PN544
Near field communication (NFC) controller
3. Features
Low power HT80C51 MX CPU core with 72 KBytes ROM, 44 KBytes non-volatile
memory for code, 8 KBytes non-volatile memory for data and 4 KBytes RAM
Buffered output drivers to connect an NFC antenna with minimum number of external
components
Integrated configurable Polling Loop for automatic device discovery
Integrated data mode detector for automatic anticollision
Integrated non-volatile memory to store data and executable code for customization
Flexible clock supply concept to facilitate PN544 integration
Integrated FracNPLL to make use of cellular reference clock
27.12 MHz direct clock input to minimize current consumption (integrated
FracNPLL disabled)
Internal oscillator to connect an 27.12 MHz crystal (in case of absent reference
clock, then FracNPLL is disabled to minimize current consumption)
Flexible power supply concept to facilitate PN544 integration
Integrated power management unit to be directly connected to a mobile battery
