— 12 Bit AD Resolution
— Up to 10 bit accuracy at 400 ksample/s and 8 bit accuracy at 800 ksample/s
— Differential conversions
— Single-ended signal range from 0 to 5V
— Sample times of 2 (default), 8, 64 or 128 ADC clock cycles
— Provides time stamp information when requested
— Parallel interface to eQADC CFIFOs and RFIFOs
— Supports both right-justified unsigned and signed formats for conversion results
0 - 5V common mode conversion range
40 single ended inputs channels (40 in 416 BGA; 40 in 324 BGA; 34 in 208 BGA), with support
for up to 25 additional channels using external multiplexers (on all packages)
8 channels can be used as 4 pairs of differential analog input channels
10 bit accuracy at 400 ksample/s, 8 bit accuracy at 800 ksample/s
Supports six FIFO queues with fixed priority.
Queue modes with priority-based preemption, initiated by software command or internal (eTPU
and eMIOS) or external triggers
DMA and interrupt request support
Supports all functional modes from QADC (MPC5xx family)
4 pairs of differential analog input channels
Full duplex synchronous serial interface (SSI) to an external device
— Free-running clock for use by an external device
— Supports a 26-bit message length
Priority based CFIFOs
— Supports six CFIFOs with fixed priority. The lower the CFIFO number, the higher its priority.
— Supports software and hardware trigger modes to arm a particular CFIFO
— Generates interrupt when command coherency is not achieved
External hardware triggers
— Supports rising edge, falling edge, high level and low level triggers
— Supports configurable digital filter
Supports 4 external 8-to-1 muxes which can expand the input channels
3 DSPI modules
SPI
When commands of distinct CFIFOs are bound for the same CBuffer, the higher priority
CFIFO is always served first
