WT58F032
【 General Description 】
The WT58F032 is a high-performance 32-Bit Microcontroller. It incorporates the 32-bit RISC CPU operating up to50 MHz, Flash memory up to 32K bytes and SRAM up to 4K bytes, and rich peripherals/interfaces such as high-speed ADC, high-speed PWM, current limit comparator, Quadrature Encoder Interface (QEI), I2C, SPI, UART and LIN bus.
The WT58F032 is suitable for a wide range of applications, such as Brush-less DC motor (BLDC) control, AC induction motor control, switched reluctance (SR) motor control, digital power control, DC/DC, AC/DC, Inverters, PFC, washing machine, air conditioner, refrigerator, LED lighting control and applications where high computing power and high-speed communication are required.

● Comparators
  - A comparator is equipped with two channels (CMP0, CMP1)
  - Negative-side input pins (CMP0M, CMP1M) and a positive-side input pin (CMP0P, CMP1P) can be connected
  - CMP0M and CMP1M pin inputs and the internal generation reference voltage (6 combinations for each comparator) can be selected as the reference voltage
  - The elimination width of the noise elimination digital filter can be selected
  - An interrupt request is generated when an overvoltage is detected (INTCMP0 and INTCMP1) Interrupt on position counter rollover/underflow
  - The output signal of comparator is connected to the PWM array unit and sets the PWM output pin to a non-active state
