hours. It updates the NVM by operational hours periodically or if the chip underruns a undervoltage emergency

threshold limit. It interpolates the CLO setting as well, according to the configured aged function . The

interpolation result changes the PWM frequency and duty cycle parameter dynamically, which are delivered to

the PWM generator. In configuration mode it provides NFC reader access to the NVM and responds to NFC

reader commands. It is implemented as a hard coded finite state machine.

PWM Generator and CLO Interpolator:

That functional block is configured by the start up and mode control with the PWM period and duty cycle

setting. It is only active in lighting operational mode and generates the PWM output according to configuration

and CLO until the chip is switched off (CLO function is only available in NLM0011).

Power Management and Distribution:

This unit includes the voltage regulators and under voltage lockout detection and control function. The chip can

harvesting is possible anymore.

Clock and Reset Generation/ Oscillator:

Internal clocks and resets are generated here. Architectural clock gating control is done as well. In configuration

mode the clock of 13,56 MHz is derived from the external NFC carrier by a clock recovery unit within the NFC

Transceiver. In lighting operational mode the clock is provided by internal oscillator running at 27,12MHz.
