Frequently Asked Questions
What makes the AT90PWM3B-16SU different from general-purpose AVR microcontrollers?
The AT90PWM3B-16SU features three dedicated Power Stage Controller (PSC) PWM channels with programmable dead-time insertion, unlike standard AVR MCUs. This hardware-level PWM control is specifically optimized for power electronics applications such as motor drives, inverters, and DC-DC converters operating at 16MHz.
What memory does the AT90PWM3B-16SU include?
The AT90PWM3B-16SU includes 8KB of in-system programmable Flash program memory, 512 bytes of SRAM for data storage, and 512 bytes of EEPROM for non-volatile parameter storage. This memory configuration supports real-time control firmware with persistent calibration and configuration data.
What communication interfaces are available on the AT90PWM3B-16SU?
The AT90PWM3B-16SU provides an SPI interface for high-speed peripheral communication, a USART for serial communication, and an I2C-compatible two-wire interface. These interfaces allow connection to external sensors, DACs, gate drivers, and host microcontrollers in multi-chip system designs.
What package does the AT90PWM3B-16SU come in?
The AT90PWM3B-16SU is packaged in a 32-pin SOIC (Small Outline Integrated Circuit) wide-body surface-mount package. The 'SU' suffix denotes this SOIC package, which offers good thermal performance and is compatible with standard SMT assembly processes used in industrial and automotive electronics manufacturing.
What supply voltage range does the AT90PWM3B-16SU operate at?
The AT90PWM3B-16SU operates from a supply voltage of 2.7V to 5.5V, making it compatible with both 3.3V and 5V system designs. At 16MHz maximum clock frequency, it delivers efficient real-time control performance suitable for embedded motor control and power management applications.
