLRC663,
and on TWR-ELEV card, see below figure.

1.2 Architecture
The TWR-POS-CLRC663 peripheral board embeds ICs to provide Contact and
Contactless payment functionalities.
The board uses the following ICs:
- CLRC663: NXP Contactless Front-end reader
- TDA8035: NXP Contact Front-end reader device.
Both devices are compliant with latest payment specifications (EMVCo)
The reader ICs are controlled by an MCU or processor module, through the side
connectors, plugged on Tower system.
In order to interface with smart cards, the TWR-POS-CLRC663 board is autonomous as
it embeds an antenna connected to CLRC663 to interact with Contactless cards, and a
contact smart card connector, connecting the smart card to the TDA8035.

1.3 Configuration
The TWR-POS-CLRC663 peripheral board embeds several configuration jumpers. They
are used to enable several Tower MCU or processor modules to be used as the
controller.
Below table shows the default configuration when the TWR-K80F150M is used as the
MCU module. Other configurations can be set depending on the MCU or processor
module board that is used.
