1.5.32

Sine Wave Generator (SWG)

A digital-to-analog converter is available to generate a sine wave based on 32 stored values for external devices (ex: resolver).

•

Frequency range from 1 kHz to 50 kHz

•

Sine wave amplitude from 0.47 V to 2.26 V

1.5.33

Analog-to-Digital Converter Module (ADC)

The ADC module features include:

Analog part:

•

2 on-chip ADCs

— 12-bit resolution SAR architecture

— A/D Channels: 9 external, 3 internal and 4 shared with other A/D (total 16 channels)

— One channel dedicated to each T-sensor to enable temperature reading during application

— Separated reference for each ADC

— Shared analog supply voltage for both ADCs

— One sample and hold unit per ADC

— Adjustable sampling and conversion time

Digital part:

•

4 analog watchdogs comparing ADC results against predefined levels (low, high, range) before results are stored in

the appropriate ADC result location

•

2 modes of operation: Motor Control Mode or Regular Mode

•

Regular mode features

— Register based interface with the CPU: one result register per channel

— ADC state machine managing three request flows: regular command, hardware injected command, software

injected command

— Selectable priority between software and hardware injected commands

— 4 analog watchdogs comparing ADC results against predefined levels (low, high, range)

— DMA compatible interface

•

Motor control mode features

— Triggered mode only

— 4 independent result queues (1

 16 entries, 2  8 entries, 1  4 entries)

— Result alignment circuitry (left justified; right justified)

— 32-bit read mode allows to have channel ID on one of the 16-bit parts

— DMA compatible interfaces

•

Built-in self-test features triggered by software
