– Dedicated interrupt for PWM duty cycles up-
– Programmable deadtime insertion unit.
– Programmable High frequency Chopper in-
– The output polarity is programmable channel
– A programmable bit (active low) forces the
– An “emergency stop” input pin (active low)
Two on-chip analog comparators, one for BEMF
zero-crossing detection, the other for current
regulation or limitation
Seven selectable reference voltages for the
hysteresis comparator (0.2 V, 0.6 V, 1 V, 1.5 V,
2 V, 2.5 V, 3.5 V) and the possibility to select an
external reference pin (MCVREF).
8-bit timer (MTIM) with three compare registers
and two capture features, which may be used as
the Delay manager of a speed measurement
unit
Measurement window generator for BEMF
zero-crossing detection
Filter option for the zero-crossing detection.
Auto-calibrated prescaler with 16 division steps
8x8-bit multiplier
Phase input multiplexer
Sophisticated output management:
groups (high & low)
low or both groups, alternatively or simultane-
ously, for six-step motor drives
pability (0 and 100% duty cycle), edge or cent-
er-aligned patterns
dating and associated PWM repetition coun-
ter.
sertion and high current PWM outputs for di-
rect optocoupler drives.

outputs in HiZ, Low or High state, depending
on option byte 1 (refer to “ST7FMC Device
Configuration And Ordering Information” sec-
tion).
asynchronously forces the outputs in HiZ, Low
or High state, depending on option byte 1 (re-
fer to “ST7FMC Device Configuration And Or-
dering Information” section).
