NLM0011/ NLM0010 " NFC-PWM Series " NFC Wireless Configuration IC with PWM Output 5 Functional Description
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 either be supplied by energy harvested from the NFC field or by an external VCC source. In case an external VCCsource is present the NLM0011 chip enters the lighting operational mode and no NFC operation incl. energy 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.
