Peripherals maximise 8-bit motor-control credentials

The Z8FMC16100 MCU introduced by Zilog supports high-performance Brushless DC (BLDC) motor control at a competitive price by providing integrated peripherals such as an optimised PWM module, 2.5µs A/D converter with time-stamp capability, an integrated operational amplifier for current sampling, and multiple communication engines.

The 8-bit device is optimised for control of single- and multi-phase variable-speed motors. The PWM module can be configured as three complementary pairs or six independent PWM outputs supporting dead-band operation. There is also a trip input for fault protection. These features enable multi-phase control capability for a variety of motor types. Pulse-by-pulse control or latched fast-shutdown of the PWM pins during a fault condition ensures safe operation of the motor. There is also a fast A/D converter with an integrated sample-and-hold circuit, which provides up to eight single-ended channels of 10-bits resolution for voltage, current, and back-EMF sensing. The Z8FMC16100’s integrated current-sensing operational amplifier combines with an on-chip comparator to support over-current limiting or shutdown. A Hall-effect sensor interface can be implemented using the 16-bit timer also available on-chip. This timer also has capture/compare PWM capability. A full-duplex 9-bit UART supports asynchronous serial communications including the Local Interconnect Network (LIN) protocol for data rates up to 20kbit/s.
