AT90PWMx

AT90PWMx AVR© by Atmel has been designed for lamp ballast and motor control applications. Both the 8-Kbyte Flash AT90PWM3 and AT90PWM2  allow high flexibility in controlling light levels, energy savings and easy to maintain. The 4-Kbyte Flash AT90PWM1 is cost effective.

The AT83EB5114 is available in a low-pin-count SO20 package and supports a 4-Kbyte ROM and a 256-byte EEPROM.

To reduce EMI by generating current in phase with the supplied voltage, the device requires a Power Factor Correction (PFC). In order to  manage the PFC functionality and control the lamp power, the microcontrollers have dedicated peripherals.

The AT90PWM2 is available in SO24; the AT90PWM3 is available in SO32 or MLF/QFN32.
