9.6.2 Main Features

s Two on-chip analog comparators, one for BEMF

zero-crossing detection, the other for current

regulation or limitation

s 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).

s 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

s Measurement window generator for BEMF

zero-crossing detection

s Filter option for the zero-crossing detection.

s Auto-calibrated prescaler with 16 division steps

s 8x8-bit multiplier

s Phase input multiplexer

s Sophisticated output management:

– The six output channels can be split into two

groups (high & low)

– The PWM signal can be multiplexed on high,

low or both groups, alternatively or simultane-

ously, for six-step motor drives

– 12-bit PWM generator with full modulation ca-

pability (0 and 100% duty cycle), edge or cent-

er-aligned patterns

– Dedicated interrupt for PWM duty cycles up-

dating and associated PWM repetition coun-

ter.

– Programmable deadtime insertion unit.

– Programmable High frequency Chopper in-

sertion and high current PWM outputs for di-

rect optocoupler drives.

– The output polarity is programmable channel

by channel.

– A programmable bit (active low) forces the

outputs in HiZ, Low or High state, depending

on option byte 1 (refer to “ST7FMC Device

Configuration And Ordering Information” sec-

tion).

– An “emergency stop” input pin (active low)

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).
