NFC-PWM configuration ICs

概要

Dual-mode NFC wireless configuration ICs with pulse width modulation (PWM) output for lighting applications

Infineon's NLM0011 is a dual-mode NFC wireless configuration IC with pulse width modulation (PWM) output, primarily designed for LED applications to enable NFC programming. In addition, advanced features such as the constant lumen output (CLO) as well as the on/off counting are integrated, with no need for an additional microcontroller. Since the NLM0011 is designed to work together with mainstream analog driver ICs, there are no firmware development efforts needed. It can be easily adapted into existing designs to replace the plug-in-resistor current configuration concept. The NLM0010 is a light version of the NLM0011 without CLO function.

NLM0011 and NLM0010 NFC-PWM configuration ICs are compatible with existing analog LED driver designs and with the NFC-programming specification from the Module-Driver Interface Special Interest Group (MD-SIG).

Key features of NLM0011 and NLM0010

Key features

  • Configurable pulse width modulation (PWM) output
  • NFC contactless interface compliant to ISO/IEC 18000-3 mode 1 (ISO/IEC 15963)
  • Constant light output (CLO) with 8 configurable points
  • Integrated operation-time counter (OTC) and on/off counter
  • Non-volatile memory (NVM) including UID and 20 bytes free memory for user data

Key benefits

  • Fast and cost effective implementation of NFC programming and CLO without the need of an additional microcontroller
  • Compatible with most analog LED driver designs using “plug-in resistor” method
  • Stable PWM output with fixed 2.8 V amplitude and +/-0.1% duty cycle accuracy
  • Internal voltage regulator (LDO) to avoid influence of instable external supply voltage
  • Compatible with the MD-SIG “NFC Programming Specification” 1
