EU6522T
- Description
- The high-performance motor drive chip incorporates ME core and 8051 core. ME core integrates FOC, MDU,
LPF, PID and SVPWM modules that allow for automatic calculation of FOC or square-wave control by the
hardware for sensored/sensorless BLDC/PMSM motors. 8051 core is used for parameter configuration and routine
processing. Most of 8051 core instruction cycle takes 1T or 2T clock cycle(s). The dual cores work in parallel to
achieve high-performance motor control. The chip integrates high-speed operational amplifiers, comparators,
high-speed ADC, CRC, SPI, I2C, UART, Timers and built-in LDO, which are suitable for FOC or square-wave
based BLDC/PMSM motors.
The above are the general descriptions on the product family. The features vary by models. See section 2 Pin
Definitions and 4 Ordering Information for details.
For concise description and easy differentiation, if it is specified that a feature is applied to a specific model,
the feature is exclusive to this model. For example, EU6572 refers to all models of EU6572, EU6522 refers all
models of EU6522, and so on. Otherwise, the feature is a common feature of the product family.
