3.2 Modules
3.2.1 Core
The core of the system shown above in figure 3.1, is the part of the modules’ hardware and firmware responsible for
managing tasks, prioritizing them and allocating resources to other components of the system. When the user sends
a command, the core is the part of the system which ensures that the command is executed properly, that the
outcome is saved and that a response is sent back to the user’s master controller.

3.2.2 RFID
The RFID component is the part of the hardware and module firmware responsible for the complete communication
interaction with the transponder via RF. In the RFID A1 module this part currently provides communication
capabilities with Mifare Classic, Ultralight and NTAG2 transponder types. The key features of this RFID section are
both fastest speed of transmission and system responsiveness, and optimal low power consumption.

3.2.3 Communication System
The Communication System component of the RFID A1 module is responsible for the entire communication with the
user master controller, together with parsing commands for subsequent execution by the module core. Two
communication interfaces are available: SPI and I2C. Both have equivalent access to the Communication System. It is
possible to communicate with the module using all two interfaces at the same time, but it is strongly recommended
to select and use only one at a time.

Communication peripherals are always active unless the nPWRDN signal is asserted. Doing so will put the module
into Deep Sleep Mode and turn off entire Communication System.

3.2.4 Power Manager
The Power Manager is the part of the firmware, together with hardware support, that manages the power states of
the system and tries to minimize power consumption as much as possible. The user has the option to put the module
into Power Down Mode by pulling low the nPWRDN pin.

into Power Down Mode by pulling low the nPWRDN pin.
When the system enters Power Down Mode, all clocks and submodules are disabled and no response to user
communication commands will occur until the system is re-enabled by the nPWDN being taken high by the user’s
system.
