AVR for Lighting
AT90PWM devices have been specially developed to handle ballasts for High Intensity Discharge
(HID) and dimmable fluorescent lamps.
They feature enhanced 12-bit PWM to realize the Power Factor Correction and control the ballast.
With an embedded EEPROM allowing to save configuration parameters and necessary analog
functions, the microcontrollers help to reduce ballast component count and system cost.
The Digital Addressable Lighting Interface (DALI) protocol is also supported, allowing highly
flexible user control.
a) Pb-free packaging complies to the European Directive for Restriction of Hazardous Substances (RoHS directive). Also Halide free and fully Green.
b) F: Future product , I: Device under Introduction, P: Product in Full Production.
