Datasheet NLM0011 / NLM0010 NFC-PWM Series (Infineon) - 5

NLM0011/ NLM0010 " NFC-PWM Series " NFC Wireless Configuration IC with PWM Output 2 Feature Overview
- if external supply voltage is present, NVM cannot accessed by external reader - the device is detecting switch off of external power supply by observing the external supply voltage level and detecting the resulting under voltage condition. The system has stored energy - internal and external capacitance - to save the current system status into the NVM before the power disappears. • in configuration mode the device is supplied from the harvested energy of the electromagnetic field of the NFC reader.
LED Current Setpoint Definition by PWM
• typical logical levels of PWM output are 0V (logic Low) and 2.8V (logic High) • period/ Frequency of PWM signal programmable between 1kHz and 30kHz • Duty cycle programmable between 0% and 100% • resolution/ granularity depends on PWM Frequency (~14.73 bit@ 1kHz; ~9.82bit@30kHz)
Operational Time Counting (OTC)
The Device is counting the operation hours and stores the value of overall operation time every 4 hours into the NVM. The device detects a power-off event and stores the current value of operation into the NVM before the chip is switched off.
On/ Off Counting
The device is counting the number of power on/ power off cycles and stores it in NVM.
Constant Lumen Output (CLO) (NLM0011 only)
The device is able to adjust the LED current setpoint value depending on an aging function over operating time. The aging function is end customer defined and stored in the NVM within device configuration. The aging function is defined between reference points. The setpoint value is interpolated between the setpoints, by taking the actual accumulated operating time into account. This feature is not available in NLM0010.
