The S08MP16 is a cost-effective 8-bit MCU that delivers safe, accurate and inexpensive motor control for a wide range of industrial and automotive applications. An ideal entry-level solution for brushless DC (BLDC) motor applications, it features an 8-channel pulse width modulator (PWM)/flextimer module providing hardware dead-time insertion, analog comparators, programmable gain amplifier and a 12-bit analog-to-digital converter (ADC) with PWM hardware triggering. Also offered is an independently clocked COP and cyclic redundancy check (CRC) engine providing clock failure protection and memory content validation for safety-critical applications implementing IEC60730.
